Playlist: 1. Patch of The Week: The Sonic XV's Wave Folder - So many tones from just 1 VCO's Triangle wave

'Sonic Arps': The Sonic XV Transistor Diode Ladder Filter has a built-in Wave Folder, and in this video I'm using an arpeggiator in random mode to show the many subtle flavours of sound it can achieve from just a simple triangle wave from a single VCO. I will also pull a huge variety of timbres from a sine wave in a similar fashion.
The filter is a re-creation and expansion of the VCF from the Musonics Sonic V (5) synth of the 1970's (predecessor of the Moog Sonic Six), and shares a similar character to that of the EMS Synthi and VCS3, also being early diode filters. Bearing that in mind you might expect it to produce aggressive tones and chaotic feedback, which it can do well enough, but you might not have expected that it can also be very subtle, organic and warm in character, particularly well-suited to melodic arps/patterns and percussive sounds. With the added wave shaping functionality that wasn't present on the original, along with 24dB and 6dB low pass modes, and band pass filtering, this module packs a lot of tone shaping into 14hp.

Patch notes:
Green dots show approximate pot and switch positions. Where a pot has two dots, this illustrates the range I move them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
I'm using the VCA as a mixer so that I can use the outputs from both the BP and 6dB outputs of the Sonic XV. Notice in the video they are set at different volumes at different points depending on the sound - you will need to adjust this too, as different combinations of IN LEVEL, IN MIX, IN WAVE, and filter settings can make a significant difference to volume levels.
Modules used from left to right: Vintage Transistor Core VCO, Sonic XV, Contour Generators, Discrete Cascaded VCA.

2. Patch of the Week: 'Schulze School' - Melodic Eurorack performance + 'how-to' guide & patch sheet

This week's patch makes use of the V-Shape wave shaper/wave folder to sculpt the great analogue tone of the MiniMod VCO to create some delicate timbres that reminds us of Klaus Schulze's mesmerising sounds created on his sequencer-driven Moog modular synth systems in the 1970's. It also makes particular use of the Ring SM as a sub oscillator generator, and the rich tones of the Sonic XV diode filter.

Check out the AJH Synth playlists for more 'Patch of The Week' videos, which will be either performances or 'how to' guides detailing a range of sounds, some familiar, some less so, and each containing a patch sheet at the end to show you how to construct it for yourself.

3. Patch of the Week: 'Singing Gemini' - Dual Analogue VCF as a Dual Sine Wave VCO How to & patch sheet

This patch uses each of the 2 analogue filters of the Gemini as a dual VCO, self-oscillating, so that they produce sine waves and can be sequenced melodically using the Korg SQ-1 or any analogue step sequencer. This guide shows you how to make this patch, along with a patch sheet at the end. It is one of the many ways you can use just a couple of Eurorack modules to make music, as modular synthesis can be rewarding even with a minimal gear list.

Patch of The Week: 'Filter Drums' Part 1 - Analogue Cowbell w/ Fixed Filter Bank 914 (& VCF Clave)

video upload by AJH Synth Official

"This week's patch is the first of a short series showing ways to use filters for vintage rhythm/drum machine percussion style sounds, beginning with an analogue cowbell-type sound using the Fixed Filter Bank 914.

00:00 Patch of The Week: 'Filter Drums'
02:07 Patch Sheet

Some filters can be used to create tones without any input sound, simply by pushing them into self-oscillation (raising resonance beyond it's threshold point), but the Fixed Filter Bank is not a regular filter/VCF, so it works a little differently. Rather than controlling the overall frequency of the filter, each of it's bandpass filters has a preset frequency, for which you control the level. On the AJH Synth module they are deliberately tuned to one of two pitches when pushed into feedback, which makes it more musically useful. Here, I mix in some white noise to add texture to the feedback frequencies.

For comparison, I also included the Ladder Filter here to demonstate how a typical VCF (which can self-oscillate) can be controlled by a sequencer, with the steps controlling the pitches it produces. The point is that either module has it's advantages when used to synthesize particular sounds. In this video the ladder filter is producing simple tuned claves."

Patch of The Week: No-Input Filter Drums Part 2 - Using VCF Self-Oscillation to create Percussion

video upload by AJH Synth Official

"This week's patch shows some ideas for using self-oscillating analogue filters to produce vintage drum machine inspired sounds, the basis of which can be used to emulate such sounds as the clave, bongo, cowbell, and kick/bass drum of early rhythm boxes. I used the sounds of the Roland CR-78, TR-77 and Acetone FR-2L as inspiration here, but in a later Patch of The Week video I'll be recreating some sounds of 70's machines more directly, using VCOs and noise sources. In the meantime, the methods contained here might be of interest to those wanting to make some simple percussive accompaniment with a limited number of modules. At the end of the video I'll show some vintage-inspired patterns using the modular as a 4 voice drum machine, without needing to use samples or a sampler.

Patch of The Week: Blade Runner / Vangelis CS-80 Sounds - Gemini Trilogy Part 3

video upload by AJH Synth Official

AJH Synth Official Patch of The Week series

"3 Variations of a patch based on the sounds from the original 1982 Blade Runner movie, which were originally created on a Yamaha CS-80 by the composer Vangelis. This version uses a monophonic setup with the AJH Synth Gemini 2412 dual VCF.

This is Part 3, see Part 1 & 2 of this series featuring the Gemini - Part 2 features brass sounds, partly derived from this patch, but loosely inspired by Jean-Michel Jarre (Oxygene) and other 1970's-80's sounds. Part 1 features a simple performance bringing versions of the sounds from both parts 2 & 3 together.

The CS-80 was fully polyphonic, and has remained hugely expensive to this day. It used two 'channels' per voice, each being a complete 2-VCO synth voice in itself, with both a high pass and low pass filter in series (HP into LP). It's known for having an exceptionally bright sound, which is difficult to match.

The Gemini 2412 is a dual multi-mode filter, each having low pass, band pass, high pass, and variable LP/HP, along with Dual (both filters mixed in parallel) and Cascade modes (first filter into second filter). Both filters are connected to a voltage-controlled cross-fader, or can be used as 2 entirely separate VCF's. It's based on the VCF from the original Oberheim SEM module, but also has a high-resonance option selectable by jumpers of the rear of the module, which is capable self-oscillation.

How to use Gated Slew with a Sequencer - Gate signals explained + Sample Hold & Slew module tips

video upload by AJH Synth Official

"Slew allows you to slide/glide between notes in a sequence, like those famous TB-303 Acid House tracks and a whole range of other electronic music styles, but if it's not built into your synthesizer it might be confusing how to achieve it, particularly as there are so many sequencer options available, many of which function differently from each other. This video shows how 3 popular desktop step-sequencers can work with the Sample Hold & Slew module - the Doepfer Dark Time, Korg SQ-1, which are both akin to vintage analogue step sequencers, and the Arturia Beatstep, which functions more like a Roland SH-101. I used just one MiniMod VCO going into the Sonic XV Diode Ladder Filter, since the TB-303 also has a diode ladder VCF, and here I've used it in just 6dB mode for extra squelch! However, I'm also using the Sonic XV's built-in wave folder to significantly change the timbre of the incoming triangle wave. The Sample Hold & Slew can function as a separate gated slew module, with selection of up or down slew only, whilst the sample & hold part of it can be used independently, serving as 2 individual modules in 1. Or both functions can be combined, so that random voltages can slide from one to the next, even at very slow speeds, which is great for modulating gradually evolving drone sounds. The Colour and Restrict controls can be used to fine-tune a more desirable range of random frequencies from the noise source. An external clock can be used to sync the random voltages with other modules, sequencers or keyboard gates.

Additionally, audio can be passed through it to use as a noise source for the sample & hold or track & hold. At high clock speeds this feature can be used a very lo-fi bit-crusher, and slowing the rate down will gradually mangle the audio further, eventually reducing it to random beeps!

Performance: Destination Not Berlin - All-analogue Melodic Set using AJH Synth Eurorack Modular rig.

video upload by AJH Synth Official

"This live melodic modular set by 'tomorrow the cure' was originally intended for Superbooth 22 in Berlin, but had to be cancelled due to hearing problems. Since the set was ready to go I thought I'd record it to share with you as another example of what a Mini Mod system can do, and what it can sound like. If this appeals to people there'll be more performance videos in the future, showing AJH Synth modules being used as they're intended - to make music. Hopefully these videos will be an inspiration to people, and compliment the 'User guides' and 'Patch of The Week' videos, which will continue to serve as more practical, or instructional videos.

I've dedicated this performance to Klaus Schulze, who passed away recently. His approach to making music and the sounds he created were a great influence of mine personally. Since then Vangelis has also passed. Fortunately we will always have the gift of their music, both to listen to, and be inspired by.

Performance breakdown:
The synth rig used is based around two voices from just 3 VCO's, 1 of which is paired with a Ring SM, which serves as a waveform mixer, and provides a -1 sub-octave. This then feeds the Gemini 2412 filter, whilst the VCO's triangle goes to the Sonic XV for processing by it's wave folder. All of this is mixed in the Muting Mixer & VCA on the top row. This is responsible for the melodic notes and sequence of the first 8 minutes, the drone in the following section, and then the final sequence.

The other 2 VCO's are going to the Ladder Filter, or the Wave Swarm, which is then passed to both the Ladder Filter and the Fixed Filter Bank 914. These are mixed in the middle row's VCA, and the intervals between the pitch of the 2 VCA's in controlled by the Precision Voltages module. This provides the drone in the first 8 minutes, the played notes/chords thereafter, and the choir-like drone during the final section.

Through the sequencer I switch the keyboard control from one voice to the other. I edited out the re-patching between parts to shorten the video - I took my time over the process as my hearing was still not 100%.

Tracks in this performance:
00:00 Intro
00:31 Part 1 - Opening piece
02:15 Part 2 - 'Monotherapy' from 'Grey Days & Old Ways', 2019
07:47 Part 3 - 'Miserere' from 'Two Voices', 2022
17:33 Part 4 - Untitled...
Parts 2 & 3 are available at https://tomorrowthecure.bandcamp.com

'Two Voices' was recorded entirely using the AJH Synth Mini Mod system - the same modules used in this performance. As was 'One System', and the majority of both 'Grey Days...' and 'Lost Soundtracks'."

Shine On You Crazy Diamond - A Pink Floyd classic Minimoog lead sound recreated on a MiniMod system

video upload by AJH Synth Official

"How to guide with Patch Sheets: An interpretation of the classic lead sound from the intro to Pink Floyd's 'Shine On You Crazy Diamond Part 1', which is believed to have been recorded using the Minimoog synthesizer. The AJH Synth Mini Mod system is a Eurorack modular recreation of this classic analogue synth, and in this video just the modules from the standard Mini Mod system are used to create the lead sound. An additional, simple background drone is created using another system, comprising 3 VCOs, Wave Swarm, Ring SM and Sonic XV Diode Ladder Wave filter.

------------------------
LEAD SOUND
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
This patch uses only the modules contained within a standard MiniMod voice, which is the equivalent of a Minimoog, simply for a little more authenticity, as this is the synth that was believed to be used on the original Pink Floyd recording. The version here is our interpretation of it, and not intended to be an exact match, so opinions will differ as to the setting used, but we feel it's pretty close. For example, it's possible the Minimoog's MOD MIX control was used on the original to mix VCO 3 and Noise modulation to affect the pitch and filter, but here it would require an additional module to mix both signals, and simply adding Noise as audio sounds very similar, whilst allowing greater control of both.

'A Space Odyssey' with the LUNAR MODULE - Performance with lo-fi sample processing in eurorack

video upload by AJH Synth Official

"This week's Patch of The Week was inspired by the movie '2001: A Space Odyssey', and uses the LUNAR MODULE by AJH Synth to process audio samples from the film, whilst various other Eurorack modules build the accompanying melodic drone to provide the musical backing.

The Lunar Module is an audio processor and noise generator, which also features distortion, a bit-reduction/bit-crushing effect, and a recreation of the 'Quindar' sounds (beeps) used in the actual NASA Apollo space program/missions of the 1960's to early 70's. In conjunction with the Lunar Module's other sound processing tools this can be used to simulate the lo-fi audio transmissions of the time and then applied to anything. All the features are also useful individually, from a customisable noise source, to adding distortion and bit-reduction to any incoming audio or Eurorack level signals, even melodic sounds. This performance originally appeared at the end of the Lunar Module User Guide video - check it out for all the details on what it can do and how to use it.

Lunar Module User Guide - Vintage Space Mission Audio/Mic/Sample/Synth Effects for Eurorack

video upload by

"The Lunar Module is a fun Eurorack module for recreating the sound character of early space missions, or adding noise and bandwidth limitation to mics, line-level audio, samples, and synth modules. It's effects can be triggered manually, or from gate signals, and include noise with colour control (a bipolar low pass and high pass filter), hum effects with frequency control, variable distortion, and 'Quindar' - an authentic beep used at the beginning and end of transmissions from the Apollo space capsule back to the NASA Huston control centre.

As with all AJH Synth modules, the Lunar Module is designed to be played, and it's pots and jack sockets are made easily accessible so that live tweaking is not hindered, and controls are all substantial in size and spacing. Most are based on vintage synthesizer circuits and designs, bringing the sounds, behaviour and character of classic synths to Eurorack modular, but with the advantage of modern reliability, compatibility, flexibility, and understanding of the needs of modern musicians.

Patch of the Week: TRIPLE CROSS - Voltage Controlled Sound Switching with a Step Sequencer

video upload by AJH Synth Official

"The Triple Cross crossfader/panner module from AJH Synth & Tone Science makes a lot of things possible. Here it is being used as a voltage-controlled switch, to change between 4 incoming sounds, and send the chosen sound to its output. This means it can serve as a very convenient method of changing between multiple sounds, perhaps in a live performance, moving between different patches manually using the sturdy, tweaking-friendly controls. However, this behaviour can also be controlled by CV, so the process can be automated, and controlled by other modules, keyboards and sequencers.
In this patch a 4-channel/track step sequencer is being used - the excellent Erica Synths Black Sequencer. One sequencer track is used to send a melody to the VCOs and Gates to trigger the envelope generator. The other 3 tracks are controlling the 3 channels of the Triple Cross, to pan the Fade control hard left or right, like junctions on a railway track, so that the exact sound of our choosing arrives at the module's output, precisely when we want it.
Various combinations of the 3 VCOs, white noise, sub-octaves/sub-basses from the Ring SM, and animated sawtooths from the Wave Swarm are sent to 4 separate filters: The Transistor Ladder Filter, Sonic XV Diode filter, and both filters of the Gemini 2412 Dual VCF. A single Dual Contour Generator is controlling the VCA level, and the frequency of all 4 VCFs. The Sonic XV is also using its wave folder to generate a more unusual timbre from just a single triangle wave. The Triple Cross is a collaboration between AJH Synth and Ian Boddy of the Tone Science record label. It is an exceptionally useful module, being suitable for use with both audio, and control voltages, since it is DC-coupled. More videos featuring this, and other modules in the future.

'Classic Flute' - How to create a more realistic all-analog patch than Classic vintage preset synths

video upload by AJH Synth Official

"A more realistic flute patch than you'll find on classic vintage synths, showing how it's possible to attain a more convincing recreation of an acoustic sound with modular synths, and without the need for samples or digital modules. A truly realistic flute is too much of a tall order - a greater amount of modules, and a more complex controller, would no doubt get you nearer, but here is a more modest way of achieving a reasonable, and nice-sounding impersonation.
Some of the early self-contained synths of the 1970's tried to make useable impersonations of 'real', acoustic or familiar instruments using easily-selectable presets with a very simple voice architecture. Some sounded better than others, but whilst they were often sonically appealing in their own right, they were seldom anywhere near realistic. Among the more famous were the ARP Pro Soloist, Roland SH1000/SH2000, and the Korg 700/700S - all of which very characterful and unique instruments, with their own strengths, and much loved to this day. This patch is a nod to those classic synths, but also exploring what is possible now with modest amount of purely analogue Eurorack modules.

NOTES
_______
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions. Multiple cables may branch from one output to different destinations, so here a multiple should be used.
This patch needs a lot of fine-tuning, so precise pot positions cannot possibly be illustrated, but this should serve as a starting point, from where further experimentation should be applied. The video tries to explain what is happening with the core modules, which should make it easier to understand what needs fine-tuning.
KEYBOARD: Here the controller's MOD output is used to send Aftertouch, but alternatively Velocity, or direct control from the MOD wheel/strip could be sent to the Dual LFO's CV input instead, depending on your controller and personal preference. In the video I also used the Glide module as 'slew' to soften the harsh changes in aftertouch CV from this particular controller, which may not be needed on others.
TAP TEMPO LFO: Because the base tempo is selectable by tap, the rate of the LFO will have to be set by ear.
VCO: If you don't wish to use the envelope to affect PWM, then PWM SHAPE will need to be set just below -1 - the envelope makes a subtle difference here, changing the shape of the VCO's sound slightly.
NEXT PHASE: This is optional, as the noise is heard subtly in this patch, and only becomes more apparent when the AUDIO MIX of the Gemini is in favour of VCF1 (noise) rather than VCF2 (VCO), but to my ears it makes the sound of the noise more similar (see video description).
GEMINI 2412: I'm using the 'high resonance' setting on VCF1. which is set by the rear jumper, or optionally using the Gain Switch (see User Guide video or manual on the website. Without it the resonance will need to be set to maximum, but still might not be quite enough.
Modules used from top-left to bottom-right: Glide + Noise, Vintage Transistor Core VCO, Contour Generators, V-Scale, Tap Tempo VC-LFO, Next Phase, Gemini 2412, Discrete Cascaded VCA.

Patch of the Week: Whistle Lead (Tomita/Tangerine Dream) Using self-oscillating Filter/VCF as a VCO

video upload by AJH Synth Official

"This sound is inspired by lead sounds of the 70's/80's from Isao Tomita and Tangerine Dream (Remote Viewing), but will also be reminiscent of Kate Bush's 'All we ever wanted', and even Jeff Wayne's 'War of The Worlds' musical. It uses a filter/VCF in self-oscillation as a VCO, controlling it melodically, with envelopes and noise to help recreate the sounds. No VCO/oscillator is needed in the patch, and white or pink noise is optional, but necessary to get a Tomita-like whistle sound. Tomita originally used a Moog modular system for these sounds, so given that the AJH Synth MiniMod system and it's Transistor Ladder Filter are directly based on the early R.A.Moog version of the Minimoog, it's possible to get very close to such sounds. However, I've not tried to emulate it exactly, but you can see that the basis for this patch is very easily customisable, so it's a very useful synth patch to understand for a variety of musical applications.

Patch Notes:
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
This is based on the version in the video with noise mixed in as audio, and glide applied to the keyboard CV. For variations without noise or glide, and usage with a mod controller, see the appropriate part of the video (check Index). Only a couple of connections need to be changed for these purposes.
V-Scale: Used here as a simple multiple, but since it's handling Gate signals any passive multiple could be used.
DH-ADSR: Another Contour Generators could be used instead, but the advantage with the DH-ADSR is independent control of both Decay and Release, meaning greater control. It serves as a great companion to the Contour Generators for this reason.
Dual LFO: The Tap Tempo VC-LFO module could also be used here in the same way, as it also has a built-in VCA (level control).
Ladder Filter: The Gemini 2412 would also work well here, it's tracking in self-oscillation is actually better overall. It would just need to have high resonance/self-oscillation enabled by the rear jumpers (see online manual or video user guide). The Ladder Filter struggles to track at lower frequencies, this is an authentic characteristic of the original Minimoog filter, but it's fine for the pitch/note ranges used in this video. The Sonic XV will also self-oscillate, but it's ability to track 1V/Oct is not as tight as the Gemini.
Modules used from left to right: Glide + Noise (Mk I or Mk II), V-Scale, DH-ADSR Envelope, Dual LFO + VCA, Contour Generators, Transistor Ladder Filter, Discrete Cascaded VCA."

AJH NEW MODULE! 'CHANCE DELAY' Voltage-Controlled Probability/Random Gate Delay and More

video upload by AJH Synth Official

"The Tone Science Chance Delay is a unique concept in Eurorack modules that combines chance and randomness, with pulse delay and pulse conditioning. It is a collaboration between between electronic musician/composer Ian Boddy and AJH Synth. It can perform as a Chance generator, but is also capable of pulse stretching for Trigger to Gate conversion, pulse shortening for Gate to Trigger conversion, Gate Delay, Sub Bass Generation and also "divide by n" clock division. There is a wide range of control and all functions can be operated manually from the front panel or can be automated using external CV voltages. Chance can range between 0 to 100%. The Gate out can be delayed by anywhere between from 0.5mS to 30 Seconds, and the output Pulse length can also vary from 0.5mS to 30 Seconds. The TRIG push button allows manual triggering of pulses, also determined by the Chance control, and a green LED shows the output pulse status. It includes a handy "Gate pass through" mode; when the Length control is set to zero the incoming pulse or trigger will still be determined by the Chance and Delay controls, whilst the outgoing gate length will be the same as the incoming gate length. Its compact 8hp form factor and very low power consumption make this an excellent addition to any Eurorack system.

"A rather gentle 2-Voice, all-analog melodic performance using random arp mode on a Keystep Pro, whilst controlling a 2-note drone sound with the keyboard. This time a slightly simpler version of this recording: [below]

The system includes three Vintage Transistor Core VCOs and noise from the Glide + Noise module, which are split between the two filters of the Gemini 2412 dual multi-mode VCF. Two of the VCO sawtooth waves go to the Wave Swarm , which thickens them, creating the effect of many stacked saws (or supersaw) buzzing as their waveform timings collide. This makes an excellent basis for drone sounds, even from a single VCO.

Other important modules here are the Tap Tempo Voltage-controlled LFO, which is clocked by the arp (gate out to clock in), and modulates/varies the frequency of the filter on each new arpeggio note, creating more movement. Also the Ring SM adds a -1 sub-octave to the single VCO of the arpeggio, and mixes in some white noise, fattening the sound hugely.

'Not moving on' - Mellow, Melodic Eurorack Performance (AJH Synth MiniMod & Gemini 2412)
video upload by DreamsOfWires

"Melodic real-time performance using 2 modular analogue synth voices, a work-in-progress version for this album: https://tomorrowthecure.bandcamp.com/... [posted here w/ video]

This track makes particular use of the Gemini VCF as two seperate filters - the melodic part (an arpeggio from the Keystep in random mode) consists of either the Entropic Doom (alone as a pitched noise VCO, sometimes with a regular VCO mixed into it's audio input, or used as a sync source), or just the standard VCO through the Ring SM (where additional octaves are added). The output of both the Entropic Doom and the Ring SM go to independent filters on the Gemini, Low Pass and Band Pass respectively. Then, the keyboard/sequencer gate from the Keystep triggers the Sample & Hold module, which modulates the mix between the output of these two filters using the Gemini's built-in voltage controlled mixer/cross-fader. I'm also using the CV Mix module to set the modulation level, range, and start/end positions.
The drone sound is two VCOs going through the Wave Swarm to the Ladder Filter, at certain points I manually shift the pitch of one of the VCOs using the Precision Voltages module, via the Glide module (up only). Recorded into AUM on an iPad with EOS2 reverb.
Added video footage is of the North Norfolk Railway, then the Mid Norfolk Railway, UK (before 'lockdown')."

'Pan Flute' - How to make this movie-inspired, all-analog Synth Patch in Eurorack Modular

video upload by AJH Synth Official

"This was loosely inspired by the 'pan flute' sound from the film 'Aguirre: Wrath of God', and uses a single VCO, white noise, and envelope-controlled filtering to simulate the pipe and breath elements that form the sound. Fixed Filter Bank sculpts the noise, removing low frequencies and pushing selected highs, before being mixed into the Sonic XV's bandpass filter along with the square wave from the VCO. Importantly, the FFB's wet/dry mix is also controlled by an envelope here, a rare feature on a filter bank. Pulse width modulation from red noise ads a subtle distortion to the oscillator, and the VCA in the Dual LFO is used to ad optional pitch vibrato and VCF frequency modulation.

Aside from the flute scene (see link in video), the movie soundtrack was mostly the brilliant work of Popul Vuh, and makes the official album release worth listening to regardless of the movie, with memorable use of Mellotron. However, the Werner Herzog movie itself is equally brilliant and memorable, a captivating, immersive experience to watch, made on an unimaginably small budget, yet a direct influence on Coppola's 'Apocalypse Now' a few years later.

PATCH NOTES:
------------------------
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions. Multiple cables may branch to different destinations, this is where some form of multiple should be used.
This patch needs a lot of fine-tuning, so precise pot positions cannot possibly be illustrated, but this should serve as a starting point, from where further experimentation should be applied. The video tries to explain what is happening with the core modules, which should make it easier to understand what needs fine-tuning.
KEYBOARD: Here the controller's MOD output is used to send Aftertouch, but alternatively Velocity, or direct control from the MOD wheel/strip could be sent to the Dual LFO's CV input instead, depending on your controller and personal preference. DUAL LFO: Output goes directly to EXP-CV of the VCO, and IN 1 of the CV MIX.
CV MIX: This module is used here to combine the CV from the LFO and Contour Generator 1, then to fine-tune it, before sending to Sonic XV and Fixed Filter Bank.
FIXED FILTER BANK 914: The IN 2 pot needs to be at zero - this sets the Dry level to zero if nothing is connected to the IN 2 socket, so that when the envelope changes the Wet/Dry level it is in fact affecting the output level of the module, as only a varying portion of the Wet signal is then sent to the Muting Mixer.
Modules used from top-left to bottom-right: Glide + Noise, Vintage Transistor Core VCO, Sonic XV, Contour Generators, Discrete Cascaded VCA, Dual LFO + VCA, CV Mix, Muting Mixer, Fixed Filter Bank 914."

'Sonic X-Voice' - Human Vocal Patch from our Klaus Schulze Tribute video with Sonic XV Eurorack VCF

video upload by AJH Synth Official

"This Patch of The Week shows how the vocal sound was created that featured in the Klaus Schulze tribute video. It uses the Sonic XV Diode Transistor Ladder Filter for both it's band pass filter, and it's built-in wave folder. Patch sheet at the end of video, plus a download link for a PDF version with notes further down the page. Musical Tribute to Klaus Schulze: https://youtu.be/VA-Io4jVKbA

The Sonic XV is a surprisingly flexible multimode VCF - it can do the kind of aggressive, screaming resonance chaos that you'd expect from some of the famous diode filter-wielding synths of the past, but it's also particularly good at softer, delicate sounds, and having a well-featured wave folder on board gives it a much wider scope for tone-shaping. This, coupled with it's fast response, and simultaneous band pass, 6dB and 24dB low pass outputs, makes it a great choice for fast melodic sequences and percussion sounds. It's character is significantly different than that of the Minimoog-based Transistor Ladder Filter, and compliments it nicely, even if only used for it's wave folder to feed other VCF's.

Patch notes:
--------------------
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
DH-ADSR: As we are using the inverted output here, it will constantly be sending a +8V signal to the LIN-CV of the VCO (therefore raising it's frequency/pitch) until it receives a gate signal, at which point it will follow the envelope settings, starting from an output of 0V. This is why the VCO will need re-tuning to match other instruments used, but preferably after you are happy with the amount of envelope to pitch influence you have dialled in. Dual LFO: The Tap Tempo VC-LFO module could also be used here in the same way, as it also has a built-in VCA (level control). Sonic XV: Small differences in wave folder settings can make a big difference to the sound, so it'll probably require some fine-tweaking to get the ideal timbre. I have added some resonance in this version, as it can help to simulate the tone of a human voice, but this is of course subjective - all voices are different. Band pass is definitely the best filter type to use, as it can remove both high and low frequencies that would be beyond those produced by a human voice. Modules used from left to right: DH-ADSR Envelope, Dual LFO + VCA, Vintage Transistor Core VCO, Sonic XV Diode Filter, Contour Generators, Discrete Cascaded VCA."

Per-step Pitch Intervals with a Sequencer using PRECISION VOLTAGES module for Eurorack

video upload by AJH Synth Official

"Using a step sequencer to change VCO pitch per step: The Precision Voltages is a convenient way to offset VCO frequencies musically, by pitch increments of semitones and octaves, which can be either added to, or subtracted from an incoming CV signal, such as a sequencer or keyboard controller. This can have many uses, not just for melodic control of oscillators, but here is a particularly useful function for pattern-based pitch sequencing.
Modules connected to the outputs of the Precision Voltages will be sent fixed voltages of preset musical intervals, based on the 1V/Oct scale. These voltages, here represented as precise intervals of semitones and octaves, are selected by the two rotary switches. With no external CV signal connected to the inputs, the module will function as a source of preset fixed voltages, with a huge range of +11 volts to -11 volts (10 octaves + 12 semitones). These can be conveniently switched on or off with the A & B switches. When an incoming CV signal is present, this voltage sources is added to, or subtracted from the signal, meaning it can be used to easily shift the pitch, frequency, or CV level of modules it is connected to. This is ideal for shifting the pitch of VCO's to create harmonies or simple chords, or for offsetting CV levels in any application that uses them.
The Gate input of this module affects the value of A only, and will allow it to be turned on with a high gate signal, or off when the gate is low. B will remain unaffected, and will continue to output the pitch/voltage offset selected by the rotary pots and switches. The 'OUT' output will combine both A and B, depending on the switch position next to it. As a result, when A is turned off, either by the switch or a gate signal, then only the value of B will be output here.
Official website page: https://ajhsynth.com/Precision.html

I'm also using the new Chance Delay module on this patch for some generative randomness/probability - it's not necessary, the sequencer can be connected directly to the Precision Voltages Gate input.

SEQUENCER ADVICE: Most sequencers will allow you to change gate length, sometimes referred to as 'duty', as is done in this video, but you'll need to consult your sequencer's documentation if you are not familiar with how to do this. On many it is obvious, but others not so much. Also, some will allow you to change the gate length directly and quite precisely, whilst others will only allow you to change it in fractions or percentages. This may mean that you can't quite get the gate to span the entire step length, meaning that the pitch modification made by the Precision Voltages may be heard ending prematurely. This is the behaviour of the sequencer, not the module. However, there is a way around this...
A gate signal is just a voltage of either zero volts (off/gate is low), or a minimum of +5 volts (on/gate is high). Gates are pulse (square) waves for this reason, as they are simply one of these two states, and so some sequencers will also refer to gate length as 'pulse width'.
However, all the gate input needs is one of these two voltage values to turn it on or off. This means the CV outputs of a sequencer can also be used, so long as your sequencer has a range of at least zero to +5 volts, which they almost certainly will. Therefore if you connect the CV output of the sequencer to the Gate input of the precision voltages, set all of the step pitches (or pots such as on the SQ1 used here) to zero, when you run the sequencer the pitch changes set by the Precision Voltages will not be activated. If you then raise the pitch of a step to maximum, it will activate the pitch change on that step. Problem solved!
This is not as immediate or convenient as being able to switch the changes on or off with buttons, but it works just the same otherwise, and may be helpful if you can't get satisfactory results with your sequencer, or are finding it too difficult to adjust the gate lengths accurately.

Patch of The Week: 'On the Run' Ep2 Percussion - Floyd's Classic Synthi track recreated in Eurorack

video upload by AJH Synth Official

"Second of 2 videos showing how to recreate the classic Pink Floyd track from 'Dark Side of The Moon', originally recorded on an EMS Synthi AKS. This episode covers the percussion element of the sound, which in the original album recording was simultaneously created and performed along with the melody on the Synthi AKS. Effectively, the Synthi was used to create 2 voices from one monophonic synth by some clever use of the instrument's built-in ring modulator.
Episode 1 covered the melodic sequence, how to programme it, and how to get a similar sound. Check it out here: [posted here]
In this version I'm using the RING SM, as it's ring mod is directly based on the one in the EMS Synthi and VCS3, so it's behaviour is the same. This trick will not work on all ring mods, as they vary in design and the way in which they achieve a ring modulation effect. However, the Ring's SM's is a true, all-analogue ring modulator.
I start using white noise from the GLIDE + NOISE module, and then experiment using the ENTROPIC DOOM and LUNAR MODULE as the noise source. CV sequencing is supplied by the Arturia Keystep sequencer.

Patch Notes:
Green dots show approximate pot and switch positions. Those with two dots show the range I adjust them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
SONIC XV: This gets us fairly close to the Synthi's sound, as that instrument also used a diode ladder VCF. I use both 24dB, as the original Synthi filter was 24dB, but also the 6dB output, because in 24dB it is easier to send the filter into self-oscillation when using high resonance, and this sound really benefits from a lot of resonance. The 6dB can achieve a more noticeable degree of resonance before self-oscillation occurs. It is subjective, and both have their character and strengths, so experiment!
RING SM: Firstly, depending on what you are using as a noise source you may need to keep levels low, both on the RING SM and the VCA. Here I'm using white noise from the GLIDE + NOISE module, which has a low volume level, but when using filtered noise from the Entropic Doom (for example) the output will be quite high. Therefore, regardless of your noise source, start low, and gradually raise the levels to a useful volume.
DISCRETE CASCADED VCA: Either this or the MUTING MIXER & VCA can be used, as I did in the previous video. All that's important here is having at least two channels - one for filter output and one for ring mod output, so that the mix/volume balance between the two sounds can be adjusted, and then just to be careful of high audio levels.

Patch of The Week: Brass & Blade - inspired by Vangelis & Jarre, a melodic jam with 2 patches

video upload by AJH Synth Official

"First of 3 videos with the Gemini 2412, starting with this simple performance using 2 sounds derived from a monophonic synth brass patch, loosely inspired by Vangelis (Blade Runner) and Jean-Michel Jarre (specifically Oxygene). The next 2 videos will show you how to make the sounds.
The patch emulates the Oberheim SEM design (2 VCO, 1 VCF, 2 ADS envelopes), as the Gemini 2412 is based on the filter from that classic gorgeous-sounding synth module. As many will know, Vangelis famously used the CS-80, and Jarre a variety of expensive early synths, but the humble SEM wasn't necessarily associated with either of them. However, it's character of sound, and that of the Gemini, make it a particularly good choice for brass-like pads and leads, either using it's bandpass filter (as in this video), or it's high pass and low pass filters (much like the CS-80).
In the next video I'll show how to construct the brass sound from the later half of this video, and in the video following that will show how to make a couple of sounds directly based on the CS-80 patches used in Blade Runner, so stay tuned.

Polyphonic: Using the Keystep Pro for 4-Voice Polyphony in Eurorack Modular - with AJH Synth MiniMod

video upload by AJH Synth Official

"This video demonstrates the Arturia Keystep Pro controlling a MiniMod system in polyphonic mode, and show's how to enable up to 4 voices of polyphony on the Keystep Pro controller keyboard. The MiniMod system uses just 4 VCO's, envelope generators, VCF's and VCA's to supply 4 simple, single-oscillator voices, which are then complimented by either an LFO or noise source to add interest to the sound. This really is about as spartan as you can get for a modular 4-voice setup, so adding further modules would greatly expand it's sound palette, but this is just a proof of concept. Since it's fully modular, even with such a simple voice structure a surprising range of sounds can be achieved.

This was partly inspired by the earliest polyphonic synths, which were initially huge modular systems controlled by polyphonic keyboard controllers, and then the first polyphonic Oberheim synths, which controlled 4 or 8 individual monophonic synth voice modules individually (the superb-sounding SEM), each needing to be setup and tuned. However, this meant that each voice was free to be whatever the user wanted - similar or completely different than the others, something conventional analogue polysynths can't do.

The Gemini 2412 is used here as it has extensive multi-mode filter options, and conveniently contains 2 fully-featured VCF's per module, but also since it is directly based on the filter from the classic SEM module. A pair of Contour Generators serves as a simple and convenient dual envelope per module, although here they are shared for both VCF and/or VCA.
It's unlikely that many would buy a complete modular system purely to use as a polyphonic synth, but as your system grows it may eventually provide sufficient modules to be used in a poly configuration, even just as 2 voices, such as here: [posted here]

POWER: This module setup and PSU is just an example of the concept - it isn't necessary to arrange the modules in this way, and you should always ensure your power supply is sufficient to provide significantly more power to your selection of modules than is needed, across the +12V, -12V, and 5V power lines. For example, in this setup I'm using roughly 400mA on the -12V rail, but the PSU only provides 500mA to -12V, so this is pushing it a little too close to the limit than is ideal. Modulargrid.net is a great tool to use for designing your system and calculating your power needs, but also consult your PSU's documentation for advice on power usage.

MODULES USED:
Vintage Transistor Core VCO x4
Gemini 2412 x2
Contour Generators x2

MiniMod Keyz: 1 Synth, 1 Pattern, 10 Minutes - Berlin School-inspired one-synth improvisation

video upload by AJH Synth Official

"This was an early run with our MiniMod Keyz prototype test machine, using just the onboard arpeggiator, voiced by 3 VCOs, Ring SM, Transistor Ladder Filter and more. This system is superb at recreating the sounds and vibes of those early electronica records of the 1970's, providing the sound of the Minimoog and the flexibility of the Moog modular systems that dominated them. As the author of this video I could quite honestly sit for over an hour making sounds such as this on just one sequencer pattern or arpeggio, it just sounds that good. Of course, the system isn't trapped in the music of the past, it's a fully-modular Eurorack system after all, but when it comes to the vintage electronic sounds and tones that brought this musician to the world of analogue synths in the first place, the MiniMod sure does deliver the goods.

AJH Synth Patch of The Week: Lo-Fi Claps - all-analogue crowd clap sound

video upload by AJH Synth Official

"Rather than copying the way many vintage drum machines tackled their 'clap' sounds, here is a simple, yet more organic take on it. Some of the most famous analogue claps were achieved by using a series of very fast envelopes to control the amplitude (VCA), simulating the effect of multiple hands clapping simultaneously, along with their imperfect timing (humans aren't the most accurate drum machines). However, using fast, random modulation instead of a repeating envelope creates a more natural effect, and a simple noise source can provide this, and with longer envelope decay times it can produce an effect more akin to a large crowd clapping. Pink noise is especially suited to this, as it's lower frequency (speed) will have more audible results. White noise is still used as the audio source for the sound itself, and a bandpass filter is used as it will allow a more appropriate range of frequencies to form the timbre of the sound than lowpass filtering. Resonance is also important in forming the shape of the sound. The VCF I've chosen for this example is the Sonic XV Diode Transistor Ladder Filter. Patch Notes and PDF link further down the page.

Expanding the Mother 32 - Sub-octaves, wave multipliers & extra VCO's for chords & vintage fatness

video upload by AJH Synth Official

"Here are some ideas for expanding the sonic possibilities and fattening up the sound of the Moog Mother 32 analogue synth - We're sometimes contacted by customers who have, or want to add AJH Synth modules to theirs, as the Mother 32 has great connectivity for Eurorack integration, so hopefully this will video will show a little of what is possible. The Mother 32 has a single oscillator, so the most obvious choice would be to add more VCO's, in order to perform harmonies and simple chords, but also it doesn't have a sub-bass, or sub-octave generator, so this may also be worth considering. In this video we demonstrate both of these options, using the MiniMod Vintage Transistor Core VCO's, the Ring SM to generate sub-octaves and as a CP3 style mixer, but also the Wave Swarm to simulate multiple stacked sawtooth waves. We also use the Sample Hold & Slew to generate rhythmic, random filter modulation, the Precision Voltages as a convenient way to select precise octave and semitone pitch changes of VCO's, and use the V-Scale to address 1V/Oct scaling/tracking issues that may occur when using the Mother 32 to control external VCO's or other instruments via CV.
