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.

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.

"It's great to announce my second Eurorack module design, the Chance Delay, in conjunction with AJHSynth. Launching under the Tone Science brand this 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 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.

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.

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%.

00:31 Part 1 - Opening piece
02:15 Part 2 - 'Monotherapy' from 'Grey Days & Old Ways', 2019

AJH Synth Introduces 2HP Voltage-controlled High Pass Filter

NEW MODULE! Low Fat - 2HP Voltage-controlled High Pass Filter - Features, Examples & User Guide
video upload by AJH Synth Official

"The LOW FAT is a new 2hp Eurorack module by AJH Synth, it's a High Pass filter, with frequency control by either manual pot, and/or external CV with attenuator. It's intended to compliment other filters, particularly low pass VCF modules, in practical tasks such as removing excessive low frequencies, for example when the bass is swamping a mix. However, because it can be voltage-controlled it can also be used musically as with any other VCF. When used in conjunction with a LP filter it forms a fully customisable band pass filter, allowing the range of passbands to be cherry-picked. This can be particularly useful in creating percussive sounds, such as snares and hats, but also on sequenced bass lines. Since it is only 2HP it's a great way to occupy one of those frustrating gaps in your eurorack modular case with something that is deceptively useful, and adds another dimension to the classic bass monster that is the Transistor Ladder Filter.

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.

'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.

'Arp & Drone' 2-Voice Melodic Eurorack performance (ambient, minimal, all analogue synth sounds)

video upload by AJH Synth Official

"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')."

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.

Vintage Transistor Core VCO x4
Gemini 2412 x2
Contour Generators x2
Discrete Cascaded VCA x4

AJH Synth Modular Sound Demo by @DKS SYNTH LAB (MiniMod Eurorack Modular jam, No Talking)

video upload by AJH Synth Official

"A repost of a video by Daniele Chierichetti demonstrating lead sounds and showing some of the sonic possibilities of an AJH Synth Eurorack modular synth system. The standard MiniMod voice forms the basis of the system featured here, and this voice is directly based on the original R.A.Moog version of the Minimoog, and as such it is capable of the same classic lead sounds, the same warmth, punch, and character. However, because it is modular, it takes this voice way beyond anything it was originally capable of, opening it up to the now huge Eurorack universe, including a wealth of modules by AJH Synth.
These high-end modules are mostly based on classic vintage designs, some of which are very difficult to obtain nowadays, but brought firmly into the modern Eurorack era by a wealth of connectivity, functionality, and reliability, that simply didn't exist 'back in the day'. Also, some modern, digital modulation modules compliment the range, hugely expanding it's sonic scope."

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.

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.

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.

The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

TRIPLE CROSS: How to create Circular/3D Panning effect with this Eurorack Stereo Cross-fader module

video upload by AJH Synth Official

"The new Triple Cross module from AJH Synth & Tone Science is a 3-channel stereo cross-fader/panner, fully voltage controlled, and able to be used for a plethora of different audio or CV duties. Here it is being used to achieve a dual VCA, stereo panning and cross-fading simultaneously, alternately raising and lowering the volume of 1 or 2 incoming audio signals, whilst moving them between left and right outputs. This can be used to create a 3D impression a sound that is moving in a circular motion.
This might more often be useful for creating momentary effects, and could be especially interesting for ambient drones, but here I demonstrate it using a sequencer, and eventually 2 melodic synth voices playing different patterns. An important element in this patch is the modulation - I use the Dual LFO +VCA module to create a quadrature triangle LFO, so I have 2 triangle waves running at the same speed, but at a 25%/1 quadrant difference in their duty cycle. Here it's achieved by using the square wave of one LFO to sync the other.

Mini System 'Berlin School' Performance - 2 Monosynths in 1 Case | AJH Synth Analog Eurorack Modular

video upload by AJH Synth Official

"A demonstration of a modest 6U 84hp Eurorack modular system by AJH Synth, incorporating a 3-VCO MiniMod voice based on the R.A. Moog Minimoog, Gemini 2412 dual VCF based on the Oberheim SEM filter, and a couple of very useful utility modules, particularly the Ring SM. This setup can be used as 2 separate synth voices, demonstrated here in this 'Berlin school- inspired performance.

The complete MiniMod voice is a combination of 7 modules directly based on the first, more sought-after version of the Minimoog, along with it's characteristic behaviours. The Transistor Ladder Filter behaves in the same way, 'Emphasis' (resonance) robbing a little of the low frequencies at higher levels, the Contour Generators having a cumulative/stacking level behaviour when triggered rapidly, and the Discrete Cascaded VCA (also the VCF input levels) driving and distorting the signals when pushed.

Here the MiniMod is used as a 2-voice monosynth, with one of it's VCO's being donated to the lower voice, filtered by the Gemini multi-mode filter. It sounds much bigger than a single VCO voice thanks to the Ring SM. The Ring SM provides a Moog CP3-based 5-channel mixer, a 3-axis analogue ring modulator based on that from the vintage EMS Synthi/VCS3, and particularly useful in this patch - 2 sub-bass generators, providing -1 and -2 sub-octaves to an incoming signal. This produces shaped sine waves, as opposed to more hollow-sounding square waves often used by other synths or modules, so they sound warmer, fuller and fatter.

The Muting Mixer is used as a second VCA here for the Gemini voice. However, it has a 'Distort' feature that emulates the old Minimoog trick of sending the headphone output to the VCF input to create a feedback loop and some additional overdrive/distortion. As a result it can make a good alternative to the Discrete Cascaded VCA, but even the latter can add significant drive to the signal. This module could also be used to simulate the Minimoog's VCO and noise switches, but for 5 signals of your choice, as it features illuminated 'Mute' switches, allowing sound sources to be instantly switched in and out of a patch, and at their own volume levels.

The Dual LFO + VCA is especially useful here, as it gives plenty of modulation, without having to sacrifice a VCO for that purpose. It also has a built-in VCA, allowing it's level to be controlled externally, perhaps with an envelope or Mod wheel for delayed or expression-controlled vibrato.

This rig also has a third envelope in the powerful DH-ADSR, but it's not used in this patch, along with the Precision Voltages, which among other uses allows pitch intervals of 2 VCOs to be controlled accurately and conveniently, selecting between octaves and semitones set by the rotary pots and switches. This is super useful for live performances.

AJH Synth Official GEMINI 2412 User Guide posts

"Part 3 of 3. The AJH Synth Gemini 2412 Dual Multi-mode SEM-based VCF explained. The 3-part User Guide will cover this very complex and fully-featured, yet simple to use analogue filter. This final part shows how the functions explained in parts 1 and 2 can be used with both filters working together, with particular attention to creating a 24dB low pass filter, and a 12dB band pass filter, using the Gemini as a single filter in cascade mode. Also, creating formant, or vocal type sounds, evolving patches using an envelope to morph between the output of both filters, then finishing off with various no-talking patch examples, such as using the Gemini as a stereo filter, as part of a 2-voice polyphonic synth, and constantly changing sequencer patterns."

MiniMod 6U Full System minimal 2-Voice performance - Melodic Eurorack Modular - AJH Synth

video upload by AJH Synth Official

"Another 2-Voice melodic performance using the MiniMod 6U Full System, now available to purchase from https://ajhsynth.com/Minimod.html, pre-installed in a powered case. This time a version of a very minimal track I previously released here (track 6): https://tomorrowthecure.bandcamp.com/...
This is a bit more simplistic than the previous video, but another example of what is possible using just single, modest-sized case, packed with an incredibly flexible, vintage-voiced, fully analogue, Eurorack modular synthesizer. Here the synth is configured as two operate voices - a 2 VCO drone synth generating 2-note chords, and a single VCO lead synth with external delay. It uses all the modules from the Minimoog-based part of the system, along with the Gemini 2412 SEM-based dual VCF, DH-ADSR envelope generator, and the indispensable Ring SM as a CP-3 mixer and sub-octave/sub-bass generator. Also used is the Erica Synths Black Sequencer.

New TAP TEMPO VC-LFO 16-Wave Eurorack Module by AJH Synth

NEW! TAP TEMPO VC-LFO 16-wave voltage-controlled modulation Eurorack module with VCA, Int/Ext clock
video upload by AJH Synth Official

"The TAP TEMPO VC-LFO is a skiff-friendly, 42hp Eurorack low frequency oscillator. It's a modulation powerhouse, with 16 waveforms, 15 with 'wave form twist' PWM-like control, random sample & hold type waves, and CV control over all functions.It can serve as a clock source, or can be clocked by external pulse/gate signals, with a clock multiply/divide function, along with a built-in VCA controlling both bipolar (LFO type) and unipolar (envelope-type) outputs. It's great for everything from simple expression-controlled pitch vibrato, to clocking or being clocked by sequencers for time-synced modulation, and generative patches, where randomness and/or time control is needed to be shared between different modules.

This video is a brief introduction to the module, but following 1 hour after this upload will be a full USER GUIDE VIDEO detailing all functions, along with some example patches.

Every modular system needs modulation sources to add variety and interest to static sounds. The more powerful and versatile the modulator, then the more interesting these sounds can become. We compiled a wish list of useful features, starting with obvious ones such as CV control of Frequency, Tap Tempo, Unipolar and Bipolar outputs and a wide range of waveforms, and then we just kept adding more features such as waveform twist, rate multiplication, Sync In/Out and an inbuilt dual VCA for modulation level control. Then we made sure that we had voltage control (and therefore automation) available for every single feature. This takes it way beyond the realms of regular LFO's and make the Tap Tempo VC-LFO a modulation powerhouse.

Ergonomics are important too, it can really spoil the workflow if we have to stop and refer to the user manual to find out what some obscure control or jack socket does - so it follows our usual format of having a very clear, intuitive and uncluttered front panel. All of the jack sockets are in two rows at the bottom, with the inputs on the left and outputs on the right hand side.

The Tap Tempo VC-LFO is available with either a Black or Silver front panel.

'FAT BASS' - Bigger Sound for Synth Bass Lines using the Wave Swarm & Ring SM Eurorack modules

video upload by AJH Synth Official

"Some fat synth bass line sounds using a variation of 2 VCO, Ladder Filter, Wave Swarm for a thick sawtooth pad, and Ring SM for sub basses. Either or both of these 2 modules add a lot of scope to the sound of even a single VCO, even more so with two. Patch notes at the bottom.
The Wave Swarm uses it's 12 waveform animators to create thick, buzzing supersaw style sounds, from either a single saw wave, or from two independent saws, even as part of two completely separate monophonic synth voices, even a two-voice polyphonic patch. Check the links below for User Guide and some patches.
The Ring SM has both a vintage-voiced, fully analogue ring modulator, modelled on the ring mod from the EMS Synthi and VCS3, but it is also a 5-channel Moog CP3 style mixer, capable of soft clipping overdrive/distortion, and most importantly for bass patches - a sub bass/sub-octave generator, needing only a single VCO to generate both -1 and -2 sub octaves simultaneously. All functions can be used together, or on their own. The sub basses are shaped sine waves, which sound thicker and deeper than plain square waves, which are most commonly used by synths as sub basses.

AJH Synth NEW! MULTI BURST ENVELOPES

NEW! MULTI BURST ENVELOPES - An 8-shape envelope generator, with multiple time-controlled repeats video upload by AJH Synth Official

"An introduction and brief overview of the new MULTI BURST ENVELOPES from AJH Synth." Video by DreamsOfWires

The MiniMod Multi Burst Envelopes module generates variable length bursts of repeating envelopes that can change over time, with CV control of all functions.

The BURSTS control selects a 'Burst Sequence' of between 1 and 40 bursts. The envelope shape of a burst is chosen with the rotary switch, or it can be varied using an external CV, so that it is even possible to chose a different envelope shape for each individual burst in a sequence.

The width of the envelope (i.e. the attack and decay time) is varied with the P-WIDTH control and this can also be CV controlled as a sequence is progressing, so it is possible to vary the envelope speed of each individual envelope burst while a Burst Sequence is running.

The repeat time of individual bursts in a Burst Sequence is set with the LFO Rate control. The LFO rate can be varied with an external CV as a sequence is progressing, so the gap between envelopes can speed up or slow down over time. An external clock can also time the bursts in a burst sequence instead of, or in addition to the internal LFO. Bursts can also be manually incremented with the CLK push button.

The SLOPE control allows Bursts to start quietly and build in level to maximum, or they can start at full level and then reduce in level as the Burst Sequence progresses. In the centre position all Bursts are of equal level.

Full USER GUIDE video available 30 minutes after this video goes live.
