Minimal Jam: Chance Delay & Entropic Doom - random gates, melodic noise, analogue percussion

video upload by AJH Synth Official

"A minimal jam using 2 Chance Delay modules, triggered by a sequencer clock, with the Entropic Doom to create both percussive and melodic noise-based sounds. Also a simple dual-oscillator analogue bass line using 2 Vintage Transistor Core VCOs and the Transistor Ladder Filter. Turn on Subtitles/Captions for an explanation of what's going on.

The Chance Delay generates randomness with its 'Chance' control, which determines the probability of gates occurring. It also uses its Length control to divide the frequency of the incoming clock signal - this is done by forcing the gate lengths to exceed the interval between clock pulses, and not producing further gates until the current gate cycle has finished. It also has a gate-delay function, and all three of these features can be voltage-controlled.

The Entropic Doom is a noise generator with a built-in, voltage-controlled, low-pass filter. This VCF has 2, 3 and 4-pole modes, and is resonant, producing significant self-oscillation in 4-pole mode, whilst also tracking 1V/Oct. This means it can be used melodically, extending it's usefulness beyond just noise washes or percussion. Additionally, it includes an audio input to add other signals into the pre-filter feedback loop, and it can sync it's noise frequency to an external source. To top it off it also features a CMOS ring modulator and XOR VCA, both of which can be used with or without the rest of the module. This thing can go from subtle and pretty timbres to crushing, mangled, distorted chaos.

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.

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.

'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')."

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.

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.

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.

'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.

'Old School Jam' All-modular, Step Sequencer, Bucket Brigade Delay, Eurorack FX, and no quantiser!

video upload by AJH Synth Official

"Un-quantised, old-school sequencer fun: Inspired by early sequenced electronica such as Tangerine Dream and Klaus Schulze, much of whose music used a Moog 960 sequencer, which didn't have quantising features, and were sometimes difficult to tune accurately or reliably. Such as the track 'Phaedra' by Tangerine Dream, during which the Moog performing the opening pattern had to be re-tuned during the actual recording, and it was left on the album! Yet it sounds great, it's imperfect tuning adds so much to the atmosphere of the music, irrespective if it was deliberate or a 'happy accident'.

Here I use an un-quantised sequencer, in fact an Erica Synths Sequential Switch, with it's CV expander that turns it into a great little 8-step sequencer. I also run it through the AJH Synth CV Mix, to offset the CV going to the oscillator, allowing me to push the output into the negative CV range. I then send this shifted signal to the VCO's frequency modulation input instead of the 1V/Oct... just to make it more difficult to tune! Seriously though, this was a fun experiment, and taking off the digital stabilisers (or quantisers) once in a while is highly recommended, and a good learning experience. This was an all-modular session - no external FX or mixing, just Eurorack modules for all functions.

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.

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

Meet us and the modules in person this year at Superbooth 23, Berlin, on May 11th to 13th.

SAMPLE HOLD & SLEW User Guide: Multi-function Eurorack Modulation, Noise, Internal & External Clock

video upload by AJH Synth Official

"The SAMPLE HOLD & SLEW is a 12hp Eurorack modulation source, featuring both sample & hold, track & hold, a restrict function, internal noise source with colour control that can also be used as audio, internal clock that can be sent to other modules, and external clock control. It also has a well-featured Slew section, with selectable slew up and down only, gate control to switch it on and off, linear or exponential response, and this section can be used completely independently from the rest of the module.
This module can function extremely well independently, having it's own built-in clock and noise source to generate random voltages. However, it can also serve as a master clock for a generative patch, or triggering a sequencer. Alternatively, it can be slaved to a sequencer's clock, the gate output of any CV controller/keyboard, or other modules, so that it can generate random voltages in time with the music, even allowing the slew (or glide) to be added to individual steps in a sequence or pattern. This module is brilliant for making sequences more interesting.
As a simple noise source the bi-directional colour control applies low-pass or high-pass filtering. This is also useful when used with the sample/track & hold to determine the range of random frequencies or voltages that will be generated, as is the Clipped noise feature, which creates more significant differences between each sample, and the Restrict control that limits how far each new generated voltage can be from the last. When also used with the Slew and Exponential features it can then generate a smooth, ever-changing CV signal, which is ideal for use in drone sounds, modulating a VCF, VCO, VCA, an LFO, and any other modulation or audio.

'Filter on Filter' Jam: Ladder into Fixed Filter Bank 914 & Lunar Module 'Bit-crushing' Drum Sounds

video upload by AJH Synth Official

"Minimal Synth & Percussion Jam: 3 VCO's into Ladder Filter, then Fixed Filter Bank 914, with DH-ADSR envelope control over mix of both filters. Also down-sampling/bit-reduction effect using the Lunar Module to crunch then distort incoming audio/drum pattern from an iOS app (Patterning 1).

The classic Moog Modular-based Fixed Filter Bank 914 totally transforms the sonic character of the output from the Minimoog-based 24dB low pass VCF, creating a vocal/choir timbre, which is fed 3 sawtooth waves, each with their own LFO/modulation. The envelope automates the FFB module's built-in mixer, morphing the sound from just the Ladder VCF, to the Ladder through the Fixed Filter Bank. The Lunar Module is great for taking a too-hi-fi sound and giving it some lo-fi character, with optional crunchy distortion, making it sit more comfortably alongside it's analogue Eurorack neighbours. Old-school, vintage-voiced sounds and circuitry FTW.

'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.

'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.
Patch sheet PDF: https://kvisit.com/8AE/_v8G

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.

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.

'Next Phase Voices' - Vocal-like patch using a Phaser like a VCF (Eurorack Modular Patching Guide)

video upload by AJH Synth Official

"This week's 'Patch of The Week' uses the powerful NEXT PHASE Eurorack phaser module as though it was a VCF, with a step sequencer controlling it's frequency by CV - this allows suitable frequencies to be cherry-picked to suit each sound or event. Here the Next Phase is being fed 2 VCO's and some pink noise, which it is tone-shaping to create a human voice-like timbre. The 2 sawtooth waveforms are being pitch-modulated by separate sources to create some organic, human-like instability, and noise is added to give some 'breath' to the tone.

The Next Phase is a complex beast, whilst it can be used very simply and easily, even just to emulate the best phase pedal designs of the past, it can however go way beyond that. Extensive CV control of parameters, coupled with a total of 64 combinations of both 12 phaser 'Stages' and 12 'Emphasis stages', means that this is a very powerful tool for creating unusual or otherworldly textures and soundscapes. See our Next Phase User Guide video for examples."

The ADSR - Why do you need one? Understanding ADSR Envelopes, their behaviour and uses in Eurorack

video upload by AJH Synth Official

"There are many forms of envelope generator, and simpler forms of EG are popular nowadays, for convenience and space-saving, but is the good old Attack/Decay/Sustain/Release or ADSR envelope still worth having? All forms of EG have their pros and cons, so here we'll take a look at how the ADSR works, and some examples of why you might want at least one in your Eurorack case. The focus here is on usage with a keyboard, as this is where a full envelope really shines, since it can also do the same job as simpler forms, such as AD, AR, etc.
The DH-ADSR featured in this video is an expanded version of a single envelope from the Contour Generators module, and so it is also based on the classic all-analogue Minimoog EG section, and shares it's characteristic behaviour. It adds a separate control for Decay and Release, along with an inverted output, with two voltage ranges set by an internal jumper. It also has a 'Slow' mode, for very long envelope times, and a looping/repeating re-trigger function, meaning that it can be used as an LFO, with custom rise, hold, and fall times, or as a delayed envelope for use in conjunction with another EG in order to create complex, evolving envelopes.
