'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.

MiniMod & Ribbon Controller - AJH Synth Eurorack Ambient with Gemini 2412 'SEM' style Dual Filter

video upload by AJH Synth Official

"A 2-voice ambient performance using the Doepfer ribbon controller with the AJH Synth MiniMod eurorack modular system, here incorporating the Gemini 2412 'SEM-based' dual multimode filter/VCF. Simple 2 note/2 VCO chords are shifted in pitch with the Ribbon, and pressure sensitivity used to control the Gemini's overall frequency, and the level of pitch vibrato from the Dual LFO module, which has a built-in VCA. A third VCO via the Transistor Ladder Filter creates a single oscillator drone sound (a square wave with pulse width modulation/PWM), whilst the Dual LFO also modulates the frequency of this VCF, and both VCF's on the Gemini in position to each other. The Gemini is used as a stereo filter, with both going of it's VCF's going to separate VCA's and audio channels to creates a stereo panning effect.
The Gemini can be used as 2 filters in series, or in stereo with a single audio input signal, but here both filters are processing a different VCO via their individual inputs, whilst the global Dual Frequency CV function of the module's central mix bus section allows them both to be controlled in unison, in addition to, or instead of their own individual CV control. This offers a huge amount of flexibility.
A suitably large reverb is added in post to add a film/movie soundtrack quality to the sound.

MiniMod 6U Full System 'Berlin School' style performance - Melodic Eurorack Modular - AJH Synth

video upload by AJH Synth Official

"2-Voice 'Berlin school'-style performance, and first of a few videos featuring the same module lineup from the new MiniMod 6U Full System, now available to purchase from https://ajhsynth.com/Minimod.html, pre-installed in a powered case. This is an 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, and a single VCO with 2 sub oscillators lead synth. It uses all the modules from the Minimoog-based part of the system, along with the Gemini 2412 SEM-based dual VCF, and the indispensable Ring SM mixer, sub-bass generator and ring modulator.

Reach the LOWEST Notes with your Controller - PRECISION VOLTAGES to Transpose CV Signals

video upload by AJH Synth Official

"Ever been frustrated that your CV controller keyboard, sequencer or MIDI to CV converter doesn't reach the lowest notes that your VCO or other oscillators can produce? The PRECISION VOLTAGES module by AJH SYNTH can fix this problem. Using it to shift the CV output of your device up or down by up to 10 octaves (and 12 semitones) means that you can reach a huge range of the pitches that your synth can produce, even into the LFO range. Many controllers won't output negative CV signals, meaning they'll only go so low and then stop producing more notes, so you may find yourself pressing the lowest keys but still only getting the same pitch. This isn't a fault with the controller, but a considered compromise, depending on the design and intended functionality of the device. However, when paired with the Precision Voltages this is no longer an issue.

In the future a full 'User Guide' video for the Precision Voltages will demonstrate the many uses and functions this extremely flexible module can provide.

This video also relates to the earlier video demonstrating how to use the GLIDE + NOISE MkII module to access and use the CV BUS for controlling multiple VCOs from a single patch cable: [below]

How To Use the CV BUS - with the GLIDE + NOISE MkII Module or Mini Mod Eurorack Modular System


"This video shows you how you can use the CV BUS with a CV Controller (in this case an Arturia Keystep) via the Glide + Noise module (MkII version only) to control the pitch of multiple VCOs, and send the signal on to a filter or any other destination, thus making patching simpler, faster and tidier. There is also a section detailing the basics of what you'll need to know about bus boards to ensure that you can use both the CV BUS and GATE BUS, however a detailed video regarding using both will be coming soon.

Also, it briefly mentions how the PRECISION VOLTAGES module can compliment this system, and help you to expand the CV range of your controller, in case you are having trouble reaching the lowest notes your synth can produce. The AJH SYNTH MINI MOD system is based on the original Moog Minimoog Model D, but greatly expanded into Eurorack Modular format. Its high-end design and manufacture provides authentic vintage tones, with modern usage sensibilities, featuring substantial controls and socket layouts to provide a modular synth that is a true instrument to be played.

The GLIDE + NOISE MkII module can be used with any Eurorack modular system where access to the CV BUS is needed, along with a classic Glide function, and 3 simultaneously available noise outputs - white, pink, and red. Note that the original Glide + Noise MkI version of the module, since discontinued, does not have this facility.

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: 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.

Melodic Randomness: Chance Delay & Dual RVG (Eurorack Probability & Random CV for Generative Patches)

video upload by AJH Synth Official

"Visit AJH Synth @MachinaBristronica (UK) Saturday 30th. Experimentation with using 2 random event & voltage generator modules within a melodic, sequencer-controlled, modular synth performance. Randomness/probability/chance can form the backbone of a generative music patch, but also in more manually controlled situations, and are a great companion for step sequencers.

Here a purely analogue step sequencer is used, with the time variation function of the Dual RVG serving as the master clock, and the Chance Delay adding probability to each step occurring. In the previous video the Chance Delay was randomly passing the gate signals from a sequencer to the synth voice it was controlling, so some steps would be missing. This time the module is placed before the sequencer, so that all steps will occur, in the correct order, but randomly. Since the gates it is receiving is from the master clock, all of the sequencer steps will remain in time with the music.

The Dual RVG also simultaneously produces 2 random control voltages for each clock pulse, and so I'm using one of these to modulate the frequency of the Entropic Doom, which I'm using to generate a simple percussive sound. The new Triple Cross module is also featured here, and cross-fades between 4 pitched drones, forming a melodic chord, but with 2 separate LFOs controlling the cross-fading, so that the mix between the 4 notes/sounds is constantly changing.

2 of the VCOs from the drone sound are passing through the Wave Swarm, creating a buzz of additional sawtooths to thicken their sound. These 2 are heard through the Fixed Filter Bank 914 later on, which creates a more choir-like timbre to accompany the output of the Triple Cross. The Sonic XV is used as both a filter and a wave-folder for much of the melodic sequence, where it is at times accompanied or replaced by the same VCO passing through the Ring SM and then Transistor Ladder Filter into Low Fat VCF.

Expanding the Mother 32 Part 2 - More VCO's & Chords, Vocal sounds, External Filter/VCF (Eurorack)

video upload by AJH Synth Official

"The last of 2 videos showing some ways to add more flexibility and sonic power to the Moog Mother 32 using AJH SYNTH modules. The synth is semi-modular and designed with Eurorack compatibility in mind, so this unlocks the huge range of modules in the Eurorack modular ecosystem. Since the Mother 32 has that trademark Moog sound, the AJH Synth MiniMod range sit particularly well with it's vintage analogue synth lineage. The individual elements of the standard MiniMod voice are in fact based directly on the original R.A.Moog version of the Minimoog.

This video shows another example of adding multiple external VCO's to create a big, dense tone with multiple octaves, and also with 2 of the oscillators offset at different pitch intervals to create chords, just as was possible on the original Minimoog synthesizer.

Also shown is an example of using an external filter, in this case the powerful GEMINI 2412 dual multi-mode VCF, which is simply a case of running internal and/or external oscillators and sound sources into the filter, then back into the Ext Audio input, setting the Mother 32's internal ladder filter to maximum frequency (fully open), and reducing resonance to zero. Of course there's no reason why this filter cannot also be used as part of a patch, although the Gemini's two filters can also be run into each other internally (Cascade = in series) in the same way. Finally an example of vocal timbres/formant sounds, which can be achieved by many methods, but here using the wave folder featured on the SONIC XV diode ladder filter, and the FIXED FILTER BANK 914, which really is a go-to tool for tone shaping, allowing the output of 14 individual filters (1 low pass, 12 band pass, 1 high pass), each fixed at a specific frequency, to be mixed together at individual levels in order to dial in a desired tone.

Expanding the MiniMod Part 1 - Adding a 2nd Voice in just 2 or 3 modules (AJH Synth Eurorack tips)

video upload by AJH Synth Official

"If you have an AJH Synth MiniMod Eurorack system you might be wondering which modules to add next. We often get asked for advice about this, and of course It depends on what you wish to achieve musically, but we'll be uploading some video suggestions, starting by adding a second voice with just 2 or 3 modules.
Creating a second voice means having a second monosynth, so that your modular synth can then function as two substantial, separate analogue synths in one case. As the MiniMod comprises 3 VCO's as standard, adding an addition filter and VCA already makes this possible, but then adding the RING SM provides the potential for two, very big-sounding classic synthesiser sounds in one place, with one power supply, and minimal space. At the same time, as you're adding different modules to those you already have, it also hugely expands your sonic possibilities when using the system as a single synth, with vintage ring modulator, wave folder (Sonic XV), also Minimoog-style overdrive and switching mixer to mute or enable signals."

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.

'Für Klaus' - Tribute to Klaus Schulze, a Eurorack Modular Performance #eurorack #synth #ajhsynth

video upload by AJH Synth Official

"On this channel Sunday 8th @7pm GMT - a 13-minute track recorded as a single-take performance, and a purpose-made tribute/dedication to the late Klaus Schulze. The piece is inspired by his music directly, creating some sounds akin to those he used in the late 1970's, even including one of his sequences. Much of it was composed and rehearsed, whilst some of it was improvised, but I suspect much less so than Schulze's works, which were often much longer, involving more improvisation and more instruments. This piece consists of just three voices across 4 audio tracks/channels, altered or converted in real-time during the performance to achieve different sounds.

As a creator of electronic music, Schulze was one of the most significant influences for me (the video creator). His music, his attitude towards it in the interviews I read of his, and the way he worked alone to create dense, fascinating, complete musical performances and soundscapes, at a time when the technology was in it's infancy, and before later technologies such as complex computer sequencing, sound creation, processing and mixing were available. As a solitary musician, his was a great, empowering example. His bravery to improvise, experiment, and co-exist with imperfections, embracing them rather than fearing them, makes me warm to the artist and the music even more. Schulze used, among others, an early Minimoog (leads) and a large Moog modular system, which he customised with additional modules over the following years. Since the core AJH MiniMod system is directly based on the early, more desirable R.A.Moog version of the Minimoog, yet is entirely modular, it makes a great choice for this homage to one of electronic music's greatest pioneers.

'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.

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."

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.

'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.
Patch sheet with notes below.

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.

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.

Velocity & Aftertouch - How to control VCA/LFO/VCF with the MiniMod Eurorack Modular Synth

video upload by AJH Synth Official

"Some ideas and basic procedure for using keyboard velocity and aftertouch with the AJH Synth modular system. This can add a lot of expressiveness to your patches, all that's required is a keyboard controller that outputs these functions, whether it be a CV-equipped controller, or a MIDI/USB controller connected via a Midi to CV converter.

This video shows velocity being used to control VCA volume, aftertouch controlling LFO/vibrato amount, and both controlling filter frequency, but since this is modular these control signals can be used to manipulate pretty much anything that has a CV input. In some cases using it with the CV Mix will be particularly helpful to adjust the range of the controller's output to suit the intended target, allowing the CV to be simultaneously amplified, offset, inverted, and/or combined with other CV's.

I'm using an Arturia Keystep, which has a 'Mod' CV output - this can be configured in software to output either velocity, aftertouch, or the position of the 'mod wheel' touch strip.

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 Synth Low Pass Filters Compared: 3 Eurorack VCF's - Sequences & Sweeps (dry audio/no talking)

AJH New Module & Melodic Performance: Chance Delay, Wave Swarm, Gemini 2412, Fixed Filter Bank 914

video upload by AJH Synth Official

"A melodic track performed using a sequencer with the new Chance Delay module during the opening section. It also uses the Wave Swarm, Gemini 2412 and Fixed Filter Bank 914 together to creating backing chords/drone. The melodic sequence sound is just a single VCO going into the Ring SM, which adds a -1 and +1 sub/octave generated from the incoming VCO, and some white noise via its mixer.

Reverb and dual delay is added in a DAW.
