MiniMod Keyz & Arps - Keyboard Split function and Dual Arpeggiator running 2 synth voices

video upload by AJH Synth Official

"Full-length 'landscape view' video on Sunday. Using the keyboard split function of the Nifty Keyz with an arpeggiator on both keyboard zones. This is then controlling both the on-board MiniMod voice and a separate Eurorack case, containing another 3-VCO voice and the Gemini 2412 Dual State-variable VCF. These 2 SEM-style filters are processing the same sound very differently, and are modulated the Dual RVG random voltage event generator, and the Multi Burst Envelopes. The MiniMod Keyz voice uses the Ring SM as a mixer and sub-bass/sub-octave generator, along with the classic Minimoog-based Transistor Ladder Filter.

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

video upload by AJH Synth Official

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

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

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

video upload by AJH Synth Official

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

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

"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."

Gain Switch Multi: User Guide - Easy Access to Overdrive on AJH Ladder Filter & Cascaded VCA

video upload by AJH Synth Official

"Here's how to use the Gain Switch Multi module with the Transistor Ladder Filter, Discrete Cascaded VCA, and Gemini 2412 VCF. With the Ladder Filter and VCA it allows convenient access to the gain jumpers on the back of the module, so that you can simply turn on and off the increased gain level feature, and add musical overdrive to your sound - this simulates the old Minimoog trick of connecting the headphone out put to the audio input to add some desirable distortion to leads etc. With the Gemini, the module will connect to it's two jumpers which determine the resonance available on each of it's two filters - the normal SEM-style level of resonance, or a much higher level, allowing either or both of the filters to self-oscillate.

Also there's a passive 6-way multiple to further make use of it's tiny 2hp Eurorack footprint.
