Prophet 12 Patches, based on the Prophet 5!

video upload by Erich Izdepski

"No talking! Put the vintage sound of a Prophet 5 in your Prophet 12! Buy now from

These Prophet 12 patches are based on the original presets of the Prophet 5, but with the Prophet 12 sliders programmed so each patch is really like several. With the extra controls you can alter the sound into something very different and impossible to do on the original Prophet 5. They take advantage of the Prophet 12's special features- effects, real-time slider controls, velocity, stereo output, and its powerful modulation matrix.

The Mighty ARP Axxe II

video upload by Erich Izdepski

"I performed major repairs on this synth as documented here. Everything works really well. This is a sales demo video but will also show you how cool this synth can be.

This is a great synth. Powerful filter with the ability to play it in tune with the other oscillators. Great spacey sound fx potential. Much stronger audio output level than the Behringer Odyssey (which I have and really like). Can control Eurorack gear or other analog synths using CV (has pitch, gate, and trigger in and out jacks)."

via this auction

"This is a great little synth with many interesting abilities. One of the best single oscillator synths, in my opinion, and I have owned several.

Here is a list of problems I fixed:

Several sliders did not affect the sound- all sliders cleaned, lubricated and working fine now

replaced all key bushings; cleaned key bus bar

repaired about 10 keys with 3-d printed parts

replaced power LED – new green LED with a 2.2KOhm series resistor installed to control voltage

installed a fuse and fuse holder in power supply

replaced IC 723, large filter capacitors, and tantalum capacitors in power supply

replaced tantalum capacitors at input to positive and negative rails on main PCB

not in tune – calibrated and sounds great

check power supply voltage output and look at ripple – calibrated and voltage is spot on and clean

You can search for my blog ( and read about the repair details.

Even has the original slider caps!"

Roland JX-8P with Kiwi Mod

video upload by Erich Izdepski

via this auction

"This is a great analog synth from the mid-1980's. This one has the Kiwi Mod installed which adds hundreds of sound slots, adds more modulation options, stores patches in static RAM (so no battery needed anymore), etc.

Includes the original Roland hard case.

The synth is in very good shape and everything works EXCEPT the arpeggiator and the sequencer features of the Kiwi Mod do not work. This could be fixable. I didn't do the mod and when I bought it things didn't work right. I found a short between two data lines caused by a tiny solder blob. Once I removed that, the synth played perfect except for the arp and sequencer. Maybe the installer made some other minor mistake affecting these other features. (This may have to do with the resistors that get altered when mod is installed. I just don't have time to look.)"

"Check out our Signal article on CV and Gate outputs -

Join our pal Wes for a look at those fun lil jacks that've been popping up all over hardware for the last decade or so!

CV and Gate functionality is nothing new, having its roots in some of the earliest synthesizers, modular and otherwise! In the modern day there are a ton of creative uses for CV and Gate when it comes to hardware, so lets explore a few and see where it takes us !"

Wing Drum and Gecho v2

video upload by Gecho Loopsynth

"This is the metallic timbre #11 from the Wing Drum, processed by Gecho Loopsynth, channel #33 Dekrispator. It is an example how to modulate the sound engine in Gecho by external sound, to get interesting textures. Similar effect can be achieved with microphones. Envelope, delay and filters in Dekrispator can be switched on and off separately, here everything is left on."

Gecho v2, synced start with Pocket Operator

"A quick guide how to set up these two devices to play together in sync (this feature appeared in the firmware version 1.0.118).

In the PO, enable SY1 mode (key+bpm), then start the playback. Gecho will listen to the click track and derive the tempo from it. Then stop the PO playback, select channel (don't press SET), and start the playback again.

You can also select the channel first, then start the PO - they will still be in sync however not necessarily matching at the start of the bar (which may give interesting results too)."

1976 Paia Model 4700 Analog Modular Synthesizer Deep Dive

video upload by Mears

"A deep dive on this rare, and synthesizer almost 50 years old. I've spent countless hours restoring it, and am very pleased with the results. It can produce a wide range of sounds, thick and beefy baselines, pillowy ambient textures, fat analog drums and so much more! This video covers the features of the synth, detailed shots and explanations of the restoration and internal components as well as a ton of high quality audio recordings of the various sounds this synth can produce.

Here's where you can find a whole bunch of great info about this synth:"

via this auction

"Really neat vintage synth, in great working condition. I restored it electronically 3 years ago, and have only used it in my home studio. I'm the second owner, and acquired it directly from the original owner whom purchased it in the 1970's, I believe it's from 1976. I have a bunch of paperwork for the synth somewhere, if I can find it(I'll try, it's buried in boxes somewhere!) I'll include it as well. It's worth noting that during the restoration, I preferred to keep the synth as original as possible, but electronically stable, and to make a 50 year old synth as reliable as possible. It includes and uses the original "pin" cables, so neat & rare. That being said, it's still a very old synth, from the early days of modular synths, when slight changes in mains voltage and temperature variations manifested themselves in "interesting" ways. I'd assume that the purchaser of this synth understands that and doesn't expect the oscillator tracking and tuning stability to be similar to modern synths. Please watch the Youtube video I created for this synth, which goes into great detail about the synths condition, and should answer any questions you have, and give you a clear idea of what to expect if purchasing.

One last thing, this will have to be sent in 2 boxes, and the synth is fairly heavy(each piece is 11kg on it's own). The shipping rate on the listing is not representative of what the actual shipping cost will be, so please if purchasing, expect that the shipping rate will be higher than indicated on the listing. The calculated shipping on Ebay doesn't accommodate multi-box shipments unfortunately. Feel free to contact me for a shipping quote, and if you purchase, please wait for me to provide you with a quote before sending payment. I'll do everything I can to keep the shipping cost as low as possible, but also make sure it arrives safely.

Performance // Granular [Tetra] Grid // Instruōctional Patching

video upload by Instruō

"This patch is broken down in depth in my next Instruōctional Patching video which will be live premiering on Sunday 20th February at 6PM GMT.

This is a performance recording of a patch I created while experimenting with The Tetragrid from Manifold Research Centre.
There are several patching techniques used that I have been experimenting with lately that lend themselves well to harmonic patching as well as much more experimental compositions.

Core Techniques:
• Chaotic cross modulation with magnets (Hail the donut)
• Complex circular FM tones from Cš-L
• Rhythmic gating over index ratios, wavefold depth and signal amplitudes
• Granular/reverberant spatialisation using arbhar
• TZFM as tone generator and processor simultaneously
• Harmonic chord voice using Harmonàig/Saïch

The composition is much more aggressive and textural than my usual. Too much caffeine perhaps… or not enough?
I built the patch to be very hands on and immediate for manipulating the voices. The Tetragrid allows for a wonderfully chaotic interaction between its 6 modulation sources. At times things can stabilise and produce musical ostinatos but simply touching the interface will quickly mix up the patterns.

The algorithms defining the cross modulation in both the instances of audio sources and control generators are circular in nature and with dynamic influence over their ratios. They produce very diverse ranges of complex tones and patterns that can naturally stabilise.

A full written breakdown of the patch and access to the patchnotes can be found on the Learning/Patching page on Instruō website:

"I made this ambient tune with the idea to establish a dialogue between the Black Corporation Deckard's Voice, 4MS Ensemble Oscillator and the Qu-Bit Surface.

Deckard's Voice and the Surface are sequenced and triggered by Pam's New Workout (that also shares the clock to the entire system), while the Ensemble is sequenced by Hermod.
Divkid Ochd modulate various parameters of the Ensemble, QPAS, Mimeophon and Surface.

Effects Chains:
Deckard's Voice - Mimeophon
Ensemble OSC - QPAS - Z5000
Surface - Disting EX (granulator) - Mimeophon

Plus other few modulations from Pam's and Xaoc Zadar (with the D Channel in cycle) Hope you like :)"
