Hack the 4TOMS
video upload by LARIX ELEKTRO
"The Larix-Elektro can be easly modified, yes !
The main components are through-holes. It means that you can change them easly !
here how to do it and some sound results.
So, with all the CV inputs, the jumpers, and the through-holes components, the 4TOMS is more than a basic four percussion generator."

We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.
NB! All kits in these series are simple and come with extensive user manuals which can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar."

Glasgow Synth Guild Oct Tone Sequencer Review
video upload by Molten Music Technology
"Oct Tone is 8 steps of Eurorack cyclic sequencing. Who would ever need more? It's a delightfully musical module with a great front end, some snazzy features and can cook up a storm in more ways than you'd think.
GSG did not send me the module; I bought it myself, and they have no idea I'm making a video review.

Modded Roland CR-78 - Individual Outputs!
video upload by foleytronics fx repair
"This is a CR-78 we modified to have individual 1/4” TS outputs for each drum sound. It wasn’t as simple as finding where the bass drum is generated and connecting it to a jack because we found the tone of the instrument would change without any buffering. Our solution was to create a buffer board that would isolate and amplify each of the sounds without sacrificing tone.
It’s really fun to use with a mixer - changing levels on the fly, reverb throws, different panning, you name it!

Drone FM resonant filtered noise
video upload by Ghost In Translation
"This is Drone 2.0, 4 voices with individual 1v/oct pitch control, each voice has a sine oscillator and a resonant filtered white noise that can be mixed together and controlled by CV, the mix of the 4 voices can also be controlled by CV. Finally it is also possible to control the FM range of the 1v/oct inputs via CV, allowing nice FM at audio rates in place of 1v/oct sequences.

PolyKit DUO 6 Voice DIY Poly Synth by Craig Barnes
video uploads by Craig Barnes
"PolyKit DUO first tests as a 6 voice poly. some bugs to iron ouThis is the first test of the basic functions of this 16 voice DCO based analogue synthesizer. It will be bi-timbral when complete with upper and lower sounds with 8 voices in each, dual, split and single modes. Still a lot more work to be done. t in the software around the portamento controls, but other than that it's almost there.
https://github.com/craigyjp/PolyKit-D..."
Playlist:
PolyKit DUO first tests as a 6 voice poly
Bi-timbral PolyKit 16 updates
Second phase of the PolyKit construction was to create the bi-timbral software so it can create, save and load two sounds at once. so far so good with some spurious aftertouch in there.
PolyKit 16 first fully polyphonic test
PolyKit DUO preliminary demo with only one filter installed.
Preliminary testing of a single voice as I have no more AS3372E chips and they seem to be lost in the mail from Portugal. Had a few issues with wiring, always the way when you do two voices on a board at once. Filter 1 & 2 EG outputs were swapped. And EG level for voice 2 had two pins swapped on the 4053 switch between velocity and full level. Need to debug some more but so far I'm happy.
PolyKit 16, a bi-timbral 16 voice dual DCO Polysynth.
This is a short demo of a small selection of sounds produced by the PolyKit 16 programmable Polysynth. It is based on the PolyKit DCO by Jan Knipper and has been expanded from 6 note polyphonic to 16 with dual DCOs instead of single, additional sub and triangle outputs and dual LFOs and a noise source per bank of 8 voices. Still more work to do on the programming like trying to create patches as well as presets.
Poly6 Teensy 3.6 based Polysynth with patch memory
video upload by Craig Barnes
"Teensy-Poly6
This is a polyphonic synth forked from albnys/TeensyPoly6 converted into a 2U 19" rack.
https://github.com/craigyjp/TeensyPoly6
The analogue interface now uses 6 MUX chips to read the pots and switches so there is no need to connect top the top or underneath of the Teensy 3.6 for the extra analogue inputs required. It runs smoother now as well.
The schematics are upto date now with the latest mux changes.
The synth is built using a teensy 3.6 overclocked to 192Mhz and is programmed in Arduino IDE using the teensy audio library.
Easily upgrade to a T4.1 or even a T4.0 as very few connections are required now. Increase of polyphony is probably available with a T4.x.
How it sounds in the original keyboard form, this sound engine is unchanged.

Sequential Prophet 600 clone on proto board with Gligli upgrade
video upload by Craig Barnes
"A complete clone of a Sequential Prophet 600 built into a CME UF60 case, push buttons were used instead of the membrane. AS3372E chips were used instead of the standard AS3372 which are expensive and hard to find. Total cost around 600 euros and a month to build on and off."
Moog Source based clone controlled by Teensy 3.6
video upload by Craig Barnes
"I love the Moog Source but really cannot justify over £2000 to buy one without MIDI etc. So I made a monosynth based on the style of the Source, I replaced all the button/value selections with actual pots to make editing simpler. I added another LFO to control the PW of each oscillator with depth controls. The ladder filter is from the MemoryMoog. It stores 999 patches and has MIDI and CV inputs. Note priorities etc. The envelopes are Electric Druid EnvGen8C devices so I have added log/lin envelopes and looping modes."
More Moog Source clone sounds
video upload by Craig Barnes
"This is my attempt at cloning the classic Moog Source but also bringing it upto date. I built this synth over a year ago before the war started. I recently took it off the shelf and tried to remember how exactly I wired it up as I made very few notes of the schematics, most of it was on the fly or from tried and tested methods I had in my head. But I think I got about 95% of it loaded into GitHub now and I made a few changes along the way. I updated the software and added more features over MIDI such as aftertouch, midi clock sync etc. it sounds better in the flesh than recorded on my phone but currently my studio is out of action due to Putin's ongoing effort to destroy this country. I hope you like it and the other synths on my channel, I'm not much of a player so relying on the arp from a keystep whilst filming with my phone. The last sound "Thump Bass" is an example of the repeating envelopes for the filter and amp.

VCDO based Polysynth in a Crumar Stratus case
video upload by Craig Barnes
"A 6 note polysynth design that I have been building on and off for about 3 years since i had the idea. I gutted an old Stratus as I got it very cheap and the original idea was to only replace the organ generation circuits with real VCO's or DCO's to feed the Stratus CEM filters etc. But as it developed I ended up replacing more and more of the Stratus with my own designs or interpretations of designs I've found on the web. It switched between CEM3340 VCO's an Electric Druid VCDO1 chips, eventually settling on the VCDO1 chips even though the waves are only 8 bit, its very PPGish.
The specs are as follows.
Dual Electric Druid VCDO1 oscillators with modified firmware for new waveforms and performance.
Multipole filters similar to the Shruthi design but using the CEM3320 and pole mixing. 16 states, resonance, key tracking, EG depth & invert and looping.
LFO with 16 waveforms, slope and delay, depth and multiple destinations. Electric Druid TAPLFO3.
White Noise source based on the Electric Druid Noise 2
3x EG's per voice, Pitch, Filter and Amplifier, switchable velocity on each EG, Electric Druid EnvGEN8c.
Bit Crush on the waveforms
Poly/Unison modes
999 memory locations
MIDI and CV in/outs and can be used to drive CV based equipment"
Korg DW6000 editor built into the DW6000
video upload by Craig Barnes
"This is a Teensy 4.1 based sysex editor for the Korg DW6000, it can hold 999 patches and update the DW on each patch selection. Sysex params also have corresponding CC numbers so it is easily controlled by a DAW or other external controller. It can also receive and send MIDI over USB to all connection to a PC or MAC without a MIDI interface.
It can receive sysex patches over MIDI and these can be saved in the editor or synth.
In master mode the editor is in charge and simply sends new patch data every time a program change is made. The synth memories are irrelevant at this point, but it also allows you to build a bank of sounds in the synth if you wish as any of the patch data sent from the editor can be saved in a synth memory location.
in slave mode the editor simply sends a program change to the synth and recalls a patch. You can edit the patch with the editor and save it in the synth, but it will not be in sync with the editor memories 1-64.
You can send individual or all the patches of the synth out as sysex messages from the menu.
Any suggestions I will consider implementing if possible.
Also a copy of the factory patches are stored onboard and you can send these at anytime to the DW6000 to factory initialise its sounds.
Also you can send all of your patches from the DW6000 to the editor to bring it up to sync with your synth, probably the best thing to do. The only caveat is you will have no patch names as the DW6000 does not hold that data, so you will have to rename the patches if you require names.
Schematics and code can be found here.
