Polykit-16 with added performance modes
video upload by Craig Barnes
"When I first built this synth although it was bi-timbral I never really made the operation so you could easily use the bi-timbral modes, it had patch setups, but not performances to take advantage of the dual sounds, so this week I went out if my way to add the performance mode."

Some rambling on the polysynth #synth #analog #synthdiy
video upload by POLYKIT SYNTH
"Here is some rambling on the last build steps of the polysynth. It took me more than two years to come this far. I finished the input section and build the acrylic case out of parts that I ordered. It was the fist time I glued acrylic and I think it turned out great!
Sorry for the quiet voice in the demo part!

POLYKIT DIY synth voice is complete #eurorack #synthdiy #analog
video upload by POLYKIT SYNTH
"I now have all basic modules for a synth voice together. Find the Eurorack DIY kits in my store.
The modules are my Eurorack Core VCO, VCF, ADSR and VCA. In addition, there is an external LFO, reverb on the output and a sequencer.
Find the full DIY kits and PCBs here: https://store.polykit.rocks

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.

Stunning DIY VST Controllers by Craigyb
This one is in via Florian Anwander via the Sequencer.de forum.


"So when I was 16 (around 45 years ago) I used to dream of the Arp Quadra. A friend of mine who wasn't a keyboard player, but just wealthy bought one and it was sat in his front room doing nothing unless I could call around after school and have a play on this great synth.
Now I know I could probably afford to buy one, but the wife would kill me quicker than the Russians, so instead I took Cherry Audio's VST of the Quadra and created a physical beast with a PC built in to create sounds.
I then followed that up with a synth that I've never met in real life AFAIK but is also quite legendary, the Elka Synth (again a VST emulation by Cherry Audio).
I'm currently working on the Memory Moog version (MemoryMode by Cherry Audio) and I just need to finish the actual hardware as the software controller is complete."
Further below are a few more creations from Craigyb in a separate thread on the Sequencer.de forum here.
"This is a small collection of some of the real synths and accessories I have built over the last 4 years.

Polykit Building an Analog Polysynth - Controls Part2
video upload by Polykit
"In this video I look into building a control board for my DIY analog polyphonic synthesizer. The board has sixteen rotary encoders which can be freely assigned to any of the synthesizer's parameter. There is a 16x2 display for user feedback.

A SEQUENCER FROM BERLIN - THE MFB-601
video upload by Polykit Synth
"In this video I look into the history of MFB, a Berlin based manufacturer of musical instruments, and repairing a vintage jewel, the MFB-601 digital sequencer from 1983.
The MFB-601 is sequencing my Kosmo modular synthesizer. Two VCOs are going through a Steiner diode ladder VCF and a spring reverb tank. The MFB-601 is also triggering the MFB-501 drum machine to stay in sync.

The Polykit X1 DIY Semi-Modular Analog Synthesizer
video upload by Polykit
Follow-up to Prototype of a PATCHABLE analog SYNTHESIZER
"The Polykit X1 - a DIY semi-modular, analog synthesizer. It is based on the voice card I’ve build over the last months. It brings out all parameters of the card and offers a lot of variations through patching.
I've been so happy with the outcome of the voice card for a polyphonic synth that I've build an interface for a single card. It holds jacks for control voltages and signals, pots for all parameters, switches for filter responses, utility circuits and a power supply. It is the first time I used SMD components for all major parts.
You can find all needed files to build one yourself on my GitHub site https://github.com/polykit/polykit-x-...
