"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.

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.
