"This synth is for sale. You can buy it directly (sales.ohmstudiohm@gmx.fr) for 1450 euros or buy it on eBay (https://www.ebay.com/itm/305202255093) or Reverb https://reverb.com/item/74807341) [pics captured here]



This is demo mainly to show how easy it is to program this synth thanks to the amazing work Bob Grieb (Tauntek) did by rewritting the firmware and enabling Midi Control Changes messages on this synth.

The only drawback (due to the hardware) is you have to retrigger a note for every change you make on a parameter, except for a few ones that a real time (resonance, DCO and LFO waveshape for instance). Just a minor annoyance compare to the original programming method (which is actually not the worse of that kind).

The BIT99 and BIT01 are very nice sounding and quite comprehensive 6 voice analog synth. They feature 2 DCOs with triangle, sawtooth and pulse waveform, in octave from 32 to 4 and you can combine the 3 waveforms on each oscillator. Dedicate ADSR enveloppes for filter and amp with velocity control, 2 LFOs, noise generator, split or stack possibilities etc

IMO they only lack a mixer for the 2 oscillators, LFO PWM (though you can control the PW with velocity) and a hi pass filter.

But the sound is very nice, I favore it over the Oberheim Matrix 6 for instance. It sits very easily in the mix. Build quality and keyboard are also of upper level."
