Re: RE: DOMOAS - RESET and synchronicity

I fully agree with both of Dave s points below. I can imagine a homebrew sequencer that resets to stage 1 so that the next clock pulse (and gate signal for the

There are 2 ways for a reset function to operate - synchronously or asynchronously. Those are just fancy schmantzy terms for saying it either jumps to step 1

The 320 LFO has VC waveshape already, as Paul mentioned. It will also work well as an audio VCO, as long as you are not trying to track musical pitches
