I made some adjustments to Biminiroad’s Drift VCO with a reset as described in the Richard D. James interview: the oscillator is set back to its starting point when tones are no longer being generated. For frequencies above 1000Hz the LFO is reset, and for frequencies below that point the feedback loop is interrupted and fades back in when tones are generated again.
The drift cycle is around 50 seconds and it’s fun to hold a perfect fifth (e.g with middle C as the upper note) and listen to the beating increase and eventually reach a perfectly tuned interval before slowly starting to beat again. Due to the feedback loop the drift amount is slightly different for frequencies below 1000 Hz (see the explanation in a previous post) whereas the LFO rate is constant for the frequencies above that point. That means that at least for frequencies below the switching point one has the possibility of a slightly different drift for each note, without running into the complexities of post-quantizer bending.
