Back in 2013 when I was making the first rev. of crOwBX I had this idea to do a "per voice" autotune system where a local microcontroller to the voice board would be able to set reference CVs at each half-octave of each VCO's frequency range. The "correction offsets" calculated by the program would then be used to add or subreact a small amount of CV on the autotune CV lines for each VCO. The small MSOP10 part (U2) in the corner of the crOwBX image (blue board) is a 4-channel 16-bit DAC, 2 channels per VCO for ranging and fine tuning. The working boards are in my assembled crOwBX cabinet, I should toss up an audio demo one of these days. The board pictured was my Guinea pig for evil experiments.
Similarly, as my VCO153 ultimately was to have a trasnposition selector as per the actual CS-80, I decided why not autotune the CSVCO as well. (There is also a simple MIDI provided.) These boards are the result. I never got out of the prototype stage with these but eventually...eventually.
