[sdiy] Midi octave shift

[rsdio at audiobanshee.com]

One thing to consider is that even the analog control might want to be quantized, at least for Coarse.

For example, the coarse VCO knob on the SCI Pro-One is rotary switch for Octave 0 through 3. The Frequency (fine) knob spans about 1.5 octaves, I think, to make it possible to reach every note. Of course, rotary switches can be harder to find and more expensive than pots, but if you settle on stepped Coarse and continuous Fine then you can use the same controls for both CV and MIDI.

In other words, I agree that it’s a tough sell to add dedicated controls for MIDI. But it actually seems like more of a feature than a sacrifice to design the analog and digital controls so they both have the same paradigm.
