[sdiy] Frequency to MIDI Conversion

[harrybissell]

I agree with the posts of "it can't be done polyphonically"...

With a mono signal... you can convert to CV or to Midi.  I'm doing
this with the PV-1 board (also mentioned) with the CV digitized...and
fed to a lovely little MIDI board (PIC micro) made by Roman Sowa
(also of s-diy) which takes a seven bit input and streams MIDI messages.

I'm quantizing a theremin with it. Theremin is VERY monophonic.

Both myself and Mike Irwin (co-incidentally...also of s-diy) have used
a mono synth output to drive the P/V converter.  If you have any CV output
its better to process that directly. The Juno won't have that...
