[sdiy] scales for a pitch voltage quantizer

[harry bissell]

Hi Wilfried:

No... actually the octaves are continuous... so in one
case the high octaves are minor, in the other case the
low octaves are minor.

Your project sounds real interesting. Let us know how
it works out (and how we can build one too !)
