[sdiy] various scales for a Midi-to-CV ??

[Florian E. Teply]

hiya Synth folks,

I'm currently thinking about some sort of converter from MIDI data to
Control Voltages. What i'd really love to achieve is the possibility to
have this converter to respond to a selection of different scales. For
that matter, there are a couple of scales around for any given base
tone. So in a clean tune (as opposed to a well-tempered tune) an A flat
is a tad different from an G sharp frequency-wise.
What i'd like to know is whether or not this is even worth the hassle of
computing all those frequencies with those VCO circuits around.
The background on my thinking is as follows: I'd like to be able to play
a couple of different scales with my synth. Not necessarily all possible
  scales, but at least some sort of selection among all the scales
around like, say, Dur and Moll scales as well as some arabian scales,
all, those tuned to clean base notes like G sharp or B Flat or something
like that.

What do you guys think about that??

Greetings,
Florian
