[sdiy] Midi2CV accuracy(was MIDI2CV alternatives)

[Maarten Halmans]

Hi all,
the accuracy and midi2converter stuff is keeping me busy for some time
now.....What is from a musical point of view an acceptable accuracy when
working with polyphonic midi2cv converters? Very small differences in pitch
between two sources are audible, a difference 0.5 Hz at 440Hz is audible
right? So the desired accuracy is even better than 0.1% or am I missing
something?
Thanks,
Maarten
