from Onchip ... don't do it ... there are allready enough CEM synths
micon chip dist.

there are enough schematics around, the problem is that most
sound the same....
> 4) Are most people using 1/4" jacks for audio & control, or bannana

don't use banana jacks ... use standard walkman headphone jacks.
> 5) Any benefit of shielding cv cables? Can audio patch cables be
shielding is allways better than unshielding ....
> 6) When using 1/4" jacks for cv, don't you short the cv to ground at

you don't have to worry about that...
> 7) I've seen several CV levels used 0-5,-5-+5,0-10, etc. What's

0-5 is the cv pitch range...
-5 and +5 might be a signal (output of oscillator) like a sine
which has a positive and negative part
0-10 is a gate/trigger
> 8) What do the modular moogs use for jacks, cv levels?
> 9) Are schematics (books, mags) available for the Formant system?
Elektor published the complete formant, but you'll have to do some
searching to find the mags ...

fatar sells keyboards .... or you could ask Roland Benelux ...
> 100) Is this enough questions?
