hello cuari,

as far as i know it is possible to convert audio into
squarewaves, but i can't tell about the maximum
frequency possible. i doubt that it will work within
the full frequency range of an a111 for example.
anyway, i haven't tried that yet.

pulsewidth modulation should be possible when using a control
voltage at one of the inputs, depending on the symmetry
of the audio waves. haven't tried that too.

hmmm looks like i have to do some tests during next week.
this weekend i'm going to rotterdam, doing a jam session
with friends of mine (i'm not using my modular on this),
so i can't try it earlier.

best wishes

ingo
