hello ingo (the not self-oscillating :-)),

afaik the a133 is not really a ring modulator, but like a vca,
it can be used to achieve similar effects.
i'll record a sample using the a133, but i cannot
do this before weekend i guess. i still have some troubles
with my recording card. one time it works, the next time it
doesn't. computers can be a pain in the ....

best wishes

ingo
