speaking of res loops (rs120)..
 i was playing around w the res loop on an AS rs110 last night
 when suddenly a patch i made caused the audio to go away and
 not come back by undoing the patch. i patched an a140 output to
 the resonance loop's input (nothing connected to res loop's
 output.) and 'blip', out goes the signal. i thought i had a bad
 cable or jack, traced the signal problem to the filter, it had
 stopped passing audio, was 'locked up'. that is, until i wiggled
 the freq knob on the rs110, then the sound came back w a
 screech. i assume the filter went into self-oscillation at an
 inaudible freq when i plugged in the a140. anybody know if is
 this harmful either way, anybody know more about possibly
 harmful patches
 i'm generally a plug-anything-to-anything experimentor but this
 has me wondering if it's possible to abuse a circuit to death.
