the a123 is a fully resonant highpass filter and it has
a very stable self oscillation over the whole frequency band.
i know that some people don't like the a123, because the
resonance poti is scaled in an uncommon way, but i personally
love it. i'd say it is a real highpass filter, so what do you
mean with "somehow strange"

yes, absolutely, especially when everything is triggered by
the same signal.

same with me, it is a very handy module.
