hello dave,

this is normal with the a102, don't worry.
the a102 begins to oscillate pretty early.
in this filter nearly all parameters interact
with each other and the extra-big resonance
knob range just makes sure that you can
reach all the sound colors possible with this
filter design.

best wishes

ingo
