Somebody should start an Analogue Systems list. I feel sorta
lousy leaving these messages here.

But...possibly some of you also have their multimode filter, so
take this tidbit I stumbled on the other day as useful info:

When using your filter as a sine oscillator, connecting a voltage
pot (like from a Doepfer A-176) to the RES IN jack will create a
fine tune control. Try it, it works swell!

It will also work for making fine adjustments when the filter is not
oscillating.

There you go...your off-topic tip for the day.
