i tried the following from the wiki:
1:1 Filter tracking would be a simple matter. Just connect CV out into a 100k resisitor, and then into q10, like the CV for cutoff mod above. You will probably want to wire in a switch between there.
i took the CV at J6 if i recall well. the result was just that hi pitch notes only would be heard, and loudly (as the cutoff would be very open). maybe i did the mod wrong, but if not it was not really to my taste.
anybody got experience to share there?
also, from the wiki, the following would be great:
For DevilFish like filter tracking, this is a little more complex, as we need to scale the voltages. This would probably mean using a pot as part of a voltage divider, and possibly multiplying the CV in before going through the divider.
how could i do that ? anybody with some rough ideas i could experiment with ?
