Just about to solder the last two switches on my sidekick and was wondering how you tune the filters? I remember following the guide for the Shruthi-1 control board, there isn’t one for the sidekick, does it matter?
You can connect the board to a Shruthi-1 digital board and follow the procedure.
- Don’t bother with the lowww and V/Oct settings (they are important only for having the cutoff frequency track the oscillators’ pitch).
- adjust “Reso” so that you get something pleasant when resonance is set to the maximum.
- adjust “DC” so as to minimize the clicks when you trigger the VCA (no signal coming into the filter board).
