I’m sure the 940 resonance wasdesigned to be similar to the 904a, but I don’t mind changing theresponse to something more useful. I tested this with a 100K pot and thought a 75K value gave the bestrange, but I don’t have that value in my resistor stock and didn’twant to muck up the board with parallel resistors. There is some difference at maximumresonance when you change R29. Thesine wave is not as “pure” at rez=10,instead it seems to be more “modulated” by the input waves. But I tend to stay at low to mediumresonance, so it didn’t matter to me.

I agree... This filter sounds AMAZING. :) Ithink I might do the resonance range mod too. For my use, I don't think there'senough of a sonic change past the halfway point in the res pot to warrantkeeping it this way.
I can see myself ordering one or two more of thesefilters in the near future.
