Just a software update Idea. I know its possible to do this with the high and low pass filter.. But a bandpass filter would be great too. One knob to tune up and down the frequency.. and one knob to make the band wide or more narrow.
+1 for a third BP filter.
even better if we could change the HP/LP signal flow.
instead of just serial LP->HP it would be very powerful to be able to a) change the order to HP->LP and b) process in parrallel mode.
