If one could isolate the reverb signal, one could possibly apply a
compresser or maybe a gate to crop the tops off the attack.
of course I'm not certain this would produce the effect desired.
Does the band filter (efb) work correctly?
Some of the other band filters produce squealing noises. You'd think that
would produce silence. They don't. I seem to misunderstand the cutoff
filters, because I seem to hear pitches in the red zone but distant--am I
hearing harmonics in the green zone?
