Dave Smith Instruments SYNTHESIZERS

Sorry if I wasn't clear.  I certainly didn't mean to equate "Filter 
Cutoff Frequency" with "Amplitude".  They're obviously not the same 
thing.  I only meant to make the point that (for most synths that DO 
include a "VCA Level" setting) you CAN have the VCA Level turned up, 
and yet not hear a sound without hitting a key, because the Filter 
Cutoff is set to zero.  Fair?  :)

I actually tend to program a lot of patches that way on my various 
synths - with the VCA Level turned up, and the Filter Cutoff at zero, 
leaving the Filter Cutoff Envelope solely responsible for letting any 
sound through.
