Maybe, but you have to weight that against the supprise the user feels
when the chorus comes in, all the channels light up, and thier DAW
suddenly tells them it doesn't have enough cycles anymore. Not to mention
the memory bandwidth hit from suddenly warming up all those buffers and
process() functions.
I like the idea of beng able to magically silence output bufers using host
support (as I said before), but I think that silcence detection on input
should be optional if its available at all. Something akin to what we had
for connected-ness would be aceptable: buffer esists, its full of -200dB
noise, theres a flag set somewhere that you can read if you like that
sort of thing.
