I am using the algo Reverb in Kontakt 6 instead of the convo, to save cpu usage. I have deleted all instances of the convo reverb for each instrument, and inserted algo in its place. I have a bunch, as it is an orchestral project. I'm using the Factory Library VSL inst's. Now, does this mean that each inst has a separate instance of the algo reverb? CPU is about 20-25% with several inst's playing (all the string groups, a harpsichord, a few solo winds and a little percussion). This doesn't seem too bad, and I have no problems with playback.
Should I instead route all inst's to an auxiliary channel, to save CPU? If so, how exactly do you do that?
