FYI, I have the G4 500 with 320mb ram. I added 4 D-verbs (someone once said these eat DSP for breakfast), and didn't run into the dreaded "you are running out of CPU power" until i added a 5th. I also added 4 comps. I'm getting the filterbank from McDsp which is supposed to be DSP friendly. Maybe someone should make a McVerb. haze
