Recently Beat Kaufmann magnanimously posted some close, mid, and far iterations for the Convolution Reverb, and initial tests sounded great.
But I think I was naive as to the power I would need.
I had hoped to assign a close, mid, and far to each instrument on three separate busses per instrument. So flutes would get three, oboes three, etc. It would have added up to about 16 x 3 Convolution Reverbs.
Well, not even close. Flutes and Oboes sounded great, but by the time I got to clarinets, the stuttering and overloads began. The Play key command got slower, with about a two second lag time.
When I muted some of the VI Convolution Reverbs, performance improved, so I'm certain they are the cause. Also, the right-most CPU column maxed out, with the other columns a quarter to a half high.
The song load has Logic at about 2.1 GB Virtual Memory. 16 GB of memory in the Mac, Logic 9.0.1, OS 10.6.1, on a Mac Pro 8-core 2.8. Buffer setting in Logic of 1028.
Any chance I'm doing something wrong? If not, I guess I'll have to go back to that universal bus method.
