I'd love to post my findings about OSX / Logic 9.1.1 / Apogee Duet to a specific forum area, so we could compile information about using the Virus Ti with specific hardware.
Anyone else interested in being able to check into a forum area that is designed per hardware/software specs?
Here's the rules I've been working with, and I've had mixed success:
VIRUS RULES:
set I/O buffer size to [128]
access and apogee recommend 128
process buffer [small]
plugin latency compensation must NOT be set to off
low latency mode should be [disabled]
general / pref / global settings / cycle = [1/96]
enable smooth cycle
project settings / pref / audio /
[enable] playback preroll
OSX 10.6.4 / 2 X 2.66 Dual Core Intel / Logic 9.1.1 @ 32bit / Virus 4.0.5.01
