Robo2k Posted April 21, 2011 Share Posted April 21, 2011 Why does Logic stuff all my Virtual Instruments on a single Core when there are 3 other cores (7 with hyperthreading) doing nothing? I know about the Apple document on distribution of FX/Plugins on AUX chains for CPU balance. but this doesn't seem to work with AU VIs. See my Image attached below: I am playing simultaneously 4 synths on 4 distinct tracks with no plugins. Core number 8 is maxed out (CPU window in the lower right corner) and all the others just idle. At 4-note polyphony things start to get a little ugly: cracks and pops. I am unwilling to augment the buffer (and latency) because my computer still has huge reserves that remain inexplicably unused. Clarification: This is LP 9.1.3 and all VIs are at their most recent version. Link to comment Share on other sites More sharing options...
