Ableton Forum

when i push it to the limits :

12 Rewire tracks
1 FM-7
1 PRO-53
2 MIDI
1 RETURN TRACK
2 AUDIO

non Ableton plug-ins: 1*WAVES REINESSANCE EQ, 2*C4, 1*PAZ ANALYZE,
1*OHMBOYZ DELAY, 1*PSP NITRO

48/24, 1 GB RAM, WD 120G 72000RPM, 800 FSB, AUDIOPHILE 24/96 m-audio

live is probably designed to prioritise audio perfmormance over interface performance.. in a different dimension, the situation would be that live would not let you run as many plugins/effects but always have a smooth user interface... oddly enough i would choose the latter.
