I experience serious performance issues with M4L:
Create a new Live Set. Delete the MIDI track. Duplicate the audio track about 10 times. CPU load: 2% or so.
Do the same, but before duplicating, put a new M4L audio effect into the track. Now, with 10 empty M4L effects, the same 10 tracks use about 10% CPU!
How is that possible?? It does not really matter whats in the device, the device itself seems to be very resource-intensive.
Thanks for clearing this up for me....
