I'm noticing this tendency of Maschine freezing after a few minutes of use in Ableton, specifically in the Mackie Control Template.
The first sign is that Ableton stops receiving midi signals (no yellow flashing dot on the top right of Live)
Macbook Pro 17" OSX Lion, so the very latest os
Maschine 1.7.2 (or the newest one)
Anyone else noticing this?
