I have a strange bug happening these days: When my live set has been running for quite a while, sometimes the tempo becomes crazy (like four times the speed) for a few bars.
Also, the other day, in the middle of a show (!), all of a sudden, my audio card wasn't recognized anymore! I had to restart both the computer and the card a few times for things to go back to normal...
I use a Powerbook G4 1.33 running Live 4.1.4, with an M-Audio Firewire 1814 (with the latest driver), and a Roland SPD-S to control the scenes.
If anyone could help me, it would be wonderful!
