Hi,
right before my gig tonight I found that 2 of my a4 voices turn silent after 10 minutes or so. Did a calibration. Test mode on startup. Empty project. Nothing helps. When clearing a kit I can hear the init sound. But very short and low volume.
Crazy thing is. When I restart the A4 everything is fine. But after some time the oscillators seem to vanish.
Any quick ideas?? Shit.
