is your psu large enough as its getting hotter it sounds like the voltage is dropping i had this problem with a faulty psu it would start after 5 minutes and the sounds would start to get distorted
psu are the biggest problem with any electronic equipment and wallwarts are the worst as everything is compacted into a plug size package
get another psu and try that first before suspecting the synth

> I realize this thread/topic is over a year old, but I recently got an AN1x again (had one a few years ago) and was experiencing this exact problem as stated in the original topic. Some patches sound normal for awhile and then suddenly sound thinner. After messing around with it for a bit trying to isolate the cause I'm 99% convinced this is a ribbon controller issue (specifically the Z axis). Applying pressure or tapping the ribbon cures the problem, but it can reoccur again after powering down and powering on.

Gosh, we had threads on this awhile ago... the Ribbon Controller always seemed a bit unpredictable.
I think the most common issue was was being able to tap the ribbon would cause it to 'hold' at that value rather than jump back to the default value and for others it would not work as advertised. It was an intermittent thing, and while some of us could reproduce the issue it was never under the same circumstances as another user, i.e. using different voices. And it seem to clear after a power on/off cycle.
Sound likes you've rediscovered this issue.
