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.
I plan on opening up the synth to check for a loose ribbon connector and to clean some contacts. Just wanted to add a reply in case anyone else searches this topic (like I just did) and is looking for possible answers.
BTW, the AN1x I just picked up is a mint condition unit. First owner used it once or twice and then kept it in a closet for the past 10 years. Everything was in perfect like new condition...synth, power supply, manuals, box. Software OS version is v1.03.
