The Yamaha AN1x Synthesizer mailing list

Hello,

I have an AN1X that's been sitting around for a few years. I used to gig with it live and then after a show in Europe it sort of konked out. I've decided to re-investigate the issue now as I'd like it to work.

Currently, for each patch on the synth, certain keys won't play in that patch and what keys those are change from patch to patch. On some patches where it's particularly bad you can keep pressing one key down on repeat. Sometimes it'll play and then on another press it won't. It's random.

I've read online that this happens in Single Layer mode. When in each patch I select the Layer mode to be Unison, it'll play all the keys within the patch totally fine.

I've seen some folks opening their synths, checking all the internal connections to see if they work and then after re-assembling it again saying it worked totally fine but that seems a bit chance to me.

If anyone out there might have a solution this let me know. FYI, I've done a Factory Reset to see if that would fix the problem but it didn't.

If the AN1X was an old analog synth I would say that the problem is obviously one or two of the voice cards have failed.
