ive just been playing on my ax73 and its suddenly lost half of its voices or something?

it should be 6 voices in poly-mode, 3 in dual and 1 in solo mode. now its 3 in poly and 2 in dual. its just happened.... i can hear it stealing a note on the second key of dual mode as well. is there anything i can do????? it was fine half an hour ago, and it hasnt been knocked or anything thing.

Have you tried turning off the power, pressing down on any socketed chips, and then turning the power back on?

yeah i was thinking that checking the chips are firmly in place would be the way to go, but its come back after a couple of turn off/on's. phew.... i will open it up tomorrow if i get the chance and have a look inside. i'm pretty sure its a CEM based synth, so its one voice per chip.

Yeah my guess is "chip creep". It is a problem caused by thermal expansion and contraction of the entire machine. Over time this movement tends to dislodge socketed components, causing strange problems with no appearent cause. I suppose it could also be a lot of other things going on, but loose IC's get my vote.
