Hi,
Thanks for all the replies but as stated on my last post I think I
fixed the problem as I have used my AN1x for 2 days now without any
of the sounds going all weird on me. I don't know what I did to fix
it but it seemed to fix when I pressed the "assign" button while
powering on the AN1x.
If my synth starts behaving badly again then I will try the all the
instruction that members have told me to do to try and fix it.
Cheers
Arthur

general layout of your synth. Touch each IC in the right part of the
electronics (here the analog output circuit)with your fingertip, the
hotter one might be nearly dead. But some ICs like the voltage
regulators are normally hot. Of course avoid it when the mains
voltage is present, but on most synths there is an external DC
supply, and the voltages are low (9 or 12 V, 5V for the logic ICs,
even less for the DSPs or µPs).

a "cold spray" (available in electronic parts shops): cool down each
suspect chip when the sound goes wrong; if the problem disappears
you've found the failed device. Now the main problem is to find a new
one, in modern instruments you have a lot of specific ICs only
available by Yamaha (or other brand), if they agree to sell you
one....

said, a drifting IC chip or maybe a circuit that flakes out when it
gets warm. I have a novation KS-4 that does the same thing, its
irritating because I can use it for live shows anymore, cant trust it.
