I
don't know about OTR keyboard (does this stand
for Orchestrator? which is actually Multiman) but in these
'organ-style' keyboards the sound is generated by TOS (Top Octave
Synthesizer chip which generates all 12 base frequencies) which are
then divided down by divider chips for lower octaves, one for each note (12
altogether). In my Performer this divider chip is TDA1008, I bet one of your
dividers is either dead or malfunctioning. You can try swapping the C note
divider (should be the first one from left) with another one and see if the dead
note moves to another note.
Cheers,
Margus

I fixed the original problem with the synth, and it worked for about
two days. Then the C note went out, all 5 octaves. Any suggestions
about what might be wrong?
Thanks-
