The GX has all its voice cards in 80 pin 0.1" card edge sockets, so swapping
round a bad card is simple.

I'd be interested to find that out too.
The GX is odd. I assume it keeps a list of free voices in least recently
used order, assigns the voice at the head of the list to a new note and
sends that voice to the end of the list when it is released.
After an initial clear, for a repeated single note, it starts at voice 2,
then cycles thru 3,4,5,6,7,1, back to 2...
If you play an overlapping note before the first cycle thru 7 has complete,
it plays the second note on the next voice.
But once thru the cycle of 7, a second note will always be on voice 8.
That suggests to me that the intial state of the LRU list is
2,3,4,5,6,7,8,1.
Once you go through the first cycle, it skips voice 8, leaving 8 at the head
of the LRU, where it stays until at least two notes are overlapped.
One particularly odd thing is that if voice 8 has been brought in during a
cycle of single notes, on release it seems to put both voices 8 and 7 at the
end of the LRU list, so voice 7 is not used as soon as you'd expect.
As you might imagine, mimicking this behaviour precisely in software is
going to be a fun job.
