I read somewhere that there was a modification you could get that took
either a bigger EPROM or a daughterboard with more sockets, and
allowed you to switch samples with the resonance control.  IIRC the
lower two bits of the resonance value set which EPROM was selected -
obviously the difference it makes to the sound is tiny.

I'd love to get a hold of one of these, to work out what the mod is
and maybe copy it.
