I think we're talking about the same event. I had the year incorrect in
my notes.
I few years ago I tried to track down John Seng for a discussion /
interview about the GX1, but alas I found his obituary. I did learn from
Gary that John created the 'preset voices' for the GX1. That is, the tone
modules that have fixed resistors in them as opposed to the little
trimmers. He would set up a voice on the programming box, then the
engineer would record the resistance values of each trimmer to fashion the
fixed divider settings for the preset modules. Gary later did the same
thing for the CS-80 presets.
The 'amplication' was doubtless a pair of TX-III tone cabinets, made for
the GX1.
