Actually, I think that's plausible... The MKS-70 was
a mid-80s design.  Thinking back a bit, the generation
just before that (J106, etc.) didn't remember their
MIDI parameters at all; everything was either set by
hard-wired switches/jumpers, or had to be set at every
power up.  I'm guessing that on the JX series, they may
have put the MIDI parameters into a RAM separate from the
patch RAM, and if that RAM is a different type, it may
be more sensitive to power spikes.  Just a theory.
