Hi Larry,

It's always been my understanding that the SX was a preset version of the
Xa.  I had one many moons ago.  I know that they made two versions of the
case.  One in black and gray, somewhat like what the X looks like, and one
in the black with blue lines like the Xa and 8.  I don't know if they
changed the insides.

The friend that I gave the SX to has problems keeping it in tune.  I
regularly have her visit a friend of mine that tunes it up for her.  Your
problem may be that your voices are too far out of tune for the synth to
auto tune.  Just a guess.

I replaced the dip switch on my Xa because it was messed up.  They get old.
Mine was keeping voices from turning on.  It's a pretty simple fix.  On
the Xa the dip switch is on the control board (the one with the knobs for
the front pannel).  Any proper size dip switch should work fine.

        It sounds like you're possesed.  You better watch out,
               they burn people around here for that...
