I too am going to get one of these as my Polysix is right now just a
preset machine (hey, at least they are the presets I programmed into
it!).
I was having a similar problem where my patches would change randomly
and would usually snap back to what they were supposed to be if I hit
the bank/program button where they were stored. Battery was replaced
4 years ago and I had no problems for 3 1/2 years. Anyway, now the
patches all sound fine every time, but I can't edit anything except
the octave selection. So I will replace the IC32.
But, Question - isn't there a special tool for removing them rather
than using a (static-free) screwdriver? I want to be carefull not to
damage the board when I remove the old chip before putting in the
new. Or if there are any techniques I should know, that would be
appreciated.
Thanks,
