Since you said "batterys" I'm assuming you are talking
about C cells and haven't got a lithium cell installed for the memory. The only
time I've seen this problem, the C cells really were not making good contact and
the memory would get wiped if the synth was bumped. If you haven't added a
lithium cell for memory backup, I would suggest this as a first step. The
modifications needed would depend on which version of the MK1 you have (#1-no
lithium cell, no solder pads on the board #2-no lithium cell but board has
solder pads where it would eventually go #3-Solder pads and an old dead
lithium cell already there). I certainly would NOT solder in a battery. Install
a socket for a CR2032 instead. If you've got a soldering iron, we can talk you
through this.

Subject: [korgpolyex] MK1 MEMORY PROBLEM
Hey guys! I bought a used MK1 a couple of years back. It worked great, but
every once in a while would lose the factory presets when unplugged for an hour
or so while gigging, reverting to unusable "noise" sounds. I am using fresh
batterys. Since I have the factory patch SYSX I would simply dump it back in
after the show, but a few months ago it stopped responding to the dump. After
the load the diplay will say "good" but the weird "noise" presets will still be
there. Anyone else encounter this issue?
