I have an old Korg T2 which has started making weird electronic sounding notes with very long sustain. I am new to this machine and I don’t know if this is a programming issue or a faulty board or hardware. All pre-loaded voices sound the same - like bad sci-fi effects. Does anyone have any ideas or suggestions?
Look at page 33 on for power on tests and initialization proceduree. Of service manual below.
Here is a great synth manual link for you
