So far I have done the following:
~ Plugged it in and tried playing a few notes - there was sound with a few keys, but it only registered the same note each time and on different keys and constantly alternating keys. Some of the slider controls affected the sound (Attack, release, and decay), but others were unresponsive.
~ I then attempted to run diagnostics using the lower function and program select buttons. However, I was unable to engage the lower function LED rendering a diagnostic scan impossible (at least from what I can understand).
~ When I turned the Polaris off and on again different sets of LED's were illuminated
My question is: could this be symptomatic of a dead battery/erased memory requiring a new set of batteries and MIDI sysex dump, or something much more complicated?
If anyone has any advise OR just wants to buy this broken synth from me to fix it themselves contact me.
Thanks,
Chris
