Discussion about the Korg PolySix synthesizer

Did you check all of the connectors?  Was your CPU board a victim of 
the battery leak and was it repaired well?  Are you saying the magic 
words?

My PolySix seems like it's ready immediately once I turn it on.  Of 
course, it take about 10 or 15 seconds to power on everything else, 
so, perhaps mine takes the 10-15 seconds the others have mentioned.

Good luck!
