Discussion about the Korg PolySix synthesizer

Hello everyone after really finding out and fixing the prob with the 
controls..yes thanks alot to Old Crow and Johannes...
another problem showed up....as far as i can tell i din't damage
anything...so here is the prob..

when i turn on the synth all the osc turn on and the corresponding
leds on 366 as well..there is a weired sound coming out of the
synth...when i press a key only osc3 turn on and off, after a while
osc4 joins in and after another while osc5 as well...the others stay
on...i can't change to unison mode as well....after pressing the hold
button on and off all the osc leds go off.....when i press a key i get
weired sounds...osc1 seems fine osc2 as well osc3 is scratchy osc4
seems good but is lower than osc1+2..osc5+6 don't give any sound.. 

anyone had this problem before..i searched the group without result..

Tips would be apprechiated-...thanks in advance...
