there are six filter chips on the board. 1 for each voice. if you press one note it would only use 1 of them. if you release the note and pressing another key, another voice (not the same) will be played. so if you trigger 6 keys in just a normal order you can identify the damage voice if. if you open the case you will see that a little led is lighted up for each voice that is played (so in fact there are 6 red led's bellow the filter chips)
just enable the arpeggator and set a slow arpeggio speed. then you will see that the 6 led 's are blinking in a linear order. (this works only in poly mode, on unisono all led's are lighting up)

Hi brainslayer,
Thanks for the quick reply. Just to make sure I understand you correctly, If
it were the chip itself I would hear it only in poly and not unison mode? Or,
are you saying hold down six notes in poly mode and it would affect only one of
the notes? My apologies if I'm being thick-headed here.
