here's the deal....

my m1000 only plays 2 voices

after a reset, recalibration, etc it still plays 2 voices

when i go to ext function 5 (unit number) and set it to 1 or higher, suddenly all 6 voices are
available

it's not in group mode, nor in unison mode and only has midi in connected

i can't seem to get it back to its original default settings

any suggestions
