Hello everybody, I´m trying to repair an SY77, that when I got it was stuck in untility-mode. It freezes when one of the "mode"-buttons is pressed, so I cannot even enter the test-mode. Furthermore the wheels dont´t have any effect on the sound, but send midi-data. Anyone who experienced an similar problem or could provide any suggestions? best regards moe
