When I play the top most key on my Optigan, I hear one of the chord tracks bleeding through. What’s wrong?
Crosstalk! Learn to live with it! If you don’t have the test discs, the easiest way to hear the crosstalk is by pressing the top most key on the keyboard. Crosstalk changes with the weather, basically
Some of the keys on my Optigan don’t work. How do I fix this?
