The little red metronome tab has fallen off my Optigan® disc. What should I do to make sure I stay on the beat?
The best way to replace those red tabs is to simply buy a red permanent Sharpie pen and color over the appropriate metronome window. It works fine, and shouldn’t rub off. If you desire maximum redness
The overall volume seems a bit weak. What can I do?

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?
Often this problem can be cleared up by pressing the keys quickly and repeatedly. If this doesn’t work, you might try getting inside the thing and cleaning any gunk that may have gotten in between the
