Gimmicky techniques such as upside-down and multiple discs are obvious, and hence pretty boring. As far as disc manipulation goes, I like to take two copies of the same disc and tape them together back-to-back so that the beats line up perfectly. This way you get some cool reverse echo effects on the drums. As far as actual performance goes, I often combine chord buttons to get a wider range of harmonic possibilites. Results vary depending on which disc you’re using, but generally you can get major 7th chords by holding Bb & Dm, F and Am or C and Em.

Those are sixths…
6ths: Bb + Gm, F + Dm, etc.
M7ths: Bb + Dm, F + Am, etc.
m9ths: Bbm + Fm, Fm + Cm, etc.
11ths: A + G, C + Bb, E + D, G + F
Those would work… I don’t have an optigan® 🙁
