[sdiy] MIDI too fast?

[cheater cheater]

Grant,
I wonder if it's possible to CV/Gate a JX3P. This sort of interface is
pretty much the only thing that will do what you expect it to do. If
so, you can use Volta and you're fine.

Cheers,
D.

P.S. MIDI is a terrible standard that kills musical expression. :^)
