P.S. Lucas: Yes, I do plan to work in Hertz for Just Intonation, mainly to develop computer improvisation (for duet with myself as thereminist).

I don't expect to use the Tonal Plexus in live performance, but rather, to demonstrate alternate tunings in my music theory classes.

Thanx Simon,

I learned why the Op wanted to use MIDI plus cents. At least now it makes sense to me “MIDI with decimals”.

I've always worked my scales just in Hertz totally unreferenced to the “Equal temperament”, that's why I didn't understand it.

If you want other tunings totally unrelated to 440hz why [mtof]?

because many scales, or better the references use cents as detuning amount from equal temperament. cent is also logarithmic and can therefore be used with mtof to get hertz.

but of course if he has a resource with hertz values for each scale, even better.
