Facility to use microtonal scales via Scala

[gogins]

The immediate and obvious use for this facility is for super-drone type pieces.

I'm not sure what-all belongs in this enhancement, or where it goes (Csound UDOs, CsoundAC C++ code, JavaScript code). Possibilities:

• [ ] Embed Scala file in a piece, then adjust MIDI key numbers to the scale in the Scala file (i.e. use fractional MIDI numbers).
• [ ] Supplement generative procedures with the use of Scala files by adjusting generated MIDI key numbers to a scale.
• [ ] Supplement generative procedures to directly generate Scala pitches.

As with maqam, with microtonal scales there should be some sort of "modulation," which will generate large scale changes of feeling and structure. How to identify and code these possibilities?

Strudel actually has already a pretty good facility for using alternative tuning systems, the tune pattern. For now I will use this, I may adapt it for modulation.
