purely an abstract question, but.. any modules out there that deal with different scales, tuning scales, as in Egyptian and Indian scales. micro tunings.

Many quantizers let you define your own scales by choosing a selection of tones from the standard 12 semitones. Some quantizers also work with microtonal tones. The ADDAC207 Intuitive Quantizer is an example of a full-featured quantizer with microtonal options.
