the main issue is the pyramid is midi/whole note focused, (i.e. you cannot have fractional pitch)
so microtones have to be done as note + pitchbend, and if you’re using a single midi channel that means it’s monophonic, and there is no support on the Pyramid for multi channel data on a single track . (and it’d be a huge amount of work to do that!)
the reason the current ‘scales’ work, is they are all subsets of the chromatic scale.
(*) If I wanted to do this, what I would do is - get something like a Axoloti, rPI or Organelle,
connect the midi output from the Pyramid to it, and then implement a MidiFX on that box, that re-inteprets the midi to a new microtone scale - this could then use pitchbend on multiple channels etc.
(this approach works for other scales not based on the western chromatic scale too)
there are a couple of limitations
- they pyramid knows nothing of the scale, so the UI is tricky - it would only really make much sense if you used a controller that fed it midi in the same converted microtone scale - so you could ‘play it in’
- midi is limited to 127 notes, so with your 23 note scale, could only yield 5.5 octaves.
(*) I half remembering seeing a device you could buy that basically does this, but remember what it was called - perhaps if you google microtonal midi converter or something similar, it’ll pop up…
