@kd@yiff.life Made separate instances of my instruments for each voice, added a FL keyboard controller for each, set that up to make microtonal adjustments for each note, linked every controller to the appropriate pitch wheel and punched in the score like that.
Actually wrote this in a 12 tone scale too, but since there's 19 notes now you can do that while still maintaining a sense of inherent tonality, without having to impose strict harmonic rules to keep things together nearly as much.
