I’ve always dreamed of a flexible microtonal piano roll. I realize that it’s likely challenging to implement something without a fixed number of pitches per octave, but it would be incredible and open up a lot of possibilities.
Even if it was confined to 12 pitches per octave, it would be really cool to have each pitch independently tunable for precise microtonal control.
My thought is that if you’re going to have a piano roll, why not open it up to further exploration of the pitch pallette? I mean there are a million piano rolls out there. How many of them are microtunable?
It would be awesome to get away from the arbitrary note names and intervals, and have the ability to input frequency ratios for pitches to explore just intonation. And perhaps a way to create equal temperaments within a given number as well.
