Not sure what the correct terminology is, I have practically no music theory and I’m a synth noob.
All quantizers that support just intonation that I could find appear to have fairly static tuning, which seems to defeat the purpose. Is there a polyphonic quantizer out there that allows you to constantly update the root note and it automatically adjusts the tuning accordingly? Even better yet would be one that determines the root on its own, perhaps by the lowest note, or else a particular channel. If nothing is out there, are there any developers interested in the challenge?
