I asked for this when I got my H9 Max years ago. There’s plenty of interest, trust me. It’s insane that I am still using a DigiTech Harmony Man for proper triad voicing in 2024.
Boss GT-1000 can do it, but the tracking is a joke. I just set it up and it’s really sad that I can perfectly define my scales but it sounds horrible because the harmost effect is garbage.
I would immediately buy an H90 if you’d add user scales. Without custom scales, harmonizers aare extremely limited.
Bonus points for high pass filter mode so you can chug lower notes and harmonize higher notes.
