Yes, exactly - minor/major and modes in 12TET (as well as pentatonic but that's just major/minor with fewer notes).

What would be interesting with this synth (something other synths, like my Korg Monologue, can do) is being able to tune to different temperaments, i.e. not 12 TET - for this synth especially, since 12 TET was rarely used in the medieval period in favour of pythagorean or meantone tuning.

Thanks for elaborating. I should have been clearer that I was just quoting the docs and have no idea what I’m talking about. Your comments have given me some interesting things to read (listen?) up on, later :)

If you like synths/electronic music, and you're interested in listening to music in other temperaments/tunings, check out the artist Sevish. He also designed a web app for creating alternate tunings: https://sevish.com/scaleworkshop
