Recently I ranted about various (mainly historical) temperaments and some interesting instruments which provide tunings other than equal temerament alone (german language, I apologize).

Synthtopia shared an article featuring two videos of Dolores Catherino. In the first video, she talks about the controllers she is using. The second video contains her polychromatic composition »Heterodyne Horizon«. It’s not exactly my tast of music, but it shows the possibilities anyway.

BTW: I was surprised that the ROLI Seaboard works with such a course pitch resolution.
