23-EDO is a bit of an unusual tuning, but actually works out quite well on the Lumatone keyboard. In this video I demonstrate a few different options for 23-EDO starting with a familiar-looking 4/7 keyboard with the white keys tuned to a mavila scale. I also mention a keyboard layout from Erv Wilson's 1987 paper "Multi-Keyboard Gridiron", which is available at the Wilson Archives on the Anaphoria website (https://www.anaphoria.com/keygrid.pdf). The .ltn files for these keyboard layouts are available at https://drive.google.com/drive/folder...
