Orcoa Organ

Remember in the 1960's when you lived in Italy and had a hip apartment that included a space-age reed organ?!

Neither do I, but I bought this for a song used and tuned it into my 11-Limit "Peregrin" scale (see below).


While the 12-tone tuning is useful and intuitive, I made the triad buttons match the tuning (even though these "triads" are not emphasized or really even relevant to the tuning).  To be honest, they sound pretty horrendous, but I've seen toddlers make cool circus music with them, so, that's cool.  Besides, this way, if someone says JI sounds beautiful and pure, you can play them, say, a Bbm7 (7-Limit) on the keyboard.  But if they say JI sounds awful and out of tune, you can play them some of these 'triads.'   It's important to reinforce preconceptions.  You were right along!!
