[Beej]

I'm not sure if this is the best forum for this, apologies in advance.

I've been a fan of Harry Partch for some time and only came across this the other day. Cool ratio player that allows you to hear just intervals as you enter them, either as a scale or chord tones.

Cool for playing the tones laid out in Partch's work.
