Music processing in Linux: equal temperament, just intonation etc.
Can anyone point me in the direction of resources for music/sound processing in Linux? My specific target is to use my newly-acquired Raspberry PI as a demonstration tool for different tuning schemes, e.g. just intonation, or equal temperament. (If you don't know what these mean then trouble yourself no further!) I'd need some sort of keyboard input, probably, and some way of specifiying the tuning scheme details, and facilities for sounding chords and so on. My input source is a book called How Equal Temperament Ruined Harmony: And Why You Should Care by Ross Duffin, if anyone's come across this.
Is this a reasonable project, or am I just wasting my time, given that I'm starting pretty much from scratch?
