Cool, this feels like OpenSCAD, but for music. I'm very visually oriented, so I don't think this would work for me (neither does OpenSCAD), but I really like the concept.
Take a look at the visual feedback section any try some of the examples, they may help. I play guitar a bit and came to realize that my understanding of chords and scales and some of music theory was very pattern based so I’m interested to see if that will translate to trying this intersection of music and programming with those visual aids.
