Appium automating all the musical things. This is a more modern version of https://github.com/jlipps/lxjs.

A score is represented as one long string with notes separated by spaces. Notes are a combination of a note value and a length, potentially with an up-or-down octave notation. For example, c8 means to play the note C as an 8th note. In addition to music notes, drum values (like h for hi-hat) and rests (r) are permitted. Really anything an instrument defines!
