The goal is a clean, MIDI piano player available on both iOS and web. At the moment, I wouldn't expect most functionality to work or to perform smoothly. Sorry about that, but hopefully this gives you an idea of what's in store.
Tip: If you've ever used GarageBand or Logic, try playing the piano using the piano-keyboard layout you're familiar with. Octave changes are also supported with Z/X. Panning is supported with arrow keys, and resizing if Shift is held. Also, try searching for "Chopin" (that's the only other song uploaded on here).
