Connect OSMD to heartbeat

This version uses the MusicXML parser and the OSMD modules of WebDAW and heartbeat for MIDI playback.

• When the song plays active notes will light up in red
• When you click a note, the note will play
• When you control click a note, the playhead will move to that position
• You can draw a selection rectangle on the score to select a loop
• The ENTER key on your numpad will play/pause song, the 0 key will stop the song
