2011-11-27
02:56		Fixed chord support check-in: 8f28834102 user: brian tags: develop
02:26		Fixed a bug that prevented sharps and flats from working check-in: bf135b5321 user: brian tags: develop
02:03		Added a volume offset parameter to each instrument. Fixed a bug that kept instruments from always being rendered, and one that broke midi files. check-in: 821ac3e4d6 user: brian tags: develop
2011-06-12
20:32		Made some changes to the parser. Don't remember what. Leaf check-in: 87435601e4 user: brian tags: master
20:31		Create new branch named "develop" check-in: 9f4c4666c5 user: brian tags: develop
2011-02-10
