Changes In Branch develop Through [f8034c7dfb] Excluding Merge-Ins
This is equivalent to a diff from 689adc054e to f8034c7dfb
|
2011-11-27
| ||
| 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 | |
|
2011-11-17
| ||
| 19:55 | Removed leftover csound function lines that got printed. Also disabled ipdb so I get concise stacktraces. Also made program crash when your score pointed to a non-existant node. Previously that just generated an invalid MIDI file (somehow...) check-in: f8034c7dfb user: brian tags: develop | |
|
2011-11-16
| ||
| 00:14 | If I move from csound to midi I should actually rename function with 'csound' in the name check-in: 872ae93059 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
| ||
| 23:50 | Program generates a render order for the instruments based on their sync order check-in: 689adc054e user: brian@linux-85dd.site tags: master | |
| 22:34 | Added lexical support for parens instead of quotes for chords, cleaned up the yacc parser, added lex tokens for syncopation check-in: 702d933446 user: brian@linux-85dd.site tags: master | |
