22:12 | Removed useless samples and test csound files now that we're no longer using csound check-in: 680f187463 user: brian tags: develop | |
22:09 | Replaced csound support with midi support check-in: 0c3fb3e27f user: brian tags: develop | |
22:08 | Successfully got the program to output a MIDI file instead of a csound score Closed-Leaf check-in: befd61cab9 user: brian tags: feature/midi | |

01:39 | Altered the sample-based instruments to ine Csound string formatting instead of a billion if clauses to choose what file to play check-in: 4f872339ff user: brian tags: develop | |
Changes
