| 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 | |
