Check-in [f8034c7dfb]

Overview
Comment: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...)

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

If I move from csound to midi I should actually rename function with 'csound' in the name check-in: 872ae93059 user: brian tags: develop
