controlling killing sound log message

[rbnpi]

Just been writing a midi-player program for Sonic Pi which involves starting (long) notes and killing them after the required duration. It works well, and I have it working with 16 input channels, including seperate arrangements for channel 10 (percussion). However each note killed produces a log message killing sound nnnn, and it completely swamps other log messages. Would it be possible for this to be controlled by the use_debug flag, so that it could be switched off as required. (or a separate flag like use_osc_logging, but I think it would be OK to include with the debug flag).
