Midi CC11 should be set to 127 as a default on the reinitialising of a GM type synth and is used in conjunction with other Midi data to simulate variations in Gain found during long held notes. CC11 has no effect on Audio Tracks. In BIAB, Reset Controllers are sent at the start of a generation sequence. In RealBand, it is up to the user to sort out Data problems such as the carry over of Midi settings from a previous song: eg: Bends, CC1 Modulations or Sustain, etc.
