CNTRLR, MonoMixer   :   Significant changes to CNTRLR mode selection routines, as well as mode definitions (thinned some things out).  Added some DelayMode() defs for session to weed out buggy button lighting from ClipSlotComponent.  Shortened preexisting DelayModes.  Added implicit arm coloring for MonoMixer, and added appropriate defs to CNTRLR Map.py.  Also fixed SplitMode display issue for MonoInstrument (mode definition problem).
