1248/// General defined values to customize the behavior of parameter-to-MIDI mappings
1249///
1250///
1251///
1252/// If this flag is set and the value of the mStatus field is a MIDI channel message, then
1253/// the MIDI channel number in the status byte is ignored; the mapping is from the specified
1254/// MIDI message on any channel.
1255///
1256///
1257///
1258/// If this flag is set and the value of the mStatus field is a Note On, Note Off, or
1259/// Polyphonic Pressure message, the message's note number is ignored. The mapping is from
1260/// any note number.
1261///
1262///
1263///
1264/// Set this flag if the MIDI control should map only to a sub-range of the parameter's value.
1265/// Then specify that range in the mSubRangeMin and mSubRangeMax member fields.
1266///
1267///
1268///
1269/// Intended for Boolean typed parameters. When this property is set, it means that the
1270/// parameter's value should be toggled when the mapped MIDI message is received. For example,
1271/// if the parameter's value is currently TRUE, when the mapped MIDI message is received
1272/// the value changes to FALSE.
1273///
1274///
1275///
1276/// This property is useful when mapping a parameter to a MIDI Controller. When set, it
1277/// indicates that the parameter can assume only two values: on or off. For this reason, a
1278/// parameter associated with this property is typically Boolean. For example, if this
1279/// property is set for a parameter mapped to a sustain pedal MIDI controller, controller
1280/// values from 0 to 64 result in the parameter switched to its "off" state; controller
1281/// values from 65 to 127 result in the parameter switched to its "on" state.
1282///
1283/// This property works in connection with the kAUParameterMIDIMapping_Bipolar_On property.
1284/// The value of the kAUParameterMIDIMapping_Bipolar_On property
1285///
1286///
1287///
1288/// Determines whether the  "on" state of a parameter is mapped to the "on" or "off" state
1289/// of the associated MIDI controller. Only valid  if the  kAUParameterMIDIMapping_Bipolar
1290/// property is set.
