Each of the 128 MIDI key numbers can have its own value for polyphonic aftertouch. To respond to aftertouch for a particular key, your audio unit needs to support an additional parameter specifically for that key. The aftertouch parameter ID for a given MIDI key is equal to the MIDI key number plus 256.

Host applications can use these IDs to directly address these parameters without first discovering them through the AUParameterInfo mechanism (see the AudioUnitProperties.h header file) Each parameter is preceeded by a comment that indicates scope, unit of measurement, minimum value, maximum value, and default value. See the AudioUnitProperties.h header file for additional information that a parameter may report When displaying to the user information about a parameter, a host application should always get the parameter information from the audio unit itself. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ } {$ifc not TARGET_OS_IPHONE} // Parameters for all Panner AudioUnits const // Global, Linear, 0->1, 1 kPannerParam_Gain = 0;
