{ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Supporting the kAUGroupParameterID_KeyPressure parameter indicates to hosts that your audio unit
supports polyphonic "aftertouch" key pressure.
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. For example, the aftertouch parameter ID for MIDI key #60 (middle C) is:
60 + kAUGroupParameterID_KeyPressure_FirstKey = 316
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ }
{ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following sections specify the parameter IDs for the audio units included in Mac OS X.
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.

// Mod Wheel) as well as MIDI status messages (such as Pitch Bend and Channel Pressure) and the
// MIDI RPN control messages.
// For MIDI status messages, use a value of 0 for the "channel part" (lower four bits) when setting
// these parameters. This allows audio units to distinguish these IDs from the 0-127
// values used by MIDI controllers in the first byte of status messages.
//
// The element ID represents the group or channel number.
//
// You can use the MusicDeviceMIDIEvent function to send a MIDI formatted control command to a device.
//
// You can use the SetParameter API calls, declared in the AUComponent.h header file, as follows:
//
// scope == kAudioUnitScope_Group
// element == groupID -> in MIDI equivalent to channel number 0->15,
// but this is not a limitation of the MusicDevice and values greater than 15 can be specified
// paramID == midi controller value (0->127), (status bytes corresponding to pitch bend, channel pressure)
// value == typically the range associated with the corresponding MIDI message (7 bit, 0->127)
// pitch bend is specified as a 14 bit value
// See the MusicDevice.h header file for more about using the extended control semantics
// of this API.
