## Detailed Description

This class handles the logic for remapping MIDI note messages from multiple MPE sources onto a specified MPE zone.

Definition at line 107 of file juce_MPEUtils.h.

## Constructor & Destructor Documentation

## ◆ MPEChannelRemapper()

juce::MPEChannelRemapper::MPEChannelRemapper | ( | MPEZoneLayout::Zone | zoneToRemap | ) |

## Member Function Documentation

## ◆ clearChannel()

void juce::MPEChannelRemapper::clearChannel | ( | int | channel | ) |
| noexcept

Clears a specified channel of this MPE zone.

Definition at line 219 of file juce_MPEUtils.cpp.

## ◆ clearSource()

void juce::MPEChannelRemapper::clearSource | ( | uint32 | mpeSourceID | ) |

Clears all channels in use by a specified source.

## ◆ remapMidiChannelIfNeeded()

void juce::MPEChannelRemapper::remapMidiChannelIfNeeded | ( | MidiMessage & | message,
|  | uint32 | mpeSourceID )
| noexcept

Remaps the MIDI channel of the specified MIDI message (if necessary).

Note that the MidiMessage object passed in will have it's channel changed if it needs to be remapped.

Parameters

  message | the message to be remapped
  mpeSourceID | the ID of the MPE source of the message. This is up to the user to define and keep constant

Definition at line 168 of file juce_MPEUtils.cpp.

## ◆ reset()

void juce::MPEChannelRemapper::reset | ( |  | ) |
| noexcept

Resets all the source & channel combinations.

Definition at line 213 of file juce_MPEUtils.cpp.

## Member Data Documentation

## ◆ notMPE

const uint32 juce::MPEChannelRemapper::notMPE = 0
| static

Used to indicate that a particular source & channel combination is not currently using MPE.
