## Detailed Description

This class represents the current MPE zone layout of a device capable of handling MPE.

An MPE device can have up to two zones: a lower zone with master channel 1 and allocated MIDI channels increasing from channel 2, and an upper zone with master channel 16 and allocated MIDI channels decreasing from channel 15. MPE mode is enabled on a device when one of these zones is active and disabled when both are inactive.

Use the MPEMessages helper class to convert the zone layout represented by this object to MIDI message sequences that you can send to an Expressive MIDI device to set its zone layout, add zones etc.

## Constructor & Destructor Documentation

## MPEZoneLayout() [1/2]

MPEZoneLayout::MPEZoneLayout | ( |  | ) |

noexcept

Default constructor.

This will create a layout with inactive lower and upper zones, representing a device with MPE mode disabled.

You can set the lower or upper MPE zones using the setZone() method.

  setZone

## MPEZoneLayout() [2/2]

MPEZoneLayout::MPEZoneLayout | ( | const MPEZoneLayout & | other | ) |

Copy constuctor.

This will not copy the listeners registered to the MPEZoneLayout.

## Member Function Documentation

## operator=()

MPEZoneLayout& MPEZoneLayout::operator= | ( | const MPEZoneLayout & | other | ) |

Copy assignment operator.

This will not copy the listeners registered to the MPEZoneLayout.

## setLowerZone()

void MPEZoneLayout::setLowerZone | ( | int | numMemberChannels = `0`,
|  | int | perNotePitchbendRange = `48`,
|  | int | masterPitchbendRange = `2`
| ) |  |

noexcept

Sets the lower zone of this layout.

## setUpperZone()

void MPEZoneLayout::setUpperZone | ( | int | numMemberChannels = `0`,
|  | int | perNotePitchbendRange = `48`,
|  | int | masterPitchbendRange = `2`
| ) |  |

noexcept

Sets the upper zone of this layout.

## getLowerZone()

const Zone MPEZoneLayout::getLowerZone | ( |  | ) | const

noexcept

Returns a struct representing the lower MPE zone.

## getUpperZone()

const Zone MPEZoneLayout::getUpperZone | ( |  | ) | const

noexcept

Returns a struct representing the upper MPE zone.

## clearAllZones()

void MPEZoneLayout::clearAllZones | ( |  | ) |

Clears the lower and upper zones of this layout, making them both inactive and disabling MPE mode.

## processNextMidiEvent()

void MPEZoneLayout::processNextMidiEvent | ( | const MidiMessage & | message | ) |

Pass incoming MIDI messages to an object of this class if you want the zone layout to properly react to MPE RPN messages like an MPE device.

MPEMessages::rpnNumber will add or remove zones; RPN 0 will set the per-note or master pitchbend ranges.

Any other MIDI messages will be ignored by this class.

## processNextMidiBuffer()

void MPEZoneLayout::processNextMidiBuffer | ( | const MidiBuffer & | buffer | ) |

Pass incoming MIDI buffers to an object of this class if you want the zone layout to properly react to MPE RPN messages like an MPE device.

MPEMessages::rpnNumber will add or remove zones; RPN 0 will set the per-note or master pitchbend ranges.

Any other MIDI messages will be ignored by this class.

## addListener()

void MPEZoneLayout::addListener | ( | Listener *const | listenerToAdd | ) |

noexcept

Adds a listener.

## removeListener()

void MPEZoneLayout::removeListener | ( | Listener *const | listenerToRemove | ) |

noexcept

Removes a listener.
