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.

◆ Zone

Constructor & Destructor Documentation

◆ MPEZoneLayout() [1/4]

juce::MPEZoneLayout::MPEZoneLayout ( )
default

Creates a layout with inactive upper and lower zones.

◆ MPEZoneLayout() [2/4]

juce::MPEZoneLayout::MPEZoneLayout ( MPEZone  lower,
MPEZone  upper 
)

Creates a layout with the given upper and lower zones.

Definition at line 26 of file juce_MPEZoneLayout.cpp.

◆ MPEZoneLayout() [3/4]

juce::MPEZoneLayout::MPEZoneLayout ( MPEZone  singleZone)

Creates a layout with a single upper or lower zone, leaving the other zone uninitialised.

Definition at line 31 of file juce_MPEZoneLayout.cpp.

◆ MPEZoneLayout() [4/4]

juce::MPEZoneLayout::MPEZoneLayout ( const MPEZoneLayout other)

Definition at line 38 of file juce_MPEZoneLayout.cpp.

Member Function Documentation

◆ addListener()

void juce::MPEZoneLayout::addListener ( Listener *const  listenerToAdd)
noexcept

Adds a listener.

Definition at line 184 of file juce_MPEZoneLayout.cpp.

◆ clearAllZones()

void juce::MPEZoneLayout::clearAllZones ( )

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

Definition at line 97 of file juce_MPEZoneLayout.cpp.

Referenced by juce::MPEInstrument::enableLegacyMode().

◆ getLowerZone()

MPEZone juce::MPEZoneLayout::getLowerZone ( ) const
inlinenoexcept

Returns a struct representing the lower MPE zone.

Definition at line 143 of file juce_MPEZoneLayout.h.

◆ getUpperZone()

MPEZone juce::MPEZoneLayout::getUpperZone ( ) const
inlinenoexcept

Returns a struct representing the upper MPE zone.

Definition at line 146 of file juce_MPEZoneLayout.h.

◆ isActive()

bool juce::MPEZoneLayout::isActive ( ) const
inline

Returns true if either of the zones are active.

Definition at line 164 of file juce_MPEZoneLayout.h.

◆ operator!=()

bool juce::MPEZoneLayout::operator!= ( const MPEZoneLayout other) const
inline

Definition at line 139 of file juce_MPEZoneLayout.h.

◆ operator=()

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

Definition at line 44 of file juce_MPEZoneLayout.cpp.

◆ operator==()

bool juce::MPEZoneLayout::operator== ( const MPEZoneLayout other) const
inline

Definition at line 138 of file juce_MPEZoneLayout.h.

◆ processNextMidiBuffer()

void juce::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.

◆ processNextMidiEvent()

void juce::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.

noexcept

Removes a listener.
