Constructor.

Member Function Documentation

applyRemapIfExisting()

bool juce::MPEChannelRemapper::applyRemapIfExisting ( int  channel, uint32  sourceAndChannelID, MidiMessage &  m  )

privatenoexcept

clearChannel()

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

noexcept

Clears a specified channel of this MPE zone.

clearSource()

void juce::MPEChannelRemapper::clearSource

(

uint32

mpeSourceID

)

Clears all channels in use by a specified source.

getBestChanToReuse()

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

reset()

void juce::MPEChannelRemapper::reset ( )

noexcept

Resets all the source & channel combinations.
