◆ handleNoteOn()

virtual void MidiKeyboardState::Listener::handleNoteOn ( MidiKeyboardState source,
int  midiChannel,
int  midiNoteNumber,
float  velocity 
)
pure virtual

Called when one of the MidiKeyboardState's keys is pressed.

This will be called synchronously when the state is either processing a buffer in its MidiKeyboardState::processNextMidiBuffer() method, or when a note is being played with its MidiKeyboardState::noteOn() method.

Note that this callback could happen from an audio callback thread, so be careful not to block, and avoid any UI activity in the callback.

Implemented in MidiKeyboardComponent, and MidiMessageCollector.

◆ handleNoteOff()

virtual void MidiKeyboardState::Listener::handleNoteOff ( MidiKeyboardState source,
int  midiChannel,
int  midiNoteNumber,
float  velocity 
)
pure virtual

Called when one of the MidiKeyboardState's keys is released.

This will be called synchronously when the state is either processing a buffer in its MidiKeyboardState::processNextMidiBuffer() method, or when a note is being played with its MidiKeyboardState::noteOff() method.

Note that this callback could happen from an audio callback thread, so be careful not to block, and avoid any UI activity in the callback.
