◆ handleNoteOff()

virtual void juce::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.

Implemented in juce::MidiMessageCollector.

◆ handleNoteOn()

virtual void juce::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 juce::MidiMessageCollector.
