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.
