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.
