Clever interpretation of these ON-OFF events gives us many new possibilities to expand the expressiveness of the instrument.

    This part of the code simply obtains the sustain ONOFF event and the moment it occured. The ONOFF event is the event of releasing the previously pressed pedal. The moment of this release is stored in the variable 'sustainONOFF_ts' and can then be furtherly used to analyse for how long the sustain has been pressed.
