#include <MIDI_Inputs/MIDIInputElement.hpp>
The MIDIInputElement base class is very general: you give it a MIDI message, and it calls the updateWith()
method with that message.
Each instance must then determine whether the message is meant for them or not. This is often a very repetitive task, so that logic is best isolated in a so-called “Matcher”. The Matcher looks at the MIDI message, checks if it matches its MIDI address, for example, and if so, it extracts some data (such as the MIDI velocity value from the message). Then it returns whether it matched and the extra data as a “Matcher::Result” object. If the message matched, that Result object is passed to the MatchingMIDIInputElement::handleUpdate() method, so it can be handled there.
