The only major functional change is that the Track now needs to know whether it's active or not, in order to listen to the keyboard (or not). There are some bugs exposed/created by this, mainly: * KeysWidget sometimes shows phantom notes. Those do not actually exist as far as debugging has revealed and do not play in the synth. * The keyboard can lock up Piano when rapidly pressing keys. This appears to be a HashMap bug; I invested significant time in bugfixing but got nowhere.
