Use commands and feedback
The library exposes commands and feedback in a human-readable and object-oriented structure. Feedback is published as streams that you can subscribe to. This uses the Observable object from RxJS.
conn.master.setFaderLavel(0.5);
conn.master.input(5).solo();
conn.aux(3).input(2).mute();
conn.master.faderLevel$.subscribe(value => {
// ...
});
All available command and feedback streams are described and listed in these docs.
