Hello! So I am trying to design a data structure that is a list of musical events that are composed of duration, amplitude, and a list of four pitches to be assigned to SinOsc's . When I was constructing the idea, I called the atomic units of the lists "events" not knowing that there existed an Event class in chucK. When I researched the Event class, however, I become confused as to whether or not extended that class would be appropriate for what I am trying to achieve. I was wondering if someone could advise me the easiest way of going about creating a list of lists of two ints and a list: ["Event"Object1, "Event"Object2, ...,"Event"ObjectN] where "Event"Object[i] = [int amplitude, int duration, [pitch1,pitch2,pitch3,pitch4]] The idea is that one can simply iterate across the above list of "Event"Objects and assign a bank of four SinOsc's the pitchs 1 through 4; assign an envelope's gain to the amplitude, and advanced time by duration. I apologize if the above is an ugly articulation of my idea.
