the novice chucKster trying to navigate the Event class
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.

You probably don't want to extend the Event class for that. Events are ChucK's way of allowing you to sleep a shred for an indeterminate amount of time (until an "event" occurs and you call event.broadcast()/event.signal()). I recommend making your own distinct class for note events. class NoteEvent { float amplitude; dur duration; float pitches[4]; } (and probably a factory function to get closer to the event array syntax you mentioned) -- Tom Lieber http://AllTom.com/
