I have looked at the docs for Ess and Minim sound libraries, and all the sample code I see there starts sounds playing in the setup() function of Processing.

It seems you can play samples this way, but it doesn't seem as though you can work with samples interactively, where you might launch sounds based on timings, counters, mouse clicks, etc.

Is this kind of interaction with sound samples possible in Processing? If so, where might I locate some sample code from which to learn?

Thanks,

I'm doing something similar to that but I am using Sonia instead of Ess. Each square triggers a sample when you click it. Depending on where you hit the square, it will change the rate and panning of the sample.
