I've found that recording things in chuck is quite expensive
(computationally), so I would first try it without recording. And I
certainly wouldn't have four different recordings going on at once;
I've find some way to only have one thread recording everything.

I did a similar thing (in chuck) using fifteen generators. In my case
I had new generators wait until one was free, instead of stealing it...
but you can avoid the clicks if you can give the generator a few ms
notice before stealing it. When you notify a generator, have it do a
fade-out, then start the new info.

sporking is relatively expensive. When I tried to do my project (with
18.104.22.168, I believe), I ran out of CPU when I have five generators
going. With an array of objects (using whatever I wanted up to the
array size), I could do something like fifteen or eighteen generators.
Since chuck is so new, it's not very optimized.
