I tried to get the frequencies contained to a reasonable range but this -erm- structure doesn't mix so well with being reasonable :-). Actually it doesn't seem to mix well with readability, maintainability and good stylistic taste either.

It does have some rather interesting implications for function syntax, this works;

e => foo(([1, 4, 7, 10, 13])[Std.rand2(0,4)]);

and it's nice, it's even somewhat logical, but I'm not at all sure the language specs make it clear that it *should* work. In a way two parameters are send to the function but ChucK figures out the UGen should be connected to the return value of the function. Interesting.

Yours,
Kas.
