[PD] New "fast-forward" message

[Josh Moore]

this sounds interesting. i've also successfully written to an array. i've
always liked this idea, it makes no sense to compute something over and
over again if you already know what's going to be computed. playing back a
bit stream from RAM is always going to be faster.

i can have some fun with this and i know exactly the application to use it
for as i've (ab)used this sort of "render to sample" feature in Renoise.
