like rand~, but driven by a ramp?

hi gang,

i'm hoping to be able to construct a repeatable audiorate noise thing that I can drive with phasor and the like, but I am drawing a blank in my fried lil' brain.

I am hoping to be able to do this simpler than scanning a random buffer, or stuffing a stash~, for instance.

it could also be a pseudorandom from fm'd cycle~s, something like that?

cheers
