hi

i know there's a way to cut down the sample granularity- down to even 2 bit, with pd, and i think it's even been discussed in this forum not too long ago- but i can't find it.

can anyone remind me of how to 'downsample' like this?

Yo,

If you want to do a 'downsample' check out the built-in [samphold~] object. If you put a slow squarewave into the right hand inlet you can get nice bitcrunching. If it's not time-domain quantising that you want to do, but would rather 'alias' the wave - reduce the resolution of the wave in terms of the number of unique positions that a sample can be in vertically (e.g. '16 bit', '8 bit', '4 bit' etc.) at each sample point, then try out the builtin [wrap~] object. If you want GOP abstractions that do these two things check out:
