A long time ago I needed something that would toggle between 1 and -1 at audio rate whenever its input decreases in value (as would happen when driven by a [phasor~]). This is what I came up with:

The blocksize has to be small enough to accomodate the highest frequency toggling that you need to support.

I was convinced that this was the only way possible, and so was completely surprised when I stumbled across this:
flipflop2~.pd
Seems so obvious in retrospect!

Edit: OMG, I posted a similar solution 3 years ago and forgot about it. I'm now accepting nursing home recommendations.

let me recommend my ELSE externals instead of a nursing home

[pimp~] is [phasor~] + [imp~], which sends impulses at period transitions. The [toggleff~] (toggle flip flop) is an audio rate flipflop that alternates between 1 and 0.
