Ha, that was meant to be a joke. (A geeky joke, nonetheless.) I guess a linear phase all-pass would simply be a delay!

The fact is that you can make most anything you can imagine - but whether this produces a useful sound is another matter entirely of course.
Well, I've used them a good bit in Kyma for various oddball stuff, but I recently picked up DDMF's IIEQ Pro plug-in and as a result have been using it in mixing. It allows any band to be config'd as an all-pass and you can serial or parallell wire the bands. Chain a few together and shove it in a duplicate reverb return channel . . . .

Or, just enough to smear a snare transient. It can knock off a couple dB as the peaks aren't so additive anymore.

I'll get back to this stuff in a few days. Can't stop what I'm doing right now, (except of course to procrastinate on web forums!)
