[PD] Detuning reverb ?

[Pierre Massat]

Dear List,

I've been trying to recreate the effect that can be heard on Pavement's The
Hexx (http://www.youtube.com/watch?v=6N5tx68-d2I). It sounds like a
constantly downward detuning reverb, I have no idea if this is an existing
guitar effect or if it was created in studio by Nigel Godrich. My last
attempt resulted in this (
http://guitarextended.wordpress.com/2012/07/08/detuning-delay/), which
doesn't really sound like the original at all...

I think I need delay lines driven by a phasor with a squared output, so
that the speed at which the length of the delays increases is not constant.
I also think I need to envelop the delay lines somehow, and switch between
them so that the maximum length is never reached. But right now I short of
ideas. From what i've found on the web, this should be doable with a
granular delay, but I never used any granular stuff.

Any suggestion is welcome...

Cheers!

Pierre.
