Johnny Greenwood playing guitar through Max/MSP

Here's Johnny Greenwood from Radiohead playing 'Go To Sleep' on Jools Holland, with his guitar being processed though a Max/MSP patch (the full song is here). It inspired me to plug a guitar into the G2 and come up with this [600k mp3] effect, which stores the input in a loop until it's told to spit it out and start over, with an LFO changing the pitch of the loop. Anyway, here is an interview with Jonny where he talks about Max/MSP ("I love it all: I could fill pages with obsessive stuff about Max/MSP. I've even started lurking in chatrooms"). Sometimes, I worry that Jonny Greenwood is just a modern, high-tech, cool version of Michael Angelo Batio... (thanks, Aidan)
UPDATE: Here is my very scrappy Nord Modular G2 Patch.
