Hi Rory, it was my understanding given to me by Craig that the guitar lick ending was a pre-recorded (by him) WAV sequence created earlier in ProTools, then imported as a wav file into the T2 and triggered live via Multipad. I suspect whatever hiss heard at the very end may be an artifact of the recorded wav file, and not remotely as noticeable as heard after you amplified it thru heavy compression. No noise is detected (at least by me) in any other part of song, especially having the opportunity to possess the original uncompressed WAV file. - Scott
