Looping without Warp, with pitch change

[TrierMusic]

Howdy all

I have sort of a weird question here - how can I seamlessly loop a clip (in Session view) that is not warped and shouldn't be quantized?

To be more specific - I want to have a mangled drum track for an experimental improv piece. I want to play an audio file of a long drum solo but be able to change the pitch, and as the pitch changes change the speed as well (thus, no warp).

This all works great until it's time for the clip to loop - then there's a pause until Live's metronome gets back around to the beginning of the next measure.

I guess I could set the metronome to a ridiculously high tempo? Any other solutions?
