I saw your question last night, but I didn't really understand what you where getting at so I didn't respond. Unfortunately I'm still not sure I understand what your going for.
If you've got a 1 bar guitar hit, and you want it to spread over 4 bars, but by stretching it without changing the tone and without cascading it with overlapping multi hits, you would want to reduce the BPM.
When using Timestretch in the 500, you set a bpm for the original sound that you want to stretch ( it doesn't matter what the value is, its only relative to the stretched result), then you choose the target BPM.
So if you set you original bpm at 130, and your target at 65 it will stretch the sample twice as long (or something like that, it'll be longer).
But stretching a sample too far can distort it. So you'd have to experiment to see how far you can stretch it without mangling the sound. And you also have to experiment with the various preset algorithms to get the best result.
Time stretching on the 500 can be kind of shooting in the dark as far as results, you just have to fool around with it for awhile.
But if I'm understanding what your trying to do, It sounds to me like you'd be better off overlapping multi-hits and maybe putting some echo on it to make it sound like a constant tone.
You could even resample that layered noise as a new sample to free up your effects again.
