Just a few to look at…..ARe you using Logic, Protools?

Mach Five 2
Radius ( for Logic ) made by izotope’

Its all good… I use logic and if reason lets you use a vst in the mixer enviornment you can get other software to use. Normally reason has its own instruments, but check to see if reason can rewire or use other VST instruments… if so you can find some apps for time stretching… check with reason for dealing with audio, they may be some functions that can do what you need…

my fav method is pretty gritty…
i use Renoise, and trigger the sample on every tick of the pattern then use the sample offset effect (09xx) and interpolate the change between the 2 points in the sample i want to stretch from… this can be done pretty much the same way in modplug tracker which is free… may seem a little weird but it works really well and can let you execute some really different sounding stretches
