 transients. I like Rubber Band as an effect, so I'm fine with
 transients, but for your needs they might be a problem.

 Found a new one Zita-resampler. Can't wait to try it.

 So far I'm only using SRC, currently writing classes for the others.
 So far so good if I don't push it with waay too many audio tracks.
