RC-505: Variable Speed Without Time Stretching?

Hello, I'm thinking of getting a RC-505 as a rudimentary recorder for a few different sequencers/synths. I understand the RC-505 does a bit of time stretching when you change the tempo of already recorded tracks. Is there a way to disable this and have it pitch them up or down unstretched instead? I couldn't find a clear answer in the manual or otherwise and not having proper variable speed playback would be be a deal breaker for me.

If it can't do this, can anyone recommend an at least 4 track looper that can do this?
