Radium

Thank you for your answers.
So, is it possible to do Time stretch with the 09xx parameter on the Renoise sampler in Radium sampler, as in this video (https://youtu.be/VAnTpsUMDMg)?
If possible, what parameter should I use?

Hi, how i make stretch loops in bpm? is it possible? What commands i should use?
I want it to stretch automatically when the bpm changes.
Thanks...
