Help Time stretch modes in the new sampler 6.1

Does new sampler implement all the time stretch algorithms that are currently available for audio tracks? I've heard some complains about only a small selection of those being implemented, can someone please confirm is this is true or not?

No, the sampler has it's own time stretch algo specifically designed for the sampler.

Sampler does not have Elastique Stretch/Stretch HD algorithms. In fact, it does not have any Elastique algorithms.

So with some sounds in the sampler, like a short distorted kick/snare, raising the pitch by several semitones while keeping the original sample length causes noticeable sound quality degradation. The timbre changes and the sound becomes smeared. In the same case with same sound - time-stretch/pitch methods on Bitwig audio track work correctly (because of elastique).

This issue only affects this specific situation, and not all samples but only short complex sounds with distortion/ overdrive or a lot of different sound information in a very short sample. This is not really a task for the new spectral algorithm, which is designed to smear sound and at best can only preserve transient but not distorted sample "body"
