The Elastique algorithms aren’t up to date anymore.
Besides that Cubase is still missing a slice-based stretching mode. This has nothing to do with Slice at Hit Points where you have to do all the work by yourself (overlapping and gaps!). Bitwig, Logic or Live do have slice-based algorithms which sound amazing for drums and all transient intense material as only little parts (slices and not the whole audio file as it’s the case with Elastique) are stretched - no overlapping occur and gaps are filled up based on different principals (granular, forward, backwards and so on). In other words there should be a mode for drums where you just have to select an algorithm without fumbling your hands off in the sample editor for a simple tambourine loop.
For overall pitch shifting and time stretching there is also the Serato Pitch 'n Time algorithm which is foolproof for “whole tracks” and also licensable. It is available as third party expansion for Logic as well as Pro Tools: https://serato.com/pitchntime
Quality wise this would be my first choice.
Then there is the already in WaveLab integrated Zynaptiq ZTX algorithm. Also available in Digital Performer. However WaveLab isn’t capable of stretching the simplest loops as bass lines or drum loops, sounds like sh’’ despite the fact that ZTX was praised for “the” best out there: http://www.zynaptiq.com/ztx/ztx-features-and-specifications/
Listen to it here: https://www.admiralbumblebee.com/music/2019/01/06/ZTX-vs-Elastique.html (anyway, I don’t think ZTX is better than Elastique in these examples, it depends purely on the source).
When ARA2 will be better integrated in Cubase it will be possible to use the stretching algorithms (three of them) of Melodyne (cp. Studio One, Waveform), however even Melodyne can’t beat Logic or Live in terms of (nearly) artefact free stretching of transient based audio material.
Steinberg should just overhaul the stretching capabilities, especially in regard to a slice based stretching mode.
