and is there any official statement about integrating soft take over into S1?

I put in a feature request 2 - 3 years ago and have not seen it yet.
It might be time for someone else to add an FR in the Studio One > Feature Request forum.

Not implementing soft-takeover in Studio One is an oximoron. One big reason why Studio One earned appretiation from new adopters was that the process of linking a hardware control to a software parameter was very quick an easy. Unfortunately, Presonus completely ignored the fact that the vast majority of MIDI controllers uses regular pots and non-motorized faders. Here is a list of controllers that use endless encoders:

● Behringer BCR2000 (discontinued): Not perfect but still the best endless encoder controller ever made.
● Behringer X-TOUCH MINI: Encoders require more than a full turn to go from 0 to 127. Encoders are detented (duh!).
● DJ Tech Tools MFT (development stopped): Not as fully feeatured as the BCR, looks pretty but still has some firmware bugs and it's not seen any updates foro years.
● Livid Code 2 (discontinued): Was the perfect MIDI controller—on paper—. In reality, encoder values would jump all over the place and not be able to follow fast encoder twisting. Returned mine after one day.
● Doepfer Pocket Dial (discontinued): and uses the Doepfer encoder protocol which is only supported by Doepfer and Studio One.
● Arturia Beatstep: Average encoders. Encoders are detented (duh!). Encoders don't have LED rings.
● Akai APC40 mk2: has 16 endless encoders, have not tried it personally so I can't comment. The only problem is that it has 9 regular faders which would also need soft-takeover.
● Mackie C4: Discontinued, encoders were too low-res, requiring too much turning to go from 0 to 127. Also, encoder caps were undersized.

Those are all the available options I can think of. As you can see, not so many, and most of them either inadequate or, worse, discontinued.

Also, there are too many endless encoder implementations, and there's never a guarantee that a given host can support a particular protocol e.g. Doepfer protocol.

Therefore: STUDIO ONE NEEDS SOFT TAKEOVER

With the Nektar LX49 if you turn Null on by pressing Shift + Null it allows for soft takeover

Bump.

There's certainly been other threads posted on this same topic that Studio One still lacks soft takeover for the majority of endless encoders by other manufacturers out there. I'm choosing this thread due to how long it's been, and that the OP saw fit to create an FR on the topic.
