Bitwig Studio has customisable remote controls for devices and plugins which are rather like NKS mappings but with several advantages. For a start the editor for creating them is much more flexible than Komplete Kontrol's NKS editor as you can freely move around pages and also map the same param to multiple pages (eg if you want to create a Perform panel at the front). Also remote control mappings can be per preset or per device ('device panels'), and as you can use the Bitwig browser to browse presets for many plugin formats, including all u-he plugins and most CLAP format plugins (which have built-in preset discovery), this means not having to save potentially hundreds of patches as NKS. The system works equally well with Bitwig native devices (which are pre mapped) and plugins and supports any plugin format Bitwig supports, not just VST/VST3 but also CLAP.
If you also use the MOSS extension for Bitwig you get the additional benefit of not only being able to directly control params using the Keyboard knobs (something you can do with the built-in NI script) but also visualising them live on the keyboard display (which goes one better than NKS) and can swap between this and the mixer view. eg:
So with this in mind I setup an online repository for Bitwig Device panels along similar lines to the NKS User Library here, and got a thread going on the KvR forum to encourage other users to contribute - some have gone on to create dozens themselves and setup their own repositories to share them, so we have covered between us a lot of plugins by now (maybe as many as are NKS compatible?)
Instructions on how to import these into Bitwig are also in the KvR thread (post 1)
