I thought that may stretch the resources a bit. Glad to hear it’s being considered. With as much movement that can be put into Stix already NKS isn’t entirely necessary but would be a welcomed edition.NKS : Doable, but lots of work, so it will have to wait (though I've begun to think about how to do it it actually). Currently another Xils-Lab synth waits for NI NKS certification, and I've finished to translate one official add-on bank to NKS, in a way that should greatly enhance the concept of standard nks soundsets translations.
Perhaps a robust, persistent, midi learn may suffice, one where you can click on the graphic, turn your controller and have it mapped.
These are all just ideas, if you choose to implement any of these or the ones brought up by others I would be glad.
Stix has a solid foundation, let’s build.
