Thx! No sorry, currently there’s no raw material or templates (except the script) included. But the Kontakt resources are always open, so you can access and analyze any png files (like custom knobs, buttons etc) and maybe learn or utilize some techniques to build and design your own instruments.
You know, these tutorials are rather about the scripting not about the graphic design, so the instrument design is always very rudimental and nothing you wanna copy 🙂 But if you are missing some technical templates like for measuring and stuff, let me know.
