I know you can start Pianoteq in server mode and send requests to switch pianos.

I am setting up a dedicated Raspberry Pi 5 to work with Pianoteq. I mostly use it headlessly, as I don't want to dive through menus every time I want to play piano. But I would like to select between a few instruments (a steinway, a rhodes, a wurlitzer). I'm thinking about building a selector (rotary encoder) that would run a script and allow me to switch between instruments with a physical action. Sort of recreating this functionality found in e.g. the Yamaha Reface CP (but with my own midi controller and speakers etc.):

My question is — does anyone know if it is possible to open Pianoteq into a specific instrument / preset / patch via a script (specifically within linux / pi os)? I'd like to have one script (shell script?) that opens into the Rhodes, one that opens into a Piano, etc.

Thanks
