Any way to load a .carxp file through OSC command ? #1036

Hey ! I'm creating an open-source drum module, and I wanted to know if it was possible, through OSC commands, to load Carla project ?

The final result is to change VST drum kits when clicking a button in my GUI (an electron app). I see there is a command to change a parameter in the VST, but I don't know the available parameters in Steven Slate Drums VST :/

Thanks !

This is not possible at the moment. OSC usually means remote control, so I want to add something to allow listing possible projects before I add the possibility of loading them.

Any possibility to know which parameters are available in a vst?

guillaume-gagnaire commented 4 years ago

I think I have found them, it's base64 encoded in the .carxp file ?

Ok I was confused between engine parameters and VST-related parameters, there is a way to change internal parameters of a VST ?

falkTX commented 4 years ago

what do you mean by internal parameters?

the host can only change what the plugin exposes. in vst, it is a list of 0.0-1.0 normalized valued parameters. trying to automate vst plugins is not pretty... :/

but carla osc parameter changes use the index of the parameter, so you only need to find out the right one. then the value goes from 0 to 1 as a float (for vst plugins)

Need the same feature here. Anything new since the original post 4 years ago? Thanks
