Thank you, so that’s what I was doing wrong! I’m still new to Bitwig and to MPE, and I’ve only used it with the built-in Polymer synth, where I can just assign expression.
Nope, haven’t tried it. I don’t see the Linnstrument in supported models though.
Now I just have to figure out how to change the presets so that aftertouch and timbre are independent, as far as I understand the default settings are tailored to the Osmose, as mentioned by Roger here (for some reason I can’t create an account there).
