Aaah, I see now. OK. Well, this really intrigued me and just until now I’ve been trying to assign, say Osc3 Mix to CC80 for example and it doesn’t work. So this is basically in the MIDI realm, and Podium is unfortunately lacking in this department. Initially I thought it could be done through the Parameter Properties dialog of the CC and assign it to a plugin param, but the box is grayed out, then tried drag-and drop directly onto the desired automation lane but didn’t work either, so…internally it doesn’t seem to be possible, or I am overlooking something.
On the other hand if your plugin has a MIDI Learn feature it is possible. Just tried it with Oatmeal and DuneCM and was able to assign Cutoff to CC119 without any problems.
Or alternatively you could try a virtual MIDI cable + some midi plugins that can assign MIDI CC to a plugin parameter (there must be some).
This reminds me of an old request of mine about Global Learn feature in Podium.
