Really? š Then I didn’t check it properly the first time around.
When the fader is set post-effects, the automate parameter submenu in the track context menu will always show parameters of the first effect track, no matter on which effect it actually is. That’s why I suggested additional submenus.
When it’s set pre-effects, and only then, you get parameters of the source track (I’m talking about tracks without source or input mappings, it always worked fine with those). If you didn’t know about it, it might even be a good-natured bug. š
This answers my original question. However, if you enable pre-effects level automation first, switch the fader to post-effects, and then try to also enable level automation on the first effect track (or from the track context menu as usual), Podium thinks its the exact same parameter again and the pre-effects level parameter turns red… It works if you create post-effects level automation first.
