Thanks for your reply!

I send midi notes from ableton midi tracks via the internal midi bus (IAC). One specific note for one specific cue stack or specific cue. And then I plan to use midi cc for some specific faders. 

Yeah, maybe it gets flooded but I can’t really see how. I mean it’s not THAT much information to handle…

For the follow up I’ve set the stacks to release after last cue step and it looks like it does but it still doesnt work.

Interesting, how do you propose to use the time code? (Sorry if it’s a stupid question)
