Thanks for the report. I have found the issue with the variable action. Adding the time reference to the title action is reasonable; I’ll take a look at it.
For context on the {title:} request — I run a Stream Deck + on a live keyboard rig, and I’d love a dial whose title shows Ableton’s live BPM in real time, so I can confirm the tempo at a glance on stage. The @bpm variable is the other half: I want several keys/scripts to react to that value (e.g. a visual cue when the tempo changes between songs).
So both would be gold: the {@variable} fix you already found, and — if it’s reasonable — extending (time) to the {title:} action for dials and keys. Happy to beta-test any build whenever it suits you. Cheers!
