Currently neither the tempo nor the signature is available to choose as binding target.
Both should be accessible the same way as when using “Metronome” as binding target.
Intention: I want to use transport triggers to realise tempo/signature changes (instead of having to create a dummy Midi file). It works (somehow) when I use Metronome as master, but this implies other adverse effects like not being able to freely set the transport position, etc.
