I´m not the OP
, just got concerned that the Resolume Link implementation may have trouble when changing tempo. That would have broken my setup, which is: Link syncing Traktor, Live and Bitwig.
Now that I re-read the entry post (the third time ^^), it seems OP only faces an issue of concurrent time masters between "Link" and "Tempo Follow". Sorry for misreading that.
Please forget my earlier post, I´ll happily go forward and integrate Arena into the existing setup.
