I did read.
It is not designed to orchestrate multiple instruments so that they play together in lock-step along a shared timeline.
Ableton Link is the absolute master. It accepts tempo changes a relays them. When you move the the pitch fader on your deck (when Link enabled) are you actually controlling the pitch on your deck?
Maybe your pitch fader tells Abelton Link (if you’re master/lead/peer/etc…) first so that Abelton Link can relay changes to everything at the same time including your deck. You can achieve the illusion of real-time sync only if things run in parallel to a master. Anything serial can never sync unless you offset the master.
Who knows, maybe I’m just telling a good story.
