Sadly its not working for me at all and weirdly I seem to have the opposite problem somehow 
Im using 2 6000s and a Xone 96 and want to sync some external pedal type effects units (Eventide H9 and Strymon Nightsky, which I both really would recommend by the way) via Ableton Link and MIDI
It should work like this: SC6000 Tempo –> Ableton Tempo → MIDI over USB → Pedals…
But somehow Ableton is always the “master” (from which I understand there shouldn’t be one in Ableton link) regardless of which link is started first etc. Pressing master buttons on the players doesn’t change a thing… Any advice?
