sorry, I probably missed something cause I never could do that. ok, Synthonizer HAS tempo, so it works (i just tested now). but with a "Sculpt" Algo on my first H9, I just tried (with right footswitch) and it didn't work. When I long-click on the Right FS it just marks "unused" and if I then start tapping tempo nothing is received on the second H9, nothing changes…

what did I miss?

Hi, When I tap the right footswitch on my first H9 it marks "UNUSED" too, but the second H9 gets the clock and syncs with the tempo (showing ***BPM). Can you test again and pay attention to the slave H9?
