Hi @yaxu, I'm using Carabiner to link with Ableton link a lot at the moment and it works fine for me. Indeed, if you change tempo's, it goes out of beat, but if you change the latency correction on the end of the line a bit up and down, it aligns very well again with Ableton link (feels a bit like with dj-ing, you shuffle the pitch of the second record player a bit forward and backward to align the beat with the record playing). I used that procedure in this performance ,a couple of times, two weeks ago : AI & Music S+T+ARTS Festival - Bot Bop - Integers & Strings - YouTube
The stringquartet gets there score generated on the spot, linked to Ableton Link, so it's very important for his project that Tidal is in sync with the rest of the band, and the beat is correct, and it works out pretty well, with a little workaround...Would be better of course, if we didn't have to do that . .
