They recently (in the last month) added Beat Sync to the P6, Pro 2, Rev 2.
I own the P6 as well as the P12, and the update really opened up the P6 for me (THANK YOU SEQUENTIAL/DSI!), so I'm really anticipating a similar update for the P12.
I just wondered if anyone had heard anything about the P12 on social media or anything. I thought I read a thread about Beat Sync on the Pro 2 that said something like "they said it's coming for the others..." but I may have imagined it, because I can't find it again.
