Hey guys. Okay, I purchased a new 6 core MacBook Pro a few weeks ago to help video processing with my Rekordbox & RZX setup. After installing Rekordbox and driver on the new MacBook Pro I reinstated my Collection etc. from the external SSD where my Master Database is kept and started a rehearsal session. About an hour into the mix the master output of the RZX just stopped - the channel strips had audio flowing, but the master channel meters and output were gone. I shut down and rebooted everything and all was fine again. As a precaution I reinstalled Rekordbox and driver anyway. After a couple of weeks of rehearsals the problem had not reoccurred, so I went ahead with a show (infront of several hundred people) last Saturday. I’d been outputting Rekordbox video for a few hours without issue prior to my DJ set, however when I started the music I turned up the master output knob on the RZX, and guess what? Nothing! Same as before, the channel strips were hot, but the master output was completely cold. I had no choice but shut everything down and reboot to get things running again - not very cool with an expectant dance floor at 3AM! I have the RZX connected to the MacBook Pro with the official apple Thunderbolt 3 to USB adapter, and the setup worked perfectly (bar glitchy video) with my previous MacBook Pro. Can anyone please help resolve this issue before my next show in a few weeks time?!! Many thanks in advance. Cheers
