i was doing a playback show that required no audio problems, so I decided two MacBooks with QLab and a dual box so ever6 cue would fire off both macs and if anything happened, a hot changeover saves the day. Audio via usb out to the X32. If used this dozens of times for recordings so I know it works fine. One run through. A dance show with lots of kids, but no time for a proper dress rehearsal so during the run through, done in stops and starts, and digital distortion starts to creep in. Not bad at first but getting worse during the playback. Pull out usb, re plug. Next song starts fine then starts to gradually sound worse and worse, so swap to the other Mac which on the analogue out is fine. During a break, I swap them. The usb connection does the same thing. This points to the x32 not the macs. Ran analogue for the show and it was fine, but what happened to the digital connection. Recording has always been fine, but playback not good. I’ll try it on another mixer today if I get the chance but is this a known issue?
