The synch issue is bad enough, but ultimately fixable on the back end. My biggest issue with this app is that I keep losing the entire recording. For no reason. I can check it throughout the event and ensure it’s running, but after you finish recording, if it’s a video of any substantial length (longer than maybe 15 minutes) it will get stuck, apparently, while processing the video, and not finish it. And then I lose the entire recording! Plenty of space left on the tablet (a 2018, up-to-date iPad), and functional for short videos, yet with no warning it will take forever to process and then just give a quick error message and... bye bye. Using this with the (low quality, overpriced) GoMixerPro, also from Roland, I’ve now lost 1 band rehearsal and 1 live performance! I’m at a loss for any explanation. The videos are simply gone, and not coming back. Could’ve used the basic (stock) camera app on the tablet, and will going forward, because this app is getting deleted and doesn’t even deserve 1 star. Thanks Roland! I always liked the company but recently they’ve put out some alarmingly low quality products with their name attached and it’s tough to know which ones might be decent ‘Roland’ and which ones don’t deserve to be under the same banner.
