My band recently used the B.Beat for backing tracks, MIDI, and video projection for a show, and it worked well! Figured I'd share my experience with it. When I first got it, uploading the files to the B.Beat was very slow until I updated the firmware. Afterward, everything went smoothly and quickly. I found the app well designed, and I loved being able to easily select outputs, rearrange songs, and keep everything organized. I also appreciate being able to run a second one as a spare on stage. I did run into a problem with MIDI for lighting, so I reached out to the company for support. My show was in 2 days after I contacted them, and they solved the issue quickly. Stefano was incredibly helpful and kept me updated during the entire process. It was the best experience with technical support staff that I had ever experienced. I feel confident that if I ever run into an issue again, they will take care of it. They're proactive with improvements and new features, which is an added bonus. Overall, I like the B.Beat a lot for its capabilities and design. I don't know of any other company that's currently doing what M-Live is doing.
