I use uTrack24 as the main backingtrack machine. I am very satisfied with hardware.
However, it is almost impossible to use uRemote for on stage control. The user interface is not ideal for live use. The playlist is too small at the expense of other controls. I would welcome simple software – only a playlist with a quick choice of playlist/song selection. Alternatively, play/stop button. But I use footswitch on stage for that. The software should have both horizontal and vertical variants. Please program something simple, I’m a garfical designer and I can make a free GUI if you need :-))
