I'm using the Roland Cube Street because it serves as a music stand for my iPad Pro 12.9". The Bose have a bit more low end, but the Roland has 3 band EQ and more effects available ..... plus 4 channels - 2 of them stereo. My iPad is loaded with tracks, MP3, midi files form all over, but largely, I use Karafun, a subscription service. I started using it a lot when I got the job at THIS restaurant ... there were so many guests that loved to sit in, and sing, but didn't know lyrics that I just pulled up Karafun, and left it there all night. A little lazy, but the end result was a seamless show that most enjoyed. I'm gonna miss this place.
