I'm spending most of my time, now, with Band In A Box, rather than my S900, since it has many more styles available. I'm a guitarist who gigs solo several times weekly and needs plentiful backing tracks across a wide variety of styles. Like the original post suggests concerning styles, I've found too little of what I need on arrangers, or too much of what I don't need or will use. Plus, a laptop is easier to transport than a keyboard. At present, BIAB seems to be a better choice. What would be great if one of the major arranger manufacturers could collaborate or buy-in with BIAB to have its styles tweaked for arranger play and available for purchase. Don't imagine that will happen soon, if ever.
