I can recommend the 2016 version of Band In A Box, having purchased just about every version since its inception. I’m on the Windows side. If arrangers could only duplicate all those styles, or if BIAB could only get that fat, full sound like arrangers do! I go back and forth between the two, depending on the gig, or recording situation. To my hearing and preference, BIAB styles are more realistic and natural sounding, due to their Real Styles (real players). On the other hand, arrangers in a recording situation, have a much bigger, fuller sound on playback. Guess it depends on what one prefers. If you’re not familiar with BIAB, how about several thousand styles to select from? There’s something for everyone there.
