Just for the record I am not stating that any sequencer can do what band in the box does with MIDI.
Cubase (my pref sequencer) can cut up and rearrange a MIDI performance (on a MIDI instrument) then rearrange it, note by note, bar by bar, section by section. It can change its key, move notes, show them in notation - print the notation individually or in gruops, repeat bars,lengthen notes, shorten them, assign them to different VST instruments, change the clef, it can change a single note to a [particular articulation (e.g. marcato strings), it can apply swing or other quantize, or effects to MIDI - either MIDI fx or Audio, it can convert a monophonic Audio performance to MIDi (a la melodyne) and back and a lot more besides - but it is NOT BIAB.

It cannot give you a fully fledged performance in high and authetic quality as BAIB does - in minutes. Nor does it have a library of songs at the push of a button. BIAB is excellent at this.
