BiaB does an excellent job of making a backing track from a chord progression. Getting a good chord progression can sometimes be a bit of a problem as, whilst they're often online, not all are authentic. The official sheet music may or not have the chords stated ... often not.

BiaB has a tool, Auto Chord Wizard (ACW) that will try to extract chords from a recording.

Once you have a chord progression in BiaB, try out different styles with them, to find a backing that works for you. Find a sound and feel that suits you, probably regenerate a few times, freezing tracks as you like them.

This almost certainly won't make a backing track that's the same as the original song's, but it can make an excellent backing track for a cover.

There's a "Melody track" that BiaB won't change, so you could import MIDI or XML into it, it can be a single-line melody or a full piano piece. It, indeed any track, can be muted completely or by bars or by choruses/verses.

There's no demo version, but I believe PGMusic are as good as their word on the 30 days unconditional money back guarantee, though I suspect they're not that often asked to do so.

The bad news is that the "Pro" version is the entry version and has very a limited selection of styles. Just about everyone advises getting the best/biggest version you're prepared to afford. Most of us have the UltraPAK. You may find that it's cheaper to buy the Pro version and then upgrade than to buy a bigger pack at the start.

PGMusic's videos are good but can be a bit overwhelming and hard to navigate. I rather like the versions done on YouTube by Henry Clarke.

There are differences between the Windows and Mac versions, the Mac vewrsion tending to be somewhat behind.
