Thanks for the replies and having done some further research based on your answers I think that I've made a bit of a mistake.! I bought the basic pro pak.

Basically I just wanted to have an acoustic trad Irish band of upright bass, rhythm guitar, bodhran and maybe a mandolin or fiddle for variation.

I need to do Jigs, slip jigs, reels, slides, hornpipes and polkas.

It seems not possible to do most of this in the basic version, in fact pretty much none of it! There's the odd reel but based around a piano (huh?), with no alternatives.

I thought there might be 1 or 2 packs extra to do this but I see that I would need to buy at least 6 just to get going and even then it would be limiting, not to mention expensive!

It's just such a pain to record backing tracks myself in the real world and I thought this might be a quick way to bypass that workload. Besides which, my bodhran playing is nearly as bad as my fiddle playing.
