I am considering buying BIAB and am pretty sold on the syles. I do a blues solo: electric guitar, keyboard and harmonica. My question is, are there a number of variations within each syle. The Korg keyboard I had, which died, had 4 variation in each style, each one progressively more complex, syncopated, etc. Each style also had two fills, two intros and two endings. I was wondering if BIAB worked similarly within each style.
