Hi, ProTracks came free, I think with an M-Audio midi interface. This was a few years ago. It's a recording software that included Cakewalk. (I couldn't find an active link) I used to know what I was doing on Cakewalk a long time ago. That was a few computers ago.

I remember I preferred Power Tracks to Cakewalk at the time and Power tracks was free. When I upgraded BiaB a little while ago the Rep said I should look at Real Band if I was interested in Power Tracks.
