I just ordered and received a bunch of individual songs during the recent sale. Turns out I cannot figure out how to put them on my BB. I assumed these songs would be play-along, meaning I would play the complete song’s guitar parts along with the BB participating as the drummer. This was the implication in the sales offer which showed beats/minute and so on. Also, my BB unit does not have any electronic ports to hook to nor does it have an SD card. Am I out of luck? There was no discussion in the sale telling me older units are incompatible. Very frustrated, I wonder if there is a solution other than obtaining a newer unit. thanks
