Countryjoe - Chill!! Folks are only trying to help best way they know.
IM A NEWBIE too and id be dead in the water if it wasnt for these guys.
AFAIC BB is where you search fir a Style or make one up, put in yr chords to try things,arrange etc. ON THE FLY means that a minute you press the button it will play what you have. Not have to wait. Beware. There are TWO buttons. One replays what you had, the other REGENS it and plays the new form unless you FREEZE a track. (,i just discovered that;-))
RB is like PGs DAW. You can do everything BB can do it just takes longer IMO. But you can manipulate bits of tracks etc, add lots more tracks etc. Itsca bit beyond me at moment but I'll get there.
BTW Noel those links are v helpful. Thanks.
