I am new to Band in a Box. I've listened to several videos for beginners, but I'm having trouble setting up the form for my first song (basically a simple 12-bar blues song). When I clicked on Song Form and selected to generate an intro, I indicated I wanted a four bar intro, it generated an automatic intro; however, I expected to see a repeat mark at bar five and I am not seeing a repeat mark. I basically want to create a 12 bar blues song with a four bar intro. I want it to play five choruses, and then I want to write out the rest of the song, which is 20 bars after 5 choruses are played. I tried to select a Song Form and fill in the information for each of the sections but when I selected Generate Form, I got a message that says "there is no form string (e.g. AABAC) or no valid sections defined. Unable to generate a song form." Also, for the tag that I'm trying to create, I was hoping to enter one chord per 8th note in one bar at the very end, but it seems as though I can only enter one chord per quarter note. Is that the case? Can anyone refer me to a video or videos that will address these issues that I'm having?
