I am new to band in the box and am having trouble ending the 12 bar blues. I would like to end the chorus with a I, V every time I am going to repeat the chorus. However the last time I play the chorus I want it to end on a I,I. I thought the tag function would do this so I put a tag at 10 and a coda at 13 and 14. Band in the box does not seem to terminate the song at 14 though. It mysteriously likes to add bars after 14. Why is this so hard?
