I have never been able to make proper use of the repeats and chorus functions in BIAB to get a correct playback of a traditional polka. Most of the polkas and waltzes I play have a two to 4 bar intro, followed by an "A" section that repeats, a short "B" section that ends in a D.S. back to the beginning of the "A" section. At the second ending of the third time through the "A" section, you jump to a trio in a new key. The trio "A" section is then repeated twice, followed by a "break strain" with a Da Capo or D.S. back to the beginning of the trio to finish the song.

This form is most like a traditional march. I do not understand how to make BIAB follow this form, since the software seems to lend itself more to song forms with verses and choruses. Can anyone give me some advice?
