Thanks for looking into this. It sounds like I am limited by the double-time in that particular style. I guess I will have to use this style without the bass, and use my accordion to provide the bass during performance. Will I have to look for bass tracks without the double-time, or is there should I look for a different style? Since I am rather new, is there a way that PG can change or improve the functionality of the software for issues like mine? For reference, I am using BIAB 2018 build 510. By the way, the accordion track sounded just awful at playback, which is why I muted. Is this because I am trying to play a 2/4 polka? Most polkas are not written in 4/4 time. My arranger midi modules do a much better job generating accordion accompaniment than this style. I know I have a lot to learn, so I will be patient. Thanks again for all the help, everyone.
