Hi Chantelle and thanks for responding. I am using 2021 on Windows. I opened a song that uses the style _J410_BD.STY, "Evans Jazz Trio." Then I clicked on the Stylemaker button, and chose Edit Current Style. I see the Stylemaker window open, and I can click on Bass, for example, and see a bunch of cells, that mostly have 5's in them.

So I'm not working on a custom style at this point. I can't use Stylemaker on a style that includes RealTracks? Maybe this is just a fundamental misunderstanding on my part. If this is correct, does that mean that RealTracks have their own, pre-recorded patterns that can't be altered? I was under the (possibly wildly optimistic) apprehension that even RealTracks could be "re-styled."

How do I identify styles that I can use in Stylemaker?
