I am on BIAB 2020 (build 324) and MacOS 10.14.6, but I get the same error in BIAB 2019. When I save a midi file to disk, BIAB states an error message "no drum style is loaded, cannot pick for bar #xxx". The bar number varies with different songs, but is generally outside the region of the actual song. If I play the song first, the error message does not appear. Why is this happening and how can I fix it ?
thanks, Martin Klein
