I have a musescore and it fits in the DAW at the same time signature.
realband will import it and give the 6 chords on the bar, if the BiabVST could be made to support these time signatures it would solve the issue rather than having to redo all the Biab programming. The BiabVST is working in DAWs so it need to comply with their time signatures and tempo maps to add any new tracks to their projects.
