Thanks again MarioD,

Yes, I see I can drag the master, but that gives a mix, which I almost never want, since the whole purpose is to remix in Studio One. What I like is each track separate, but preferably in one batch drag and drop. I think I will use your method when I want one or two tracks, or when I add an additional real track player to an existing song, or update a track which I re-rendered. But when I want a whole song with separate tracks the best method seems to be the wav button in the upper right, and keep the destination folder always open on the desktop. That is pretty much the same as using the DAW function in the upper left. From that folder you can grab all the tracks and in one drag they go into separate tracks in Studio One, which I just tried. I realize now that using a dedicated folder, specified in BIAB preferences, is better if you often update tracks and make improvements because you can control the deletion of tracks no longer needed, which saves space on my file system. I also just set up a batch renamer protocol in my file renamer program so that I don't get the long filenames in the Studio One tracks.
