i'm not aware of a way at this moment in time. When i wanted to do this in the past i just deleted the two split-mono tracks then re-imported the stereo file.
Would you know that if you added so a couple of tracks from a midi file to a song, would it play them back from a sequencer via a midi out cable from the b-beat.?
@@kevanbarrett7411 as far as i know, whatever midifile you add to the b-beat it will playback. You'd have to chose and set your midi-tracks (meaning instruments/midi-channels) in your midi software then save that midifile as you wished it to be played on the b-beat. There is no option to control any midi functions/data on the b-beat at the time of writing this.
