So I recorded a midi track for Bass and it all worked fine. Playback was fine and it came out fine in my mix down. I then went back to the project, added a new midi track for drums and all I hear when playing back the song is the drums. No bass midi at all. Even when I solo the bass track there’s no sound, it’s like it’s gone. But I can see the Bass midi ‘notes’ on the screen. I just can’t hear it and it doesn’t go to my mix.
