Biab MultiRiffs an Easier Way You can do it this way until PG do something about it:
Generate and solo the first section in track 1 to your liking then mute it with F5 where the good ends and Freeze the track.
Solo Track 2 (and Audio) Un-mute F5 at that bar, Generate the next section to your liking then mute it with F5 where the good ends and Freeze the track.
Solo Track 3 (and Audio) Un-mute F5 at that bar, Generate the next section to your liking then mute it with F5 where the good ends and Freeze the track.
Solo Track 4 (and Audio) Un-mute F5 at that bar......
Now mute the Audio Track and Drag Render the master to get your RealTrack.
