Hi Wendy. I recreated your chord progression to duplicate your issue and as luck would have it, instead of Horrid and Jerky, smooth and silky showed up to play in my SGU file... But I think I can address your issue and suggest an easier solution that does not involve having to open a separate BIAB chord chart or migrating earlier than necessary to Realband or another DAW.

<<< Is there a way of telling all instruments except Bass just to 'play through'on those two cords if thats what it's called. >>>

Try this.

Renerations attempt to slightly change playing over the chord chart each time. Therefore, don't initially put the two bars using the slash chords. Generate the two bars with just the G chord. Freeze all the tracks except the Bass Track. Insert the two bars of slash chords and regenerate the Bass Track. This method should eliminate the BIAB search engine from searching for slash phrased audio in the RealTracks of all the instruments except for the Bass RealTrack. You also don't have to necessarily put the G chord in both Bars. BIAB selects audio in varying lengths of audio clips up to 8 bars I think. This means if you place 4 -G- chords in the two bars or only one -G- on the first bar and leave the other bar blank, BIAB will search out different RealTrack audio clips.

It is my understanding that if your chart reads G,F,C; the next time that progression comes up in the chord chart, rather than repeat the same audio, BIAB searches and selects a different audio clip from the RealTrack to give the song more of a feel a 'live' musician is playing the track. Renerating always provides a slightly different render.

Starting the chord sequence in the order I suggested above, BIAB never looks at the 'slash chords' audio clips for any of your song's instruments. Freezing the tracks after generation of Normal chords and then inserting the Slash Chords and only generating the Bass Track isolates the Slash Chords audio clips to solely the Bass Instrument Track. This method should give you the same result as you'd get using a second session of BIAB SGU file.

Hope this helps save you some time and effort without the trouble of making additional SGU files or exporting to a DAW earlier than necessary.
