Okay. Give this a try. Here are steps and some screen shots to do the 4 chorus example you gave. Let us know how it goes.

01. Create a complete 32 bar, 4 chorus song. Example will use _BULB.STY and no Utility Tracks.

02. Drag the Master Icon into the WAV quadrant of the Drag/Drop icon and render.

03. Select the DAW Mode Button and drag the WAV render onto your desktop.

04. Close DAW Mode.

05. At the top of the Chord Sheet, select Audio\import audio.

06. Import the saved WAV audio file from your desktop onto the Audio Track at the default settings. This should import the render synced with the BIAB instruments.

07. Open Bar Settings (F5)

08. Select Chorus 1

09. Mute All Tracks at Bar 1a - Set the Audio Track Back to normal.
Set All Tracks Back to Normal at bar 9b - Set the Audio Track to Mute.

10. Select Chorus 2

11. Mute All Tracks at Bar 1a - Set the Audio Track Back to normal.
Set All Tracks Back to Normal at bar 9b - Set the Audio Track to Mute.

12. Select Chorus 4 (skip chorus 3 because bars 1-8 are not saved).

13. Mute All Tracks at Bar 1a - Set the Audio Track Back to normal.
Set All Tracks Back to Normal at bar 9b - Set the Audio Track to Mute.

14. Close Bar Settings (F5)

Press play to hear the song. Observing the BIAB Mixer, the Audio Track vue meter should play bars 1-8 and the other instruments are silent. The Mixer instruments should transition to playing at bar 9 with the Audio Track Silent. This will repeat for Chorus 2 and 4 while Chorus 3 plays through normally.

Bars 1-8 for Choruses 1,2, and 4 are audio synced to play with the Chord Sheet and will be saved with the file. Editing to the Chord Sheet can continue without affecting this file. The file will change if the Key Signature or tempo are changed without altering the audio wav. Save the file to preserve edits.
