Written notes hidden by slash notation but audible in playback? (solved)

I’ve written a sample bass line in a jazz tune. For notation purposes, it has chord symbols and slashes. But my client also wants a recording to hear how it will sound.
Is there any way to maintain the audio of the written bass line behind a section that I’ve replaced with slashes and chord symbols?

I’m sorry. User error. I had accidentally erased the music under the chord symbols/slashes so of course I couldn’t hear any hidden notes! :unamused:

Yes, if you cover the bass line with a slash region, it will still play back!
