So this is an issue I've touched on many times before, and it has yet to be addressed, so this is just an example of an issue that crops up 90 percent of the time.

Now personally, I use BiaB mainly for insrturctional purposes. I play guitar and bass, and only read Tablature.

This is a screenshot from one of the Vocal ooh aah tracks. The bass is RT #701. As you can see, the tab is missing from an entire bar!

What gives folks? I really love this program and want it to work for the purposes I shell out good money every year for.

Please address this, PG!

I had a look at your issue.

As far I can investigate, I have narrowed the issue to the following :
1) tones involved: Ab, A, Bb.
2) tested chords : Ab7, Ab2, Absus - A7, A2, Asus - Bb7, Bb2, Bbsus.
These chords may have or not the Tab displayed on the the notation sheet.
When you regenerate the song , you may get the tab for the Ab7 but nor for the Bb7. The next regenerate time, you may get the Tab for the Bb7 but not for the A7 and so on.
Other chord types may be involved.

I report your issue to the developpers.
