Hi Vincente, thanks for the suggestion. However, I do not only want 
to delete a music expression (which can be tagged), but an entire 
staff, namely the tabStaff. I wouldn't know how to create code 
removing a staff by tagging it.

Dmytro's suggestion looks more promising, though I haven't been able 
to generate code that does the job so far. When I code

==================
\new Devnull
<<
        \TablatureNotes
>>
==================

I still get an empty tabStaff and two tabstaffs below it for both 
voices in the \TablatureNotes. Replacing "Devnull" by "TabStaff", I 
get one tabstaff with both voices combined. I guess Devnull is not a 
manner to suppress printing the staff.


Thanks anyway,
Marten
