Notes in parentheses, horizontal brackets, midi from TabStaff

[Michal Vopalensky]

Hi everybody,

I have two simple questions on the notation. Hope somebody can help me...

1/ Is it possible to place some noteheads into the parentheses? 

2/ Anybody knows how to generate an angle bracket (^) upon two notes (or stems 
of these notes actually), splended from the first one to the second? There is 
described how to make square brackets of this kind in the part of the manual 
dedicated to the educational use. But I would need the angle brackets instead.

Third question is that when I compile a source for tablature, there is empty 
midi output. When I just change the TabStaff to Staff, there is normal midi 
output again, but of course I don't have the tablature as a printed result. 
This is not a big problem, but maybe it'd be a bug (?).

Thank you all in advance,

Michal
