Hi all,
Hi Patrick,

yes, of course. I didn't use tremolos very often while playing around with
the new tablature appearance which yielded to scm/tablature.scm, so
I overlooked this.
1) Use

\override TabVoice.StemTremolo #'transparent = ##t
That's great, I'll provide a patch within the next days.

The #'beam-thickness of the tremolo beams is defined in
scm/define-grobs.scm as .48 * staff space.
In ly/engraver-init.ly we have the staff space spread to 1.5 * staff
space, so it would be optimal to
define the #'beam-thickness in TabStaff being 0.48/1.5=0.32 to ensure
the tremolo beams are equal
in size for normal and tab staves.

It seems that we should use 0.48 times the *actual* staff space, rather than
the default staff space.  That way, if someone overrides the space, the
tremolo bars will be the right size.
Sounds reasonable. I wasn't aware of the distinction between default and actual
staff space, to be honest.

I'll try to create a patch, give me some days and give me a ping if you don't hear from me within a week or so. I have ubuntu studio 8.04 on my machine (which I bought "as is" from a friend) with too little disk space for upgrading (he didn't use the standard installation defaults and cloned the image from a small netbook instead :-(, so I have to install 10.04 from scratch and hope to get this done within a couple of days.
