Sorry if I was not clear enough.
I was looking for a method to circumvent the midi-error, but keep the
visual output.
Let me be a bit more verbose:
The following gives nice visual output, though triggers an error with midi:
{ c'1\> c' c'\! }
Inserting an expicit Dynamic resolves the midi-error, though, the
Hairpin starts at the right of the DynamicText, ofcourse.
{ c'1\mf\> c' c'\! }
Trying to remove the printed DynamicText via \hide or \omit or
#point-stencil, leaves the Hairpin untouched, i.e. starting to the
right of the now invisible or non-existent DynamicText-stencil.
(Little different with \hide)
{ c'1-\hide\mf\> c' c'\! }
{ c'1-\omit\mf\> c' c'\! }
{ c'1-\tweak #'stencil #point-stencil \mf\> c' c'\! }
The only way I've found to get back the output without the explicit
DynamicText was to set Hairpins left-bound to DynamicText-parent (and
setting DynamicText.stencil #f ofcourse).
{
c'1\mf -\tweak #'after-line-breaking
#(lambda (grob)
(let ((dyn-txt (ly:spanner-bound grob LEFT)))
(ly:grob-set-property! dyn-txt 'stencil #f)
(ly:spanner-set-bound! grob LEFT
(ly:grob-parent dyn-txt X))))
\>
c' c'\!
}
Cheers,
Harm
