Sibelius 6 is a giant leap forward in notation software – with amazing new features and improvements for educators, students, composers, arrangers, copyists and musicians of all kinds.

Fixes and improvements in Sibelius 6.0.1

* Sibelius’s memory usage no longer grows unbounded when scrolling the
pages of a large score without editing (e.g. during
playback).
* Sibelius no longer crashes when pasting material at the start of a score
where the first item in the top staff of the selection would need to be pasted
before the start of the first bar.
* Creating a key signature in a dynamic part no longer causes Sibelius to
crash.
* The initial volume used by Sibelius when clicking on a note in the score, or
inputting a note via the Keyboard or Fretboard windows, before the score
has been played back is now correct.
* The Allow first syllable to overhang barline option in House Style > Note
Spacing Rule now works as expected once more.
* Lyric hyphens are now correctly centered between syllables, as they were in
Sibelius 5 and earlier versions.
* It was possible for Mixer redraws to cause a crash under some obscure
circumstances. This bug has now been fixed.
* A minor problem with the Essentials Choral Combo sound set (for users of
Sibelius Sounds Choral for Sibelius 6) has been corrected.
* Plug-ins > Simplify Notation > Combine Tied Notes and Rests now runs
without an error.
* Non-magnetic lines no longer perform the look-ahead associated with the
new slur direction rule for magnetic slurs, resulting in a small performance
increase in scores with many lines.
* Various small problems related to the appearance and positioning of lines
that cross system or page breaks when exporting scores to Sibelius 5 format
or earlier have been fixed.
* A number of small improvements to the order in which scores are compared
when exporting Rich Text Format log exported via the Export Log dialog,
which now also includes line breaks.
