Bugfix Mozart 15

Improvement history for Mozart 15


Mozart Service Pack Infelicities addressed

Mozart 15 version 15.0.3

13 January 2021

  • With thanks to Richard Mills: Horizontal offset of bar numbers at the left of the stave, where there is a key or time change. This also fixes misplacement of rehearsal marks and text items at the start of a stave where there is a key or time change.
  • With thanks to Bengt Johnsson: Muting notes now also silences accented notes.
  • With thanks to Barry Brookes: Mozart was sometimes crashing when importing MusicXML files containing lyrics. This now fixed.
  • With thanks to Jeroen Neve: the 'hidden attribute' of extended items (hirpins, brackets, ...) was not always being respected. This is now fixed.

Mozart 15 version 15.0.2

20 December 2020

  • In 15.0.0 and 15.0.1 the 'updates' button on the Help tab will tell you when an update is available, but will not download it. You have to go to https://www.mozart.co.uk/support/ to get it. This is fixed here so that in future the updates button should work fully.

Mozart 15 version 15.0.1

19 December 2020

  • Thanks to Tony Caporn for reporting a problem with bar-number visibility. It turns out that the bar number was not being shown above the score system when the top staff is a conductor part. This is now fixed.
  • Thanks to John Filsak for finding a badly offset arpeggiation symbol. This is now fixed.
  • Thanks to Jeroen Neve for finding that one way of deleting an arpeggiation symbol caused a crash. This is now fixed.
  • Thanks also to Jeroen for finding that when copying and pasting a single text item, the wrong text was pasted. This is now fixed. While delving into this we also found problems with text containing an exclamation mark (!). For subtle technical reasons this was not being pasted correctly. This too is now fixed.
  • Thanks to Hugo Hölscher for reporting that rehearsal mark sequence was not being updated when a new one was entered via the bar-line properties dialogue box. This is now fixed.
  • Thanks to Richard Mills for highlighting problems with editing the duration of an existing caesura. As far as I can tell this was only a problem if the caesura was attached to a bar-line (and not to a note or rest). This is now fixed.
  • Thanks also to Richard for showing that start-of-line bar numbers were printed to low down on piano staves. This is also now fixed.
  • Thanks to Gunnar Nordstrom for finding that replacing a whole-bar-repeat symbol by the actual contents of the previous bar did not work correctly if the previous bar contained slash notes. This is now fixed.
  • An error has become apparent which means that the synthesiser will not have been getting an "all notes off" message at the end of play-back. This doesn't seem to have had any ill effect, but it's fixed now anyway!
  • Thanks to Barry Brooks for highlighting the fact that the "Insert start tempo" check box on the new file dialogue didn't work when the 'template' option was used. This is now fixed.


November 2020

No infelicities found yet, but here's a list of new features


  • ‘Slash’ note-heads are now available (in two slightly different styles).
  • Note heads may now be put in parentheses (in addition to the existing option of putting courtesy accidentals in parentheses).
  • The laisser vibrer symbol (a ‘tie to nowhere’) is available.
  • An optional continuation symbol is introduced for system breaks occurring in the middle of a bar.
  • Optional continuation symbols have been introduced for where the number of staves shown on a system differs from the previous system.
  • There is a greater degree of support for Accordion music, including a choice of 32 register (coupler) symbols.
  • Note stems may be hidden (for specialist purposes).
  • A greater selection of styles is available for 8va and other brackets over/under the music.


  • Bar numbers may be placed above or below and by the bar-line or centred on the bar.
  • The position of individual bar numbers may be fine-tuned to avoid collisions.
  • The position of ‘redirections’ (DS, DC, Fine, Coda,…) may be fine-tuned to avoid collisions.
  • Rendering of multiple bars rest is improved.
  • The background colour (‘paper colour’) for the representation of the music on the screen is now user-definable.
  • The caesura (break //) now plays back (with adjustable duration).
  • Pieces may now be marked with one of the modes: Major, Minor, Dorian Phrygian, Lydian, Mixolydian, Ionian, Aeolian, or Locrian (or left unmarked as before).

Interface improvements

  • A new, quicker mechanism, is introduced for entering triplets and other tuplets when typing in music.
  • An item (such as text or dynamics), having been entered in one part, may now be copied to all parallel parts, or to a selection of parallel parts, with a single command.
  • Individual items (such as text and dynamics) may now be copied and pasted.
  • Delete commands specific to items including dynamics and sforzandi have been introduced. These allow one to select a block and remove, for example, all dynamics from it, leaving other items unaffected.
  • Automatic beaming of groups of notes (including breaking inner beams) has improved.
  • On starting a new piece (by any of the three available methods) you can choose the ‘classic’ or ‘jazz’ music font.
  • The procedure for extracting musicians’ parts from a score has been refined and improved.
  • All musicians parts may be extracted with a single command.
  • Text font styles are now separated into two sets: one for text in the music (expressions, directions,…) and one for on the page (title, headers, footers,..). These scale with the music and the page size respectively.
  • Text font styles for the music now include standard (but user-definable) styles for expression markings, instructions, and tempi (as discussed by Elaine Gould in ‘Behind bars’).
  • Many operations which previously required one to show the virtual conductor stave, may now be effected transparently, without actually showing it.
  • When hidden staves are shown for editing, the screen page image expands to allow this to be done smoothly.
  • Export of abc files is improved.
  • Mozart now has ‘page layout files (.mzlayout) in addition to score template files (.mzt). Score templates continue to be available for creating a new piece, and contain both score structure and page layout information. Page layout files contain only page layout information, and are used, for example, when extracting parts from a score. A page layout may also be imposed from a .mzlayout file on to an existing piece.
  • A page layout may also be imposed from a .mzlayout file on to an existing piece.
  • The overview of text boxes has improved.
  • There is a new ‘Help’ category tab replacing the drop-down list of help-related topics.
  • The mouse-wheel action when the Ctrl key is pressed has been adjusted to conform to its behaviour in Microsoft’s applications.
  • A new tablature command is available to move a note from one string to another, automatically adjusting the fret in order to preserve the pitch.
