# Changes in LenMus Phonascus

## LenMus Phonascus 6.0 (February 12th, 2022)

- The most visible change is the main window, that now allows direct access to all content, to facilite navigation. The toolbar has been removed, as was of little utilitty and made it more complex, to new users, to find the relevant content.
- The exercises has been sequenced in two levels with predefined configurations, to help students configure them for their skill level.
- Two new chapters added to the books: one about anacrux start and another one on chords. Music reading exercises now will include anacrux start.
- Extensive tests done and many bugs fixed
- The Spanish version of the music reading books have been reviewed and the chapters reordered, to follow a different learning progression. If you would like to continue with the old books they are stil available.
- Experimental features whose development will not continue, such as the score editor, have been removed, to simplify the code and program maintenace.

## LenMus Phonascus 5.6.0 (March 1st, 2020)

The main objective of version 5.6.0 is to avoid problems with the sound when installing LenMus. In previous versions, the user had to configure a MIDI synthesizer and sometimes even install it, and this caused problems. This now has been solved:

- LenMus includes now a preconfigured internal MIDI synthesizer and, therefore, the user no longer needs to install a MIDI synthesizer or configure the program to use it.
- The MIDI assistant has been removed, since the user has nothing to configure after installing LenMus. But, for greater flexibility, LenMus now includes a MIDI configuration option, to allow you to configure the internal synthesizer (for example, change SoundFont) or allow the use of an external MIDI synthesizer instead of the internal one, in case the user prefers to use specialized hardware or other MIDI synthesizers.
- Add link in welcome window to facilitate users to report errors and make suggestions
- Fix bug preventing to translate the "Cancel" button.
- Fix bug: MIDI instrument names not properly translated when changing the language.

## LenMus Phonascus 5.5.0 (February 7th, 2020)

This is a maintenance release to add the translation to the Greek language and some few small improvements, and to fix bugs. The main changes are:

- The translation to the Greek language has been added. Thanks to Avgeris Tsironis (Αυγέρης Τσιρώνης).
- The cadences generator have been re-coded to remove bugs in Cadences exercises.
- Updates the MS Windows installer for Windows 10 x64.
- Improves metronome by adding a metronome settings window and allowing to select the beat note value.
- Keyboard buttons Page Up/Down are now operative in eBooks.
- More visual tracking options during playback.
@l
- Fix to display the Study Guide in the selected language.
- Fix bug in options for theo idfy/build interval and for cadences exercises, causing to ignore some selected options.
- Includes de latest Lomse library with improvements, mainly in MusicXML import and music notation support.
- Links for features not yet fully operational have been disabled.
- Fix error in figure in Theory and Harmony eBook.

## LenMus Phonascus 5.4 (September 26th, 2015)

The main goal of this release is to simplify LenMus installation. I've changed the way in which LenMus is built and installed, removing the dependency from Lomse library that caused a lot of problems. Unfortunately, it is too costly to prepare a release without including all the new code in development and, thus, this release includes a lot of new features not yet finished, but this new code is, by default, disabled.

The main changes are:

- Changes for including a score editor:
  - Changes in main menu:
    - Added 'Edit' menu item, with some sub-items (undo, redo, insert, enable edition). When opening a document it is, by default, non-editable. You must enable edition by selecting 'Edit > Enable edition'. Edit > Insert' includes test code for inserting headers, paragraphs and scores.
    - Added more 'File' menu items:
      - 'File > New', for creating empty documents.
      - 'File > Save' and 'File > Save as'.
      - 'File > Close'. Also, when closing a document, checks if it has been modified and asks for saving it before closing.
      - 'File > Convert' menu item, for converting a Document to latest format version.
    - Added menu option 'View > Show voices in colors' for displaying each voice in a different colour (works also in read only mode).
  - More tools added:
    - A 'Command console', to test edition commands without using GUI.
    - A 'Toolbox' for containing all tools related to document edition:
      - It is automatically displayed/hidden if edition is enabled/disabled.
      - It also admits 'mode' (personalized configurations so that each exercise or edition mode can have specific tools).
      - It is also automatically reconfigured when the active document changes, so that appropriate tools for each document are presented.
    - A 'Score wizard' for creating scores from templates.
  - Shortcuts:
    - Added code for a shortcuts system, globally managed.
    - Added option dialog for customizing shortcuts.
  - All music elements (notes, rests, barlines, clefts, etc.) can be entered from keyboard. Navigation keys also operational.
  - Support for edition via 'drag and click': Barlines notes and rests can now be added by drag and click.
- Changes for preparing more exercises and new features:
  - Added and implemented FullEditorCtrol and DictationCtrol classes, for allowing to use the score editor in music exercises.
  - Added class ScoreComparer for correcting user solutions.
  - Changes in composer for creating pickup measures (Thanks to Camilla Tassi).
  - New dialog for metronome in 'Menu > Tools', to facilitate more features, such as setting tempo by tapping.
  - Added help system. Help menu now includes: 'Users guide', 'Study guide' and 'Editor quick guide'.
  - Added code for importing MusicXML files. Importing files merged in 'File > Open'.
  - Fixed bug in composer resulting in bad pitch assigned to some notes.
  - Added button to hide or show TOC panel for books.
- Other changes:
  - All the code has been updated for using wxWidgets 3.0.
  - I've designed a new work-flow for translating the users oriented documentation, such as 'Users' Guide' and the 'Editor quick guide'. Several scripts developed for managing all this.
  - Added option, in preferences dialog, for enabling all the features not yet finished ('Preferences > Other > Enable experimental features').

## LenMus Phonascus 5.3.1 (April 28th, 2013)

Version 5.3.1 is focussed on fixing bugs, in particular on those causing unexpected program termination. This version also completes translation to Chinese and adds options for clefs reading exercise:

- Full translation to Chinese.
- Changes in exercises to display more messages to guide users.
- Added options to clefs reading exercise for choosing clef and notes range.
- Bug fixes:
  - Occasional program termination when moving to another exercise.
  - In compare interval exercise the option to start both intervals with same note was not working.
  - In interval exercises sometimes an strange error message saying that 'Not possible to generate valid interval' was displayed.
  - Button colour was removed as soon as mouse moved over the button.
  - Other bug fixes and changes related to exercises.
  - Moved to Lomse library version 0.14, as it fixed many bugs.
- Technical changes: Logger class removed and replaced by Lomse logger.

## LenMus Phonascus 5.3 (November 29th, 2012)

- Restored all other missing features, present in previous version 4.2, that were disabled in 5.0:
  - All exercise modes (learning, practise, exam, quiz) restored.
  - Right/wrong sounds when answering an exercise restored.
  - After answering an exercise, the answer buttons will play the button sound when clicked.
- Fixed bug #1074909: Exercises on intervals in TheoryHarmony, lesson 4.1: not for level one. Settings for these exercises were for level 3 and have been restored for level 1.

  - Countoff checkbox is again operational in all music reading exercises.
- Fixed bugs in music scores composer, introduced during source code migration to 5.0.
- Fixed bug preventing to display release notes in current language.
- Fixed bug in key sign. identification preventing to display the answer string.

## LenMus Phonascus 5.0 (July 8th, 2012)

Version 5.0 is, mainly, an experimental version using the new Lomse library (http://www.lenmus.org/en/lomse). It is an update of all LenMus Phonascus code, with some addidional improvements:

- Two new exercises are included:
  - Notes identification.
  - Tonality identification.
- All existing problems with zooming, relative size of scores and text, and rendering have been solved
- The build system has been change to CMake. And there is now a Linux package.
- Now there are independent Windows installation packages for each translation. With this, it is now possible to update a translation at any moment without having to wait for a new program release. This creates more work for me but solves the previous problem of having to wait for all translators before releasing a new version.

As you can see there are no many new features, as all efforts has been in rewriting LenMus Phonascus code:

- All code related to analysing, parsing and rendering scores has been isolated and moved to a platform independent library (the Lomse library). The idea was that this code could be used by any other projects and that it can be better tested to get the best code quality.
- The eBooks format has been changed so that now they are fully written in LDP.I have redesigned the way in which exercises are created and displayed. Now the LDP score description language has been extended so that it can now describe not only a score but full documents, with any content: texts, images, scores, exercises, etc. The reason for this change was to remove the need to use a web browser to display the eBooks. Until now, the exercises were displayed as HTML pages by using an internal, very limited, web browser. Due to its limitations and to the hacks I had to do to display scores, old LenMus Phonascus releases had some problems of difficult solution that are now solved.

All these changes have implied a lot of work. Due to this, I have not yet finished rewritting all existing code. As a trade-off between features and time to release version 5.0, I've decided to release version 5.0 without including some features existing in previous 4.2 version:

- The score editor is not yet included.
- Reduced functionality in some points:
  - Exercises supporting only exam mode (Quiz counter ctrol in exam mode).
  - No right/wrong sound

All missing functionality will be restored gradually in future versions and new functionalities and exercises will be added.

## LenMus Phonascus 4.2.2 (March 21st, 2010)

- Critical bug fixed in score renderization that could cause a crash in any score when rendering it.
- Updated Basque translation

## LenMus Phonascus 4.2.1 (March 8th, 2010)

- Fixes a critical bug producing a crash at start if monitor resolution is grater than 1024 x 768 pixels.
- Language can now be changed without re-starting program

## LenMus Phonascus 4.2 (March 7th, 2010)

The main changes introduced by release 4.2 are the following:

Exercises and eBooks

- Lessons in eBook TheoryHarmony: Added six lessons on scales, lesson on intervals changed.

Bug fixes

- Score layout algorithm has been rewritten from scratch using a test driven approach. A lot of renderization bugs have been fixed. Automated tests now in place for error detection and quality assurance.
- Critical bug fixed: sometimes crash when clicking with mouse at end of last bar.
- Inserting note before barline creates the note at next bar, with incorrect time position.
- LDP parser incorrectly imported real numbers lower than 1.0 and greater than 0.0.
- Clefs bounds incorrectly computed, adding more space than necessary for layout and for selection.

Translation

In order to simplify and reduce work for translators, Langtool, the lenmus tool developed for eBooks translation, has been modified to improve it and to add support to translate also help documentation, release notes, web pages and other documents.

Also changes to improve program translation by not breaking sentences at certain tags (i.e. emphasis, link, etc); a lot of refactoring to simplify maintenance and addition of more tags. Support for styles (eBook style, variable footers) introduced.

## LenMus Phonascus 4.1 (January 7th, 2010)

The main changes introduced by release 4.1 are the following:

The score editor

The score editor is much more stable but it is not yet finished and continues in beta status. The editor includes now more features but few of them will be noticeable in this release. The most visible are:

- Data entry using the mouse. The user interface (including the toolbox) has been improved and now data entry using the mouse (point and click) is available. Data entry using keyboard has been restricted to notes and rests (but mouse can also be used). For all other, the mouse is now mandatory.
- Lines, ties, and, in general, geometric figures, are now editable by dragging control points.
- Figured bass symbols. Now it is possible to add figured bass annotations to the score. This was required for the planned exercises on figured bass to be included in a coming version.
- Notes stem direction now editable. The tool box now includes buttons to control stem direction.
- The score being edited is now automatically recovered after a crash. The score editor is much more stable, as a lot of debugging was done and all known bugs have been fixed; nevertheless, it is still not finished and continues in beta status. But now, after a program crash you will not loose (normally) the score being edited and it will be recovered automatically when you run again the program.
- Automatic upload of a 'forensic log'. I need your help to debug the score editor. Take into account that most of my time is devoted to programming, not to use the program. Therefore you probably will catch more errors than me!. In order that you can collaborate in this task, the program now saves data about the score being edited and the action performed, and if the program crashes, it asks for your permission and sends me a "forensic log". It is a simple file, in text format (you can open it at see its contents) and it does not contains any identification data of any nature (personal, equipment, Internet address, etc). It only has the score being edited an the actions being performed. Thanks for your collaboration!

Among the 'hidden' improvements the following should be mentioned:

- Support for 'Score processors'. There is a need for tools to process (or alter) a full score. For example, a tool to transpose a score, to add colours to voices, to make a piano reduction, etc. I call 'score processors' to these type of tools that process the whole score and can alter it. Support to develop and use score processors has been added and it is currently being tested with the four voices harmony and figured bass exercises that will be included in coming releases.
- Support to use the score editor for exercises. The problem is presented as a score that the student has to modify. As the full editor is used, the student can save the score so that he/she can later continue the exercise. This facility is currently being tested with the harmony and figured bass exercises.
- Customizable editor modes. For exercises using the score editor to elaborate the answer (for example: dictation exercises, harmony exercises, etc.) there is a need to customize the score editor for the needs of a particular exercise. For example, in the four-parts harmony exercises the editor is restricted to use only four voices. To implement this idea, the score editor now supports 'editor modes'. An 'editor mode' is just a set of restrictions and customizations that forces the score editor to behave in a predefined way and customizes the toolbox to include different tools.

Exercises and eBooks

The interval's exercise has been reviewed and splitted into two exercises, one to identify intervals and another one to build them. The identification exercise has been re-structured into four difficulty levels. The exercise settings has been rebuild and there are now more options.

eBook Theory & harmony now includes a new chapter on intervals. But only the first lesson is included. Sorry! I have no more time!

The eBooks license has been changed to Creative Commons Attributtion-Share Alike License. I think this license is clearer than the GNU Free Documentation License and is compatible with it. This changes also simplifies life for using texts from other free public sources or for integrating LenMus texts in other public sources.

The Leitner learning methodology is now included in some exercises. Originally, LenMus exercises were not based on any particular learning methodology. Questions were selected just at random and no student performance data was saved. Version 4.1 now includes support in some exercises for a spaced repetition learning technique, also known as Leitner method or flashcards method. A database to save user data about exercises and answers has already been added and I have started to modify exercises to include four working modes: 'learning', 'practising', 'exam' and 'quiz'

- In 'learning' mode the program analyses your answers and schedule questions to systematically covering all the subject and to focus on those questions that are troubling you. This mode is the most systematic one and asked questions are adapted your learning needs, to minimize your study time and optimise your learning rate. Your performance data is saved and the next time you return again to the exercise, the program takes care of asking questions to ensure an optimal learning path. The result is, ideally, a reduction in the amount of time needed to study a subject and the assurance that the subject has been systematically reviewed. This mode is based on the 'spaced repetition' or 'Leitner method'.
- In 'practising' mode the program uses your performance data, saved in learning mode, to choose questions. It selects questions at random but giving more probability to those that are troubling you. Your performance data in this mode is not saved. This mode is useful when you have finished your daily assignment and you would like to practise more.
- In 'exam' mode, neither your saved performance data not your answers to previous questions are taken into account to formulate the next question. At any moment, all possible questions have the same probability of being asked. This mode is useful for testing your knowledge before taking an examination, but is less useful for learning.
- The 'quiz' mode is similar to the 'exam' mode but two answer counters are displayed and questions are accounted in both counters: one in first counter and the next one in the second counter. This mode is useful to work in pairs or in teams at classroom.

User requests and other changes

1. Some users requested to have a count off before starting any score play back. Count off has been added for scores opened in the editor and for scores in music reading exercises.
2. I received some reports on problems when using low screen resolutions or big size icons in the toolbar, as the buttons didn't fit on the available space and some of them were not visible on the screen; as the actions performed with these buttons were not available on the main menu the user could not interact with the program. Now:
   - all toolbar actions are also on the main menu, and
   - the toolbar automatically resizes and splits to fit in the main window.

## LenMus Phonascus 4.0 (January 17th, 2009)

As the version number change suggests, release 4.0 is major update in the program code and functionality. The main changes are:

Inclusion of a score editor (beta status)

The major change from previous release 3.6 is the inclusion of a score editor (although in beta status). The score editor is not yet finished, as much more features have to be added, but the included features are operational, and allows to create simple scores, even with several instruments and voices. Nevertheless, the editor is in a preliminary state (beta status) and it is mainly useful deal with simple scores with one voice per staff. Many voices per staff are also supported but facilities to automate layouting task and taking automated decisions, such as automatic voice assignment, automatically setting up stem direction in notes to avoid collisions between stems, and other facilities, are not fully operational and in some cases produce poor results. Also, at current development stage, it is not possible to deal with:

- lyric lines
- slurs
- dynamics, articulations and other symbols
- cue/grace notes
- rehearsal marks, coda, segno and related symbols
- nested tuples
- figures: lines, boxes, circles, other

These missing features will be added in coming releases. The basements are now there, so I expect to add much more features in short time.

One of the issues that has demanding me a lot of time is the user interface. I would like to find a simple and intuitive interface, but the complexities involved in editing a score makes this difficult to achieve. Therefore, do not assume the user interface is finished as I will continue experimenting with different approaches. Your suggestions are extremely welcome, specially if you have experience in using other score editors.

Change of license to GPL v3+

The extensive code re-writing required to include the score editor and the fact that including a score editor is a major change in program features are the main reasons to change release number to 4.0 instead of 3.7.

With release 4.0 I also have changed the program license to the new Free Software Foundation GPL V3+. With this change, I expect to better ensure your rights to use LenMus for free, to have access to source code, and to be able to distribute it to others and to modify it. The change to GPL v3+ is also a reason to change the release number to 4.0. With this change it will be more identifiable which license applies to which lenmus version:

- lenmus 1.x - freeware. Source code not available
- lenmus 2.x & 3.x - GPL v2+
- lenmus 4.x - GPL v3+

Welcome page

A welcome page has been added to facilitate access to the different features and to have easily available on startup:

- eBooks
- The score editor
- Latest open scores
- Useful links and documentation

Other changes

Version 4.0 does not include new music eBooks or exercises. But bugs detected in previous versions have been fixed.

Three new translations has been added: Basque, Galician and Italian.

## LenMus Phonascus 3.6 (December 1st, 2007)

- Improvements in the automatic music composer:
  - The composer was modified so that in the final measure it never adds a note longer that a quarter note if the composed piece only uses quarter notes. This was needed for Music Reading Level 1 eBook, for the initial lessons.
- Improvements in the internal score model to support more features:
  - Support to include graphical objects (arrows, lines, circles, etc.) in a score. For now only lines are implemented.
  - Implemented metronome mark notations.
  - Added support to set up the size of a measure by specifying the barline position.
  - Added support for fermatas on notes and rests.
  - Added support to have global, inheritable options in all score elements. Implemented support for the following options:
    - Option 'Staff.DrawLeftBarline' to control left barline drawing.
    - Option 'StaffLines.Hide' to control staff lines drawing.
    - Option 'StaffLines.StopAtFinalBarline' to allow for staff lines going to the right paper margin instead of finishing at the final barline.
    - Option 'Staff.UpperLegerLines.Displacement' to shift the first upper leger line so that it is closer/further than normal spacing. The other leger lines spacing is not changed.
    - Options 'Render.SpacingMethod' and 'Render.SpacingValue', to allow for more control of score renderization.
- Improvements in score renderization:
  - Fixed spacing method implemented.
  - Fixed bug [#1715968]. Proportional spacing of notes is now working.
  - Do not add spacing after barline if barline is not visible.
- Improvements in LDP language to support the new features. New tags added:
  - Implemented simple notation 'fermata', and compound notation '(fermata [above | below])' on notes and rests.
  - tag 'metronome' to define metronome notations.
  - tag 'graphic line' to add lines on a score.
  - tag 'spacer' for better controlling staff space.
  - tag 'opt' to add global, inheritable options to all other tags.
  - Added support for strings enclosed in double simple quotes as an alternative to double quotes.
- Several bug fixes:
  - Bug fixed [#1724988]: Crash if program is closed while playing intervals in aural training compare intervals exercise.
  - Bug fixed [#1715979]: When you have a score open, the 'show/hide navigation panel' button shows as active but you cannot click on it.
  - Bug fixed [#1715953]: In the Midi configuration wizard the drop downs in the wizard should not be editable.
  - Bug fixed [#1715959]: Focus problem. In the configuration window when you check the proxy configuration but do not fill it in and then change the focus to section 'language', the category selector changes but the focus remains on the Internet section. Alternatively you could generate a warning message and leave the focus on the Internet section.
  - Bug fixed [#1715963]: Repeated quick acceleration letters in options, menu labels. The English text has the same letter as quick key for bottom and right labels.
  - Bug fixed [#1715965]: Rests in a group of tied notes are not rendered in the right position.
  - Bug fixed [#1715968]: Proportional spacing of notes is not working.
  - Bug fixed [#176634]: Program crash if closed while playing a score.
  - Bug fixed [#176635]: Crash if program is closed while playing an exercise (L2_MusicReading).
