Dmuse: Score printing

Starting from Stage2 MuseData files

When starting from MuseData files, the data must be converted into i-files which are then converted into page files. To convert the MuseData files into i-files, you must use the autoset program.

Directory preparation

Before running autoset, you should create several sub-directories in the main working directory. The main working directory for a work will contain a stage2 directory which contains all of the MuseData files for all parts of all movements for the work. The autoset program expects a certain directory structure to exists, so if you try to run the program without the proper directory structures created, the program will stop with an error message.

Before starting autoset, you should make sure that there is a sub-directory in the same directory as stage2 which is named outputs. Within outputs, you must create an arbitrarily named sub-directory into which the output files from autoset will be stored. Typical sub-project directory names might be score when creating a full score, or parts when preparing instrumental parts. And finally, within the sub-project directory, you must create an additional sub-directory called i-files.

Within the i-files directory, autoset will automatically create movement sub-directories which mirror the directory structure that is found within the stage2 sub-directory in the main working directory for the work.

This directory structure can be prepared from within dmuse by using the file manager which is opened with the F4 function key.

Running autoset

State of Dmuse immediately after starting autoset.

To start autoset go to an empty window, such as #5 by typing Keypad 5. If window 5 is not empty, but the contents does not need to be saved, press Home to get to the top of the window, and then press Shft+Keypad -.

To start autoset, first press Shft+Keypad * to start the zbex interpreter. Once the zbex interpreter is running, the string "[*]" will appear on the top right border of the dmuse window. If this mark does not appear, then you will have to edit the Dmuse INIT file to enable the zbex interpreter. The zbex interpreter will print the text "Ready for program". Type the name of the program to run, which in this case is autoset, and then press Return. Zbex will then start running autoset. The figure on the right demonstrates what should happen in Dmuse at this initial stage when starting autoset.

Music size

The first question that autoset asks is:

  Enter note size (<return> = 14: x = non standard parameters)

This question sets the font size of the music. Font size 14 means that there are 14 pixels between staff lines (in 300 DPI). Font size 14 is the standard font size for scores (you can press return to use that default size). The smallest possible size should be 6. Parts are usually typeset in size 21. Not all font sizes are available.

Compression factor

The next question which is asked is:

  Compression factor (<return> = none)

You should probably press return for the default compression factor of 100. For denser music, use a smaller value, such as 90. For greater spacing between notes, try something like 110. Good results are usually in the 92-96 range. Sometimes 85-87 might be needed. This value is typically used to get the last page to contain a full page of music.

Source file location

The third question that autoset asks is where are the MuseData files located:

  Autoset performs the first step of the music typesetting process.
  Autoset takes stage2 source files as input and produces non-page
  specific intermediate files.  Since the stage2 directory contains
  source files for a variety of uses, you need to specify the group
  (i.e. sound, score, skore, parts, short or data)  that you want 
  autoset to work on.  Enter the source library and group name now.
  
  Source library?

At this point it is useful to have the resident file manager point to the main working directory or one of its parent directories. The term library in Dmuse is equivalent to directory or folder. For example if the musedata files are stored in /usr/local/apps/musedata/baroque/corelli/chry/trio/op1n12, it might be useful to set the file manager to be looking at the directory /usr/local/apps/musedata/baroque/corelli/chry/trio. If you set the file manager to point to this directory, then you can answer the above question like this if you want to generate a score for the first movement:

   op1n12/stage2/01

Group name

The autoset program then asks for the group name to process. The stage2 files contain a Group Memberships: line which should contain one or more membership labels. Type the name of an existing group for this question:

   Group name? (default = data)

The most common group for generating a score is "score". When generating parts, a typical group name would be "parts". Type score for this particular example of typesetting a Corelli sonata movement.

Output directory

Next autoset asks where the resulting i-files that it creates will be stored:

  Autoset works on only one movement at a time.  The output library
  (for i-files) must already be allocated.  Autoset will name the 
  output files (i-files) according to the order of the input files
  in the group; i.e. part 1 from the input group becomes the i-file "01".
  Autoset can work on a range of parts within a group.  You will be asked
  to provide this range.  Enter the output library and range now.
  
  Output library? (Enter a blank line to get default output library).

In this case type:

   op1n12/outputs/score/i-files

The outputs and outputs/score/i-files directories must already exist before you continue with the program. This is the sub-directory into which all of the data from autoset will be stored.

Number of parts

Now autoset will examine the stage2 files for movement one and identify how many parts are present in the score group membership:

  There appear to be 3 parts in this group.  Enter the first and
  last numbers of the range you wish, or simply type <Enter> to
  process all of them.

In this case, we are preparing a score (not a part), so press Return.

Finishing the processing

State of Dmuse after autoset has finished processing data.

At this point autoset has all of the information which is necessary in order to complete the processing of the data. The figure on the right shows the status messages which are displayed in Dmuse as autoset generates the output i-files.

Starting from i-files

At this point you should have a set of non-page-specific i-files within the sub-directory outputs/score/i-files
