meico's Issues

Support for MusicXML format

Good day. Is it possible for meico to receive an input in a MusicXML format (.mxl) and convert it to others formats currently supported by meico? Thanks.

MSM resolve repetitions duplicates xml:ids

When MSM resolve repetitions is called, elements are copied, so does their xml:id. The resulting file contains multiple uses of the same xml:id which is not XML conform.

App cannot be launched

Hi there,
I just stumbled over your project and wanted to give it a try.
However, launching your app with java -jar meicoApp.jar does not work.
With Java 1.8:

Exception in thread "main" java.lang.UnsupportedClassVersionError: javafx/application/Application has been compiled by a more recent version of the Java Runtime (class file version 54.0), this version of the Java Runtime only recognizes class file versions up to 52.0
        at java.lang.ClassLoader.defineClass1(Native Method)

With Java 11:

IMHO you should consider switching to OpenJFX.
Otherwise, you might want to improve your README with hints from here:
javafxports/openjdk-jfx#237

Add XSLT interface to window mode

It would be nice to have the XSLT functionality accessible also in window mode.

meicoApp.jar doesn't work with openjdk

On my openSUSE GNU/Linux box, calling

java -jar meicoApp.jar

Is this expected? I would expect that OpenJDK 11 is recent enough for running Java 1.8. What am I missing?

Audio playback

Integrate audio playback in class Audio. Add a corresponding button to the window mode gui.

For the encoding of orchestral scores, we make extensive use of @sameas for rests and notes shared by two instruments (encoded in two layers) on the same staff. Otherwise, full encoding in all layers would result in unwanted double rendering of elements.

In the example shown, the quarter rest in m. 11 of the oboes is fully encoded in layer 1 (= oboe 1) but with @sameas in layer 2 (= oboe 2), i.e. @dur is found in layer 1 only; the rest in layer 2 has to take the duration from the rest it is pointing at. MEICO currently ignores the rest in layer 2 with the effect that oboe 2 starts on the first beat of the measure instead of the second (echoed by oboe 1 on beat 2). This can be observed throughout mm. 11-14 in the oboes as well as in m. 18 in the horns (eighth rest).
Here is the data:

Support for @sameas, especially for rests, is highly desirable. Otherwise orchestral scores cannot be played with accuracy in MEICO.

Possible solution

The both problems could be solved if MEICO would first check in the <meiHead> if there is information about the instruments. In our case, there is a link via staffDef@decls to the MARC instruments vocabulary.

Arpeggio direction in MEI-to-MPM export

Seems like the direction of an arpeggio, exported from MEI to MPM, is downward by default or inconsistent, maybe depending on the order of appearance of notes. Investigate further!

Expand repetitions

It would be nice being able to expand repetitions and prima e seconda volta in MEI files so that the relevant sections are copied several times behind each other.

Support for <supplied>

Meico seems to skip elements wrapped by a supplied element. This becomes particularly evident in cases of editorial additions of accidentals.
In the following example, all three notes should sound alike, but Meico plays the third one as c natural.
In the first measure, the sharp is coded as an attribute, in the second measure as an element which is an equivalent to the coding in the first measure; in the third measure, the sharp is wrapped by a supplied element, marking it as an editorial addition. The sounding pitch should remain the same, i.e. c sharp. As a fix, Meico should just ignore the supplied element, leaving the accid intact however.

Negative Timing in Performance Rendering

Whenever notes are shifted into negative time (e.g. via an articulation delay or an arpeggio on the first chord), these note are cut at date 0. Maybe add a delay at the end of the rendering pipeline.

MEI coverage documentation

It would be nice to have a documentation of which MEI elements are supported and how they are interpeted by meico.

Portato

The combination of legato and staccato should result in a portato articulation.

I achieved this in my local copy by inserting here the following piece of code:

// Check if there is a staccato articulation at the same time. If yes, do not continue 
// with a slur, but insert a portato articulation instead and remove
// the already existing staccato.
ArrayList<KeyValue<Double, Element>> simultaneousElements = map.getAllElementsAt(date);
for (int i=0; i<simultaneousElements.size(); i++) {
  Element otherEl = simultaneousElements.get(i).getValue();
  if (otherEl.getAttribute("name.ref").getValue().equals("stacc")) {
    map.removeElement(otherEl);
    this.addArticulationToMap(date, "port", slurid, noteId, map, articulationStyle);
    return;
  }
}

I'm not really familiar with the way things are being handled in Meico. If this is the way, I'll be happy to do a PR …

File names with capital extensions

In window mode, files with extensions in capital letters (e.g. ".MID" instead of ".mid") are not correctly recognized in gui mode.

Expansions

Add support for MEI expansion elements.
This also means to add processing of MEI section and ending elements beyond what is done right now.
Convert them to MSM sequencingMaps.

Return meaningful exit codes

When meico is used as a command line tool, it should return a meaningful exit code.
Example:

 0 - Everything went fine
...
64 - Command line usage error
65 - Input file invalid
66 - Input file not existent or not readable

A few cases already have de facto standardized exit codes, see http://opensource.apple.com//source/Libc/Libc-320/include/sysexits.h

Java 7 code makeover

With audio export and SoundFont support we had to dismiss Java 6 compatibility. Now, some code makeover is appropriate. Esp. the terrible if-else chains that where necessary for strings can now be replaced by switch-cases (support strings since Java 7). Try-catch exception handling can likewise be set more compact now.

Use meico like a library to convert midi

Hi, i need to use meico like a library to convert files from midi to mp3. How can i do this? Exists a function that i call directly? thanks

Default choices for variant

Whenever MEI encodes variants meico jumps over it and leaves an empty spot. It makes no decision for any variant. It would be nice to have a method that makes some kind of default decision to have at least one "complete" piece of music in the output. To get any other decision or combination of variants, the user should apply MEI Sequence Editor to create an unambiguous MEI file.

Update meicoPy.py

Update meicoPy.py:

add XSLT interface
add MP3 export

command line utility does not work with v0.8.0

I'm getting:

Started: java -jar "meicoPATH\meico.jar"  --wav -t 100  filePATH\dmeref_499-003_5859.xml
meico v0.8.0
Process ended with exit code: 0

the code above is from oXygen notification panel, but the same issue prompts when using the command line
until the v0.7.10 everything worked fine with the same command
meicoApp.jar can be run from the command line
Maybe I missed some changes in the usage?

New GUI

Since introducing XSLT support the conversion path became branched which the current graphical user interface cannot display. A new GUI is needed.

The new one should also implement better playback functions (for MIDI and audio) and allow winding and pausing.
