Winter Releases

In addition to the usual bug fixing, a common pattern across all projects are the changes related to the transition to Qt6, still experimental but mature enough, while keeping compatibility with Qt5. One stopper in this transition is the removal of the QTextCodec class in Qt6 core libraries, moved to the Core5Compat module, risking to be definitely removed at some point in the future. Some methods in Drumstick::File that depend on this class are deprecated now. This functionality is key for data preservation when parsing/importing MIDI files containing text metadata (titles, comments, names, copyrights, lyrics, markers, ...) encoded in any random scheme available in the last 30 years. But the alternative in Qt6 is the QStringConverter and related classes that only supports a very limited set of encodings, mostly Unicode.

This problem deserves deeper thoughts...

If we were talking about pure text files, this could be solved using for instance the iconv command line Unix utility, that converts text files from one encoding to another, for instance from ISO-8859-5 (Cyrillic alphabet) to UTF-8. Then, the new text file encoded in Unicode could be processed by a Qt6 program without limitations. But MIDI files are compact binary structures that can't be processed directly with that utility.

The second root of the problem comes from the SMF nature itself. The Standard MIDI File format was created as an interchange file format, so the music created in sequencers using proprietary storage formats could be exported and retrieved by another sequencer. Sequencer machines and software at one point become deprecated, stopping to work, and can't be used anymore. Composition files created in those systems are now digital garbage for the trash bin, except if the author took the precaution of keeping exported MIDI files. Those are now the equivalent of modern digital manuscripts, which we try to preserve and keep them readable for the foreseeable future within our musical applications.
