I decided to reinstall Qmidi, so I delete the library and preferences and was wondering if there is a way to export/import the whole library's metadata (title, album, key aso.) as a csv or excel file, so it can be easily edited?
If it's not possible, then this would be a cool feature to add :)
I too would love to see the ability to export the library to a csv file. I'm not having an issue with the library like the previous user. I just don't find the library robust enough for my use. For example, I work with a lot of hymns, for which lyrics are often written by someone other than the composer. The library only has a field for composer, not the lyricist. I've added the lyricist to the comments field, but searches don't work on that field. (And I've found that searches are not entirely reliable in others contexts as well.) A separate field for "Tune" would also be useful, e.g. Hyfrodol, Tallis Canon, etc. One tune may be used for many different hymns. A separate field for meter would also be useful. Any hymn that has the same meter as a different tune can also be sung to that tune.
I would not expect QMidi to add all those features, but that illustrates why it would be useful to export the library database to be able to add such fields in a database of my own creation. Another example is sharing data on my collection of hymns, for example with the hymnary.org website.
I'm not holding my breath, but I'd find such a feature very useful.
The good news is that you can use the pasteboard to copy your library data as tab separated text.
I've just tested this on my 22K song list and it worked like a charm (may require some time to process, don't care).
NB: Only displayed data is copied so check which columns are enabled.
You can alternately open the "(Home)/Music/QMidi/QMidi_Library.sql" file with any SQL database reader.
