... would be cool. Advantage would be:

Would be cool if JJazzlab would support this importing feature one day. Thanks friends.

Here is one example of output from a song of reaper forums: Estimated chords for The Reckoning - Final.mp3, which you can find here, http://forum.cockos.com/showthread.php?t=68410 :

What is the number ? Thought it would be the chord position but it seems not...

michaelsjackson commented 1 year ago

Number is time in seconds. However there are other VAMP plugins as well, which could output bar and beat numbers. Or tracking bpm tempo. From all those information, tempo in bpm, time in seconds, bar number beat number, plus the estimated chord, all could be mapped correctly to JJazzlab-X. If this is interesting for adding to JJazzlab-X, I can investigate more, how it could be done via command line using sonic-annotator. Then as output we would have a few text/csv files for the above parameters, which JJazzlab-X would need to import.

jjazzboss commented 1 year ago

If you have a file with bar/beat number on each chord name (ideally + time signature), then adding an importer in JJazzLab is quite easy. You just need to implement this interface: https://github.com/jjazzboss/JJazzLab-X/blob/master/Song/src/org/jjazz/song/spi/SongImporter.java

But problem with automatic chord recognition is that there are always errors (in your file sometimes there are 2 chords in .5 seconds!) and you spend a lot of time fixing the chords...

michaelsjackson commented 1 year ago

If there would be a CSV song import function, and I would know the required order of columns I could try to create such a CSV via the command line. Would such a CSV line be enough for example, giving one line (with bpm redundancies). bar, beat, time_signature, bpm, chord_name Above example would contain 5 columns. Which is the smallest possible beat distance for entering chords? 1 beat? Or can I also have values like 0.5 beat, or 0.1 beat for example?

Regarding errors, yes, possible, depending on the used song, but still better than nothing. For simple song types it should work quite well I guess. Quick editing for corrections I would find easier than typing all from zero yourself. Using this technique one could do many more quick experiments, mainly, choosing a song you like, then playing along with your real instrument like a guitar for example. You could take any song in the galaxy! :)

jjazzboss commented 1 year ago

To make it simple a csv file is good: bar, beat, chord_name Yes beat can be 0 or 1.25 etc. With this format I can easily make an "import chords" feature: it will just insert the chords in the current song. If a chord is "out of range" (e.g. beyond last song bar, or if the beat position does not match the time signature), I'll issue a warning.

michaelsjackson commented 1 year ago

For 4/4 time signature would not those formula calculate the correct bar and beat values, if you know the constant bpm of the song (assuming the song having constant bpm)?

time_minutes * (bpm/4) = bar
time_minutes * bpm = beat

Implemented in 4.0

michaelsjackson commented 6 months ago

Happy christmas and holidays dear jjazzboss. Thanks for the new version and implementing this feature. Tested it quickly, it seems working. A few observations: 1- When using CSV as coming from sonic-annotator, e.g. Fm shown as "Fm", this will not work. Removing both " solves the situation. 2- When there is no chord in zero position an error message is shown. Holding the tiny symbol at the bottom, pulling it to time zero solves the situation. 3- Having an older linux version e.g. ubuntu 18.04 might only have an older fluidsynth package. Solution is then using the .zip package you gave hopefully. Then I can still continue with my older fluidsynth program (via qsynth for example). Just tested with one song, but it seems working. Thanks a lot my friend. Have a nice day.
