I am close to completing this feature 👍 |
|
fixes:#4311 @pikurasa I think the PR is ready for review. Please check it. Next, I have to work on adding instruments to the MIDI file. After exporting, you can play the MIDI file in media players like Windows Media Player. Right now, it will only play on the piano. |
|
@pikurasa The midi export is finally done. Please review this PR. final.mp4For testing we can use : https://pianotify.com/import-midi-file |
|
I tested https://github.com/sugarlabs/musicblocks/blob/master/examples/Holly-Jolly-Christmas.html, and the output seems to get off track after the third note. This is the MIDI file generated while on your branch, |
|
@pikurasa, I have fixed the issue. I thought _midiData was filled instantly, but that is not the case. It takes some time to retrieve all the data. Like Lilypond and others, I have created an after-save function to generate a MIDI file when midi data is filled. Here is the result :-> midi2.mp4 |
|
Yes, it seems to work well. I think it's ready for a code review. |

Should this be Save music as MIDI ???

Yeah, I thought about that. You can edit MIDI files, so I thought "project" would be appropriate.
|
Also, since when you import MIDI, you get a MB project, I guess "project" does make sense. |
|
I can add test cases for MIDI now in SaveInterface |
|
@Commanderk3 Please add documentation for .MIDI export in |
Sure |
|
FWIW, I tested our "Romanian Folk Dance" example (in the examples folder), and I'm very impressed with how it was able to handle the complex rhythms in that project. |
|
Happy to see it working! |
