It is definitive the branch 0.8.x has been created about 2 weeks ago. It is actively developed, now. The release 1.0 has been delayed thereof.

Improved MIDI work-flow

The AgsMidiBuilder object has been fixed and added unit tests to ensure it is operating correctly. There were some problems with missing delta-time argument on the closures. Further some other issue are fixed related to Standard MIDI Files. Like repeating channel-messages.

Import/Export to Standard MIDI File

So far the import and export wizards are implemented and functional. But it has a need to be clarified how default duration of notes shall be interpreted.

Since the lowest resolution of MIDI is about 32 ticks. Whereas GSequencer user interface only shows 16 ticks. However you may want to adjust segmentation likewise in the MIDI time signature.

The tempo is interpreted correct. As you import MIDI files there seems something wrong with start offset. You may cut and paste to find offset.

This issue shall be fixed in order to be qualified for release.

Improving MIDI playback

Another issue is MIDI playback and shall be improved, too. The work will be scheduled for following release numbers. That means it is not a must criteria in order of the 0.8.0 release.

The release is expected within few days.
