I just tried to submit a MIDI file for my latest remix, Song of Praise, and I’m getting the following error:

There was error in the file format
Expecting “MTrk” at 47477, found instead
Unknown pseudo-format

I selected to add it as an Alternate File Format on the Manage Files page. (Related minor bug - Alternate is misspelled “Altnerate” in the dropdown). This is how I have successfully added MIDI files in the past, like on my Fishes in the Sea remix. Nothing has changed on my end except for perhaps a minor version update of my DAW software, so I’m not sure what happened.

Any help is appreciated!

So FYI to anyone else that hits this problem. I’ve worked around it in the meantime by just putting the MIDI file in a ZIP archive. System seems to take that just fine.
