Mac OS 13 Ventura & Mac OS 14 Sanoma
both elk-herd and elk-herd beta
I have found a pretty nasty bug in Apple’s CoreMIDI USB implementation that strikes sending larger SysEx messages to the Digitakt.
The bug will manifest during saving a project back to the Digitakt (original or II).
What you’ll see is that some patterns and possible some sounds won’t make to the machine. Nothing will be corrupted, and any patterns or sounds that made it will not be corrupted. Just some might be missing.
Check your DT after you send a project back to the instrument and make sure everything is there. If not:
-
You can (should) save the project in elk-herd to a file, and this file will be complete.
-
Just send it again! The bug randomly breaks some messages, but not always the same ones… so sending a few times will usually get everything there.
-
Please DM me about this with whatever details you have. I want to understand how prevalent this issue is.
Mac OS 15 Sequoia appears to have fixed the issue, so if you can upgrade, here’s your reason.
Older systems: I’ve never seen this before OS 13… but hardly kept extensive tests on each Mac OS release… so if you are running an older Mac OS, please check for this bug and let me know if you see it or not.
THANKS ALL!
