Midi Keyboards Freeze / Stuck / Hang in Both GarageBand and Logic

I had this problem, too, when I installed Sonoma 14.2.1. I accidentally fixed it by Muting two other Audio devices I thought might be conflicting.

The culprit was Microsoft Teams Audio Device used for MSTeams video meetings. Despite deleting the app for MSTeams, the audio device remained.

In Audio MIDI Setup, just try clicking the Mute checkbox on any audio device you don't need to use at the time. That's what worked for me. Worth a try. Hope it works for you, too.

Hello aaronmark,

Thanks for posting in the Apple Support Communities.

First, make sure that the macOS is fully up to date. If there were supplemental updates released, be sure those have been installed since many times they will contain fixes for issues you might experience in earlier macOS releases.

Update macOS on Mac - Apple Support

You'll also want to double check the MIDI keyboards you have are compatible with macOS Ventura and if there are any firmware updates for these devices, they have been installed. If you continue to experience issues, connecting with the support team for your MIDI keyboards would be best.

Best regards.

Hey aaronmark,

Your keyboard working some months ago, has no baring on their ability to work now on newer software. Seeing as how these keyboards aren't made by Apple and since Apple doesn't develop the software for them either, the manufacturer is best equipped to assist you from here if you're having issues using them on macOS Ventura.

Take care!
