I’m having some odd issues with my UR22 on my iMac 5k. I’ve upgraded to the latest drivers for UR22, and updated the mac to the latest version, but when loading projects in Logic I’m getting various error messages.
The first, and most problematic of them all, is that I keep getting a logic error on opening saying error initialising coremidi, midi services unavailable (see screenshot). When I switch to built-in audio it’s fine, but it just won’t work with the UR22 for some reason. It’s not just in logic though, when I try to use spotify/soundcloud or youtube, or even quicktime (offline), no audio/video will play back. On youtube it buffers, but stays at 0:00 no matter what I do. As soon as I switch to built-in audio, rather than the UR22, it works fine again, switching back, playback stops.
The second problem is that I’m getting errors sometimes during playback saying ‘Error while trying to sync Audio and MIDI: Sample rate … not recognised’. I’ve got the project in Logic set to 44.1kHz.
Any advice? It’s seriously impacting my work!
