I’m using LogicPro X on a MacBook, with a Presonus AudioBox USB 96 audio interface connected via USB, and a M-Audio Oxygen 49 MIDI keyboard also connected via USB.
Everything worked fine until this morning. Now, when I turn on the keyboard, the Presonus stops working and LogicPro gives the “last selected audio interface no longer available” error message.
For some reason, the two devices seem to be conflicting with each other. I don’t know what changed because everything worked together before.
Any suggestions how I might resolve this? Layman terminology would be appreciated as I’m relatively new to the DAW world. Thanks.
