Logic Pro 'No input source selected' alert halfway through recording
So I'm recording VO with Volt 276 interface. Everything is fine, then suddenly, NO INPUT SOURCE SELECTED. Am I doing something wrong? Ive checked my settings and input and output set to Volt 276 interface. It's been fine until yesterday, it happened once. I had to create a new project to keep working. Then it was fine. But it's just happened on the new project too. Any help would be greatly appreciated. I use Logic Pro a lot, but I'm still very new!
