After downloading the Universal Control, my Mac still doesn't work with the Studio26c. Microphone and guitar signals go through but the GarageBand will not allow to adjust levels of the track. When clicking the apple-logo and Sound I again am not able to adjust levels (input or output) even though it recognizes that the Studio26c is plugged in. Only when in plug the Studio26c out, the levels are adjustable.
Terminology is not what it should be here, I know, but I hope you can help. Thanks.
