I am using OS X 10.11 el capitan. Since there is no working driver for my USB-Interface (M-Audio Fast Track Pro) I uninstalled the driver to let my interface work as a class compliant device.
That works well. I can see the pitch in the OSX sound settings and can record in Quick Time and Adobe Audition. But when I want to use Logic the MIDI-Input just works fine but there is no input channel I can use for audio inputs (mic, guitar, etc).
Do you now any hints how to address the input channels in Logic correctly? I appreciate any answer.
