I have logic pro 9 and have attached a M audio interface which in turn is connected to a M audio buddy to record vocals and guitar, when i use it in Logic i get the mic but then my usb M audio keyboard does not work. I tried to revert to the macs own audio and although the keyboard works the internal mic does not. I am new to this and i think ive followed all the instructions properly but i cant figure it out at all. Any help would be appreciated.
