Or in Garageband? I know my Yamaha GO46 audio interface works but i cannot get my concertmate 1500 to sound through on Logic. On Garageband I tried everything in the manual and I did see that it recognized that there was a MIDI device hooked up but nothing worked. I'm wondering if I have something wrong on the keyboard side..?Maybe I have to assign from the keyboard the MIDI to be sent out? Any help would be great. Thanks,Edd
