I am currently running a Yamaha S08 keyboard to Logic 9. I have my keyboard hooked up to my MAC Pro via a USB connection. When I use Garageband, the keyboard works so I know that my drivers are current and it recognizes my keyboard. However, when I am in Logic 9, I have set my channels up and it recognizes my board however, when setting up my auxiliary strip, I get no output (sound). I confess I am really new to this and it is probably something simple I am missing. I figure if my keyboard is working in Garageband (hearing the sounds) it should work in Logic 9. Please help! Thanks.
