Hi I'm new to Logic and I have a Roland Juno D keyboard hooked up to Logic pro 9 via Roland UM-1G midi-usb interface. I want to use the Roland keyboard as a midi controller to control the software instruments in the arrange window. I know that Logic is recognizing the interface because I can see "UM-1G" showing up in the Physical Input in the Clicks and Ports section of the Environment. However when I select a software instrument in the arrange window and press the keys on the Roland nothing happens. What am I missing??
