When I play the midi instruments in L.E 7.1, I hear the sound of them through the speakers of my keyboard. If I try to make a song with a midi instrument, and exports it to iTunes, the midi instrument track is gone.

Is there a way to use the midi instruments?

(I think the sound of the midi instruments are the same as on my keyboard. The drums are excactly the same.)

1.) Midi does not make any sound.
2.) to hear outboard midi devices in logic the audio outputs must be connected to your audio interface
3.) Outboard midi gear must be recorded to an audio track.

Is there a simple way to "connect my audio outputs to the audio interface so I can hear the outboard midi devices in Logic? (I'm a Logic newbie"

Left and right outputs of the keyboard to input 1&2 of the interface, probably will be 1/4 inch connectors or RCA.

Thanks for the help
