Midi Instruments In Logic Express Options

[TheSalmonRiver]

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.)
