Apple Logic Pro /LogicExpress Discussion

hey,

    I recorded a project for a friend.  We used the Logic upright bass.  We're pretty happy with it.  But I'd like to A-B the sound with the Trilogy upright bass.

     Could I send you the MIDI file and ask  you to convert it to the Trilogy audio?

     I've got  EZDrummer, and Stylus RMX.  If I could exchange a similar sonic favor, that would be totally cool.

     Thanks!!

            Pete
