Here's the result: A video which shows a workflow involving Orb Composer and Synfire.Can’t wait to see the results!
While Orb Composer can create music "out of thin air", Synfire is great at working with already analyzed material and refining harmonically and rhythmically intricate musical structures.
In the screencast Orb Composer creates a chord progression and a melody whereas Synfire analyzes the material Orb Composer delivers and gets it ready for further processing and re-using.
