This relatively small system would make set up and tear down quite simple but still give me everything I need except the large analog synths which would be a nightmare to transport. I'd sample all the modular and larger analog synth sounds needed and play them back from the Mediastation and Abacus. I could also use video playback from the MS to add background themes and scenes synced with the music. The Fairlight would allow me to do automated mixes live as well as add background tracks for more complex songs.
