Hammer : Your friend is using Deluxe Music 2 beyond its design goals. Deluxe Music 2 is designed to work with dedicated sequencer software such as Music-X(page 106)
One might even argue that Deluxe Music was a fun toy that basically was written at a time when exploiting the Amiga's onboard sound was pretty exciting stuff. It's NEVER been as useful as any entry-level musician-oriented MIDI tools or music scoring / printing tools. People who have an interest in this field simply graduate to applications that were actually designed for that. Which has usually meant working on another platform entirely - reason evident when you see a decent sequencer like Music-X having to rely on something like Deluxe Music for notation.
Programs like Deluxe Music (regardless of version) have always been a lot of fun, colorful, educational, and useful for occasional dabblers - and that was what they were designed to be. In that regard they met their design goals admirably.
