Yep.  The music synthesis programs I wrote to play 4 or more part harmony out 
the Coco speaker used self-mod code to get reasonable speed.  As did a couple 
other ones I disassembled afterwards.  I'm just posting this so nobody will 
accuse Dennis of playing nasty copy-protection tricks with self-mod code.

I wrote a really neat combination of BASIC and machine code app (for RSDOS, 
not OS9) with a simple input language that the BASIC program compiled into 
binary code, which you could then save or play.  There was an instrument editor in 
BASIC too.  I showed it off at a Glenside meeting, and offered free copies, 
but I couldn't *give* it away.

I had better luck with UltiMusE, as did Lester Hands with Lyra.  I think the 
graphical approach to music writing goes over a LOT better, then and now.
