Wow, thanks for sharing that anecdote. That's the thing - many C64 musicians were also great programmers, especially to get the impressive sounds they wanted out of the SID.
Quote "If you wanted to be a videogame musician in the early 1980s, having a fantastic tune and even a Royal College of Music diploma meant nothing without some lateral thinking and a significant amount of programming skills, because the SID chip needed special software routines to turn its potential into sound. You had to know how to compose both melodies and machine code."
He was a programmer, but mainly did it to make money so he could make music... his real passion.
Funny guy...
