After my first experiences with AY I tried compose music. I am music analphabet but composing in Soundtracker is so easy. I was used my musics composed in Orfeus (Czechoslovak beeper music editor by Unversum - 2 channels + drums, patterns, loops) to take less hits fighting with musas. As you will know from scroll this musics used to sounds in CAD demo. Unfortunately I was not able to play soundtracker routine in interrupt with CAD:basic routine.
