I'm looking for more information on a music composition program by subLOGIC titled "Music Maker" along with its companion "Kaleidoscopic Maestro." The following link is a YouTube video capture of the Kaleidoscopic Maestro program in action:
Specifically, I'm wondering how to call machine language subroutines from the compiled music modules in Integer BASIC programs. A cursory inspection of the DEMO program (written in Applesoft) reveals BRUNing the module, then issuing a USR(X) function, where X is the song number. Somehow, this jumps to the machine language subroutine containing the song. I'm wondering if there's an equivalent CALL (I'm guessing) in Integer BASIC.
This title is in the Asimov disk image archive.
Anyway, I'd be forever thankful to whoever knows where to get the manual to this program. Thanks!
