It seems the title is just: "Musical Applications of Microprocessors"

One of the better books on the topic of 'chip music' for me was Hal Chamberlin's "Musical Applications of Digital Microprocessors" [1]. What was more interesting to me was that I used his fixed point fractional scheduling algorithm to write an I/O scheduler for disks that would allow you to portion out I/O to different processes (or containers) by an arbitrary percentage of the disk channel's bandwidth.
