A program, MAESTRO, has been written for a small computer, allowing a person at the computer console to define and play up to nine different musical instruments.

Samples of the resulting pressure wave are written onto a digital magnetic tape which can be read through a digital-to-analog converter, under clock control, to produce the musical sound.
