AB  - The control of frequency and duration independently of each other is accomplished by means of a rotary tape head. The history and principle of this device are reviewed, as are the various apparatuses employing it. The Audulator, the most recent of such devices, uses a keyboard to alter pitch over 24 chromatic steps without altering duration. The relationship of the musical scale to relative tape speed is discussed.
