BNO Acoustics XV-16: Pitch Control
Facility on some sound playback devices for changing the speed of playback, and thus the pitch or frequency of the sound, to match an existing sound, or to fit a particular timeslot. Some Professional CD players have tempo controls which speed up the playback, and then compensate for the resulting increase in frequency using a pitch change. This results in the ability to match the beat of a CD in a disco situation, without the "Pinky and Perky" effect.

BNO Acoustics XR-90: Cue

2) To set the tape or disc so that the intended selection will immediately play when the tape machine or player is started.
3) A location point entered into a computer controlling the playback or recording of a track or tape.
