ABSTRACT:
A tape recorder has a starter knob which is depressed during playback to cause a first memory to store information pertaining to the start of a sequence of sounds which are to be reproduced again. When the knob is released, a second memory stores information pertaining to the end of the selected sequence and the motor of the tape recorder is set to rewind the corresponding portion of the tape, either automatically or on depression of a repeater knob. The information which is stored in the first memory serves to start the motor for playback when the rewinding of that length of tape which bears the selected sequence of sounds is completed, and the information in the second memory serves to initiate rewinding of tape upon completion of renewed reproduction of the selected sequence. The starter knob can be depressed again to change the length of the selected sequence of sounds. An off knob is depressed when the operator wishes to erase the information which is stored in the memories or to transfer information from the second memory into the first memory so that the next repetition cycle involves repeated reproduction of a sequence of sounds which immediately follows the previously selected sequence.
