<p>PURPOSE:To repeat the performance with desired frequencies with an easy operation, by proceeding to the next program after repeating the performance via an IC chip which is controlled by a microcomputer in response to the set frequency. CONSTITUTION:A repeat switch of a key matrix KM is operated in a play mode with a frequency of operations in response to the repeating frequencies. Thus the repeating frequency is set. Then the process control is carried out via an IC1 of an IC forming a 1-chip microcomputer for the control 1-chip ICIC2-IC3 for a display reel motor MOT1, a capstan heater motor MOT2, etc. When an end interval of the music is detected, a tape is rewound fast. When the head interval of the music is detected, the tape is played forward. A set frequency counter is counted down with every repeat of the music performance. Then the next program is automatically played when the counter counts O. Thus the performance is repeated easily with desired frequencies just by setting a desired repeating frequency.</p> |
