Definitions

  • the main object of the present invention is, in the electronic instrument described above, to highly increase the recording density by intermittently driving the recording medium on which the keying patterns are recorded past a magnetic head through a predetermined distance only when the keying pattern varies.
  • FIG. 6 is a block diagram of the start pulse generator in FIG. 5.
  • FIG. 1 is a general block diagram which illustrates in broad schematic form a recording system for recording keying patterns of an electronic instrument on a recording medium such as the magnetic tape shown in FIG. 3.
  • a parallel-serial translating circuit 1 which is provided with as many input terminals as the number of keys of the electronic instrument, has the function of translating the groups of parallel signals, which are associated with the keying patterns and supplied to the input terminals, into serial pulse signals that shift in every one clock pulse time unit in accordance with the clock pulses supplied from a clock pulse generator 2.
  • the new keying pattern has already been stored as the (n+1 )th keying pattern in the serial-parallel translating circuit 6, and the motor M has already started to revolve. Consequently, the output signals of both the parallel-serial translating circuits 1 and 11 are sent out by the incoming clock pulses respectively, and recorded on the respective tracks of the magnetic tape at the same time. That is the keying pattern signal of the (n+1 )th block is recorded on a second track of the magnetic tape through the one bit delay circuit, the amplifier 4 and the magnetic head HR2; and the time count pulse signal associated with the keying pattern recorded on the (n)th block of the magnetic tape is recorded on a third track through the amplifier 12 and the magnetic head I-IR3.
  • a start pulse generating comparison circuit 21 operates to generate a start pulse (having, for example, one bit width) which opens a selective gate 22 so as to supply the clock input terminal of a shift register 23 with the clock pulse decoded by a decoder 24 from the output of a read-out magnetic head HPl.
  • the (n)th time count signal written in the (n+l )th block will be read-out through a magnetic head HP3 and, after being decoded by the decoder 28, will be shifted into the shift register 23 in accordance with the clock pulse from the decoder 24.
  • An automatic performance system for electronic 6 instruments comprising a source'of clock pulses; parallel-serial translating circuit means for translating groups of parallel ON-OFF signals generated in parallel in accordance with keying patterns of an electronic instrument, into a train of serial pulse signals that may .vary in every predetermined infinitesimal time unit corresponding to a clock pulse; a recording means including a recording head and a recording medium for intermittently driving said recording medium a predetermined distance relative to said recording head in response to a change in said keying pattern so that an output signal from the parallel serial translating circuit means is recorded in one block corresponding to said predetermined distance ofa track of the recording medium and so that the time duration of the block is recorded as time count signals in the succeeding block of another track of the recording medium; means for controlling the intermittent movement of the recording medium in accordance with the time count signal; a reproducing head for reproducing the intermittently recorded output from said parallel-serial translating circuit means; a serial-parallel translating circuit means for translating the recorded train of serial pulse signals, read out through said reproducing head
