摘要： An automatic performance device is of a type in which the automatic performance is executed in accordance with musical data read out successively. It comprises a fast feed stop control circuit for advancing the progress of the automatic performance when an actual key depression timing is faster than an ideal key depression timing indicated by the read out musical data and for temporarily stopping the progress when the former delays behind the latter. Comparison between the actual key depression timing and the ideal key depression timing is made by comparing the content of a counter counting the tempo pulses which decides the tempo of the automatic performance with note-length information included in the musical data. It further comprises a tempo control circuit for changing a period of the tempo pulses based on a tempo of a performance made by the actual key depression. The detection of the tempo of the performance made by the actual key depression is based on a count value of a counter counting the clock pulses whose period varies with the note-length information and presence or absence of the actual key depression. In order to prevent the period of the tempo pulses from being changed by only one great deviation of the actual key depression timing, the count value is latched at every key depression, the newest count values are kept, and the tempo detection may be made in accordance with the average value of the newest count values.

摘要： An electronic musical instrument comprises a keyboard arranged to produce key code signals in response to key operations thereof and a memory storing performance data constituting progression of a music and corresponding to key operations to be effected on the keyboard to play the music. A key operation judging circuit is provided which compares the key code signals produced by the keyboard with the performance data read out of the memory to detect whether or not a pupil or trainee correctly operates keys in a corresponding relation to the performance data read out of the memory. The percentages of correct key operations are calculated and displayed with respect to the key-on timing and the pitch and duration of notes.

摘要： A tempo control device for automatic performance according to this invention is of a type wherein a tempo of automatic performance is caused to automatically follow that of manual performance as the latter changes during performance. When difference in tempo between manual and automatic performance falls within a predetermined range, this automatic follow-up control is performed by measuring the manual performance tempo with accuracy and by controlling the frequency of tempo clock pulses in the automatic performance on the basis of the value thus measured. The predetermined range may be one fixed range for all notes of various note-lengths, or alternatively, different ranges may be employed in accordance with the length of notes.

摘要： There are provided a transmission circuit capable of stabilizing high-speed data transfer by driving current, a data transfer control device, and electronic equipment. An HS current driver (transmission circuit) included in a data transfer control device has a current source connected between a first power supply AVDD and a node ND, and switching devices SW1 to SW3, one ends of which are connected to the node ND. The other end of the switching device SW1 is connected to a DP terminal. The other end of the switching device SW2 is connected to a DM terminal. The other end of the switching device SW3 is connected to a DA terminal. The DA terminal is connected to a second power supply AVSS inside or outside the transmission circuit. The transmission circuit is configured so that impedances of each current path from the node ND through the switching devices SW1 to SW3 become substantially equal when the switching device is turned on. This prevents an increase in the voltage of the node ND in a non-signal-transmission period.
