Claim 8

An automatic playing apparatus, having an autoplay function, comprising: memory means for storing musical data of a musical piece to be played; musical tone signal generating means for generating musical tone signals in response to applied musical data; readout means responsive to application of a clock signal for reading out the musical data from said memory means in synchronism with the tempo of the musical piece, and for feeding the readout data to said musical tone signal generating means for autoplay of the musical piece; and repeat play means, coupled to said readout means and responsive to the readout of the last musical data for detecting the timing of the first beat of a bar after the readout of the last musical tone data and for restarting autoplay of the musical piece at the timing of the first beat.

Claim 9

The automatic playing apparatus according to claim 5, wherein said repeat play means is arranged to restart autoplay in synchronism with the timing of the first beat of a bar after the lapse of a time interval longer than one bar but shorter than two bars from the readout of musical data representing the last tone of the musical piece.

Claim 10

An electronic musical instrument, having autoplay function, comprising: memory means for storing musical data of a musical piece to be played; musical tone signal generating means for generating musical tone signals in response to applied musical data; autoplay designating means operable to set said electronic musical instrument to an autoplay mode so that the musical data in said memory means is read out from a start address and supplied to said musical tone signal generating means for autoplay of the musical piece; repeat play designating means, operable while said electronic musical instrument is in the autoplay mode, to set said electronic musical instrument to a repeat play mode for repetitive autoplay of the musical piece; clock signal generating means for generating a clock signal synchronized with the tempo of the musical piece; and control means for performing an operation comprising the steps of: reading out, in the autoplay mode, the musical data from said memory means in response to the clock signal and in synchronism with the tempo of the musical piece to feed the readout musical data to said musical signal generating means for autoplay of the musical piece; repeatedly counting the number of beats in at least one bar of the musical piece by counting the clock signal in response to said repeat play designating means; detecting the readout of musical data representing the last tone of the musical piece being played, in response to the operation of said repeat designating means; and detecting, in response to the detection of the readout of the last tone data and counting of the clock signal, the timing of the first beat in a bar after the readout of the last musical data, and reading the musical data out of said memory means from the start address at the timing of the first beat in the bar to repeat autoplay of the musical piece.
