The invention is recorded information reproducing device suitable for use in a kara-oke device and the like which reproduces sound information recorded on an information recording medium such as a CD (Compact Disk), LVD (laser Video Disk) or the like according to the MIDI (Musical Instrument Digital Interface) standards, and which also allows repeated practice in synchronization with the progress of music in kara-oke and the like. The recorded information reproducing device which reproduces sound from an information recording medium M on which encoded musical information AI and control information CI are recorded according to the MIDI standards. The recorded information reproducing device 100 includes a musical information reproduction unit for decoding the musical information to output reproduced musical information S.sub.A ; a control information reproduction unit for decoding the control information to output a clock signal S.sub.C for timing control; and a control means, in accordance with the clock signal S.sub.C, for controlling the sequence of reproduction of the music information in the music information reproduction unit 101 or a data storage means 103B, in accordance with the clock signal S.sub.C, for temporarily storing the reproduced musical information S.sub.A before it is output.

A MIDI apparatus and a MIDI system wherein an operation ON signal for starting operation to a MIDI instrument and an operation OFF signal for stopping the operation are obtained and supplied to the MIDI instrument in response to a MIDI format signal included in a subcode signal generated during play of a record medium play apparatus. If the play state of the record medium play apparatus becomes discontinuous, such as a pause after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal is obtained, the operation OFF signal is forcedly supplied to the MIDI instrument. Thereby such the sound of the MIDI instrument is stopped when there is a discontinuous play state after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal would ordinarily be supplied.

An output memory circuit device for and method of providing protection to an integrity of data stored in an external memory circuits during an output operation utilizing the data. Control means selectively controls activation of an external memory to an active state and an inactive back-up state, and obtains data from the external memory circuit during times corresponding to the active state. Storage circuit receives and temporarily stores data supplied by the control circuit and processing circuit receives and processes data fed from the storage circuit and outputs processed data to an output circuit. The control circuit selectively controls an activation of the external memory circuit to the inactive back-up state during times when receiving and processing is conducted to receive and process data fed from the storage circuit and output processed data to the output circuit.
