Claim 7

A multi-recording apparatus of an electronic musical instrument comprising: (a) a plurality of input channels each inputting performance information, said performance information comprising event data representing events of depressed or released keys and generation timings of said events; (b) memory means for recording the inputted performance information for every input channel; (c) setting means for selectively permitting recording and reproducing of each input channel in said memory means, said setting means selectively setting one of a recording mode, a reproducing mode and a stop mode; (d) recording control means for reading first performance information from a first input channel which is permitted to be recorded in accordance with clock information pre-stored in said memory means, and for over-recording the read first performance information with newly inputted second performance information on said first input channel when said setting means sets said recording mode; (e) first output control means for selecting second performance information from a plurality of inputted performance information and outputting the selected second performance information to be recorded on said first input channel within said plurality of input channels in said recording mode; (f) second output control means for selecting third performance information from a plurality of performance information read from said memory means, the selected third performance information being outputted with respect to a second input channel which is permitted to be recorded or reproduced in said recording or reproducing mode; (g) a plurality of output channels; and (h) selecting means for selecting said output channel corresponding to said first or second input channel, said selecting means outputting said performance information of each input channel outputted from each of said first and second output control means to the selected output channel.

Claim 8

A multi-recording apparatus according to claim 5, wherein said inputted performance information is supplied from a keyboard of said electronic musical instrument.

Claim 9

A multi-recording apparatus according to claim 5, wherein said inputted performance information is supplied from a computer.

Claim 10

A multi-recording apparatus of an electronic musical instrument comprising: (a) memory means for recording event data as performance information, said event data representing events of depressed or released keys and generation timings of said events; (b) setting means for selectively setting one of a recording mode, a reproducing mode and a stop mode at least; (c) first storing means for storing first information representative of depressed states of keys which are designated by said performance data inputted from external performance means; (d) recording control means for recording the inputted performance information in said memory means in said recording mode, said recording control means detecting depressed keys based on contents of said first information stored in said first storing means so as to generate and record first releasing information of said depressed keys in said memory means when said recording mode is changed to said stop mode; (e) reading means for reading said performance data from said memory means; (f) second storing means for storing second information representative of the key depression states designated by the read performance information; and (g) output control means for outputting said read performance information in said recording and reproducing modes, said output control means detecting depressed keys based on contents of said second information stored in said second storing means so as to generate and output second releasing information of the depressed keys when said recording or reproducing mode is changed to said stop mode.

Claim 11

A multi-recording apparatus of an electronic musical instrument comprising: (a) memory means for recording event data as performance information, said event data representing events of depressed or released keys and generation timings of said events; (b) setting means for selectively setting one of a recording mode, a reproducing mode and a stop mode at least; (c) first storing means for storing first information representative of depressed states of keys which are designated by said performance data inputted from external performance means; (d) recording control means for recording the inputted performance information in said memory means in said recording mode, said recording control means detecting depressed keys based on contents of said first information stored in said first storing means so as to generate and record first releasing information of said depressed keys in said memory means when said recording mode is changed to said stop mode; (e) reading means for reading said performance data from said memory means; (f) second storing means for storing second information representative of the key depression states designated by the read performance information; and (g) output control means for outputting said read performance information in said recording and reproducing modes, said output control means detecting depressed keys based on contents of said second information stored in said second storing means so as to generate and output second releasing information of the depressed keys when said recording or reproducing mode is changed to said stop mode.
