Electronic musical instrument with keyboard

Claim 2

An electronic keyboard musical instrument comprising: a keyboard having a plurality of multifunction performance keys; memory means coupled to said keyboard and including means for previously storing a single series of note codes; control means including function setting means for setting a function for predetermined multifunction performance keys on said keyboard as note code reading instruction keys for enabling reproducing of tones of the note codes previously stored in said memory means upon operation of said keys set as said note code reading instrumentation keys; and means coupled to said control means for setting different volume levels to reproduced tones as a function of the arrangement of the performance keys set as said tone code reading instruction keys.

Claim 3

An electronic keyboard musical instrument according to claim 1, wherein said memory means is connected to previously memorize a series of musical note codes obtained through operations of a plurality of performance keys on said keyboard.

Claim 4

An electronic keyboard musical instrument according to claim 1, comprising external input means coupled to said memory means to supply and previously store in said memory means a series of musical note codes from said external input means.

Claim 5

An electronic keyboard musical instrument according to claim 1, wherein said function setting means includes a function changing switch having a normal performance position and a readout/performance position and wherein, when said function changing switch is positioned at said normal performance position, said performance keys of said keyboard are adapted for a normal performance, and when said function changing switch is positioned at said readout/performance position, said plurality of performance keys are adapted for use as reading instruction keys of note codes previously stored in said memory means.

Claim 6

An electronic keyboard musical instrument according to claim 4, wherein said function changing switch further includes a keyboard division position, and said instrument further comprises: division code memory means for memorizing a note code of an operated performance key when said function changing switch is set at said keyboard division position; means for controlling the function of the operated performance keys to be set as normal performance keys or to be set as note code reading instruction keys when said function changing switch is at said readout/performance position; and said control means includes means for delivering a volume control signal in response to an operated performance key, when the operated performance key is set as a note code reading instruction key.

Claim 7

An electronic keyboard musical instrument according to claim 1, which further comprises: means for producing a first tone signal according to a note code previously stored in said memory means; means for producing a second tone signal according to the operation of a performance key in relation to said first one signal; and means for producing sounds corresponding to said first and second tone signals with the sound corresponding to said first tone signal under volume level control by said volume level setting means.

Claim 8

An electronic keyboard musical instrument comprising: a keyboard having a plurality of multifunction performance keys; memory means coupled to said keyboard and including means for previously storing a single series of note codes; and means coupled to said memory means for recalling previously stored note codes from said memory means responsive to operation of different performance keys, said different performance keys designating different volume levels when tones are reproduced from said singles series of note codes.

Claim 9

An electronic keyboard musical instrument comprising: a keyboard having a plurality of multifunction performance keys; memory means coupled to said keyboard and including means for previously storing a single series of note codes; and means coupled to said memory means for recalling previously stored note codes from said memory means responsive to operation of different performance keys, said different performance keys designating different volume levels when tones are reproduced from said singles series of note codes.

Claim 10

An electronic keyboard musical instrument according to claim 7, further comprising function setting means for selectively setting said instrument to a normal playing mode or a readout/performance mode, said performance keys on said keyboard being used for a normal performance when said normal playing mode is set, and said different performance keys being used as reading instruction keys of the note codes previously stored in said memory means when said readout/performance mode is set.

Claim 11

An electronic keyboard musical instrument according to claim 8, comprising means for dividing said performance keys on said keyboard into two key groups responsive to said readout/performance mode being set, keys of one key group being set as normal performance keys, and keys of the other key group being set as said different performance keys for reading out the note codes previously stored in said memory means (30) and to reproduce the tones having different volume levels.

Claim 12

An electronic keyboard musical instrument according to claim 9, wherein in a keyboard division mode said plurality of performance keys are divided into said two key groups with any arbitrary note as a boundary, said arbitrary note being designated by a performer; and in said readout/performance mode a musical performance may be carried by the performance keys of said two key groups.
