Electronic musical instrument

An electronic musical instrument comprising:

• an input device for inputting performing information that instructs generation or silencing of a tone with a predetermined pitch;
• a tone generation device that generates or silences a tone with a predetermined pitch based on performance information inputted by the input device;
• a hold device that, when a silencing of a tone being generated by the tone generation device is instructed by performance information inputted by the input device, withholds a silencing control to hold the tone being generated;
• a judging device that, when a predetermined number or more of tones are held by the hold device, judges as to whether or not there are tones held having a pitch difference within a predetermined value with respect to a tone instructed to be generated by performance information inputted in the input device;
• and
• a silencing control device that, when the judging device judges that there are tones held having a pitch difference within the predetermined value with respect to the tone instructed to be generated, performs a silencing control on one of the tones held having the pitch difference within the predetermined value and, when the judging device judges that there is no tone held having a pitch difference within the predetermined value with respect to the tone instructed to be generated, performs a silencing control on one of the tones held.

An electronic musical instrument, comprising:

• an input device;
• a sound source;
• a hold device;
• a processor;
• a memory device;
• and
• a computer storage device including a program executed by the processor to perform operations, the operations comprising:
• indicating in the memory device held notes having pitches as held in response to receiving note-on information for the held notes from the input device while receiving hold information from the hold device;
• causing the sound source to generate the pitches for the held notes;
• receiving from the input device note-on information for a received note having a pitch while generating the pitches for the held notes;
• determining whether a pitch difference of the pitch of the received note and at least one of the pitches of the held notes is less than a predetermined number of tones;
• selecting one of the held notes to release according to a first selection criteria in response to determining that the pitch difference of the received note and at least one of the held notes does not exceed the predetermined number of tones;
• and
• selecting one of the held notes to release according to a second selection criteria in response to determining that the pitch difference of the received note and the at least one of the held notes exceeds the predetermined number of tones, wherein the first criteria and the second criteria select different of the held notes to release;
• and
• causing the sound source to silence the generating of the selected one of the notes.

A computer storage device including a program executed by a processor to perform operations with respect to an electronic musical instrument having an input device, a sound source, a hold device, and a memory device, wherein the operations comprise:

• indicating in the memory device held notes having pitches as held in response to receiving note-on information for the held notes from the input device while receiving hold information from the hold device;
• causing the sound source to generate the pitches for the held notes;
• receiving from the input device note-on information for a received note having a pitch while generating the pitches for the held notes;
• determining whether a pitch difference of the pitch of the received note and at least one of the pitches of the held notes is less than a predetermined number of tones;
• selecting one of the held notes to release according to a first selection criteria in response to determining that the pitch difference of the received note and at least one of the held notes does not exceed the predetermined number of tones;
• and
• selecting one of the held notes to release according to a second selection criteria in response to determining that the pitch difference of the received note and the at least one of the held notes exceeds the predetermined number of tones, wherein the first criteria and the second criteria select different of the held notes to release;
• and
• causing the sound source to silence the generating of the selected one of the notes.

A method, comprising

• indicating in a memory device held notes having pitches as held in response to receiving note-on information for the held notes from an input device of an electronic musical instrument while receiving hold information from a hold device of the electronic musical instrument;
• causing a sound source of the electronic musical instrument to generate the pitches for the held notes;
• receiving from the input device note-on information for a received note having a pitch while generating the pitches for the held notes;
• determining whether a pitch difference of the pitch of the received note and at least one of the pitches of the held notes is less than a predetermined number of tones;
• selecting one of the held notes to release according to a first selection criteria in response to determining that the pitch difference of the received note and at least one of the held notes does not exceed the predetermined number of tones;
• and
• selecting one of the held notes to release according to a second selection criteria in response to determining that the pitch difference of the received note and the at least one of the held notes exceeds the predetermined number of tones, wherein the first criteria and the second criteria select different of the held notes to release;
• and
• causing the sound source to silence the generating of the selected one of the notes.
