Electronic instrument with a pitch data delay function

Claim 2

An electronic musical instrument, comprising: a plurality of pitch designation means for designating a pitch of a musical tone to be generated according to combined pitch-setting operations by a player; air flow sensor means for detecting an air flow state induced by a player and for producing a corresponding air flow sensing signal; tone generation instructing means for instructing generation of a musical tone at a pitch set by said plurality of pitch designation means based on said air flow sense signal produced by said air flow sensor means; change timing detection means responsive to a change in a combined pitch-setting operation of said plurality of pitch designation means, for detecting a timing of said change; and tone control means responsive to said change timing detection means detecting a change in said combined pitch-setting operation, for controlling generation of a musical tone at a new pitch newly set by said change in said combined pitch-setting operation, upon elapse of a predetermined time from said detected timing of said change.

Claim 3

The instrument according to claim 1, wherein said tone control means includes means for, upon detection of said timing of said change by said change timing detection means, generating a musical tone at a pitch according to pitch data corresponding to a pitch set prior to a change in said combined pitch setting operation until a predetermined time elapses from said detected timing of said change, and for generating a musical tone at a pitch according to pitch data corresponding to a pitch newly set after said change in said combined pitch setting operation after said combined predetermined time elapses.

Claim 4

The instrument according to claim 1, wherein said tone control means includes counter means for, upon detection of said timing of said change by said change timing detection means, starting a count operation and permitting output of pitch data corresponding to a pitch newly set by said pitch designation means when a predetermined count value is reached.

Claim 5

The instrument according to claim 1, further comprising tone generating means for, when a combined pitch-setting operation of said plurality of pitch designation means is executed, generating a musical tone at a pitch set by said pitch-setting operation.

Claim 6

The instrument according to claim 1, wherein said plurality of pitch designation means include: a plurality of first pitch designation means for setting a pitch of a musical tone to be generated by a unit of a half tone or a whole tone; and at least one second pitch designation means for altering said pitch set by said first pitch designation means by a unit of an octave and setting said altered pitch; wherein said change timing detection means includes first and second change timing detectors for independently detecting changes in pitch setting operations of said first and second pitch designation means; and wherein said tone control means includes pitch data output means for, when timings of said changes are detected by said first and second change timing detectors, outputting pitch data corresponding to new pitches set after said changes in said pitch setting operations occur, upon elapse of predetermined first and second times from said timings of said changes, respectively.

Claim 7

The instrument according to claim 5, wherein said pitch data output means includes time setting means for arbitrarily setting said first and second times.

Claim 8

The instrument according to claim 5, wherein said first and second times have a same duration.

Claim 9

The instrument according to claim 5, wherein said duration of said second time is longer than a duration of said first time.

Claim 10

The instrument according to claim 1, further comprising elapse time setting means capable of variably setting a duration of said predetermined time to an arbitrary value.

Claim 11

An electronic musical instrument, comprising: air flow sensor means for detecting an air flow induced by a player and for producing a corresponding air flow sense signal; tone generation instructing means for instructing a start of generation of a musical tone at a pitch set by said plurality of pitch designation means when said air flow sense signal produced by said air flow sensor means reaches a predetermined level or is above said predetermined level; tone generation keeping means for controlling continuous generation of a musical tone at said pitch set by said plurality of pitch designation means after said tone generation instructing means instructs said generation of said musical tone, and until said air flow sense signal reaches a predetermined level or is below said predetermined level; change timing detection means for detecting a timing of a change in a combined pitch setting operation of said plurality of pitch designation means; and pitch altering means responsive to said change timing detection means detecting a timing of a change in said combined pitch setting operation while tone generation continues based on said air flow sense signal from said air flow sensor means, for outputting pitch data corresponding to a pitch newly set by said change in said combined pitch setting operation upon elapse of a predetermined time from said timing of said change in said pitch setting operation, and for altering an old pitch set at said timing of said change in said pitch setting operation to a new pitch according to said newly outputted new pitch data.

Claim 12

An electronic musical instrument, comprising: air flow sensor means for detecting an air flow induced by a player and for producing a corresponding air flow sense signal; tone generation instructing means for instructing a start of generation of a musical tone at a pitch set by said plurality of pitch designation means when said air flow sense signal produced by said air flow sensor means reaches a predetermined level or is above said predetermined level; tone generation keeping means for controlling continuous generation of a musical tone at said pitch set by said plurality of pitch designation means after said tone generation instructing means instructs said generation of said musical tone, and until said air flow sense signal reaches a predetermined level or is below said predetermined level; change timing detection means for detecting a timing of a change in a combined pitch setting operation of said plurality of pitch designation means; and pitch altering means responsive to said change timing detection means detecting a timing of a change in said combined pitch setting operation while tone generation continues based on said air flow sense signal from said air flow sensor means, for outputting pitch data corresponding to a pitch newly set by said change in said combined pitch setting operation upon elapse of a predetermined time from said timing of said change in said pitch setting operation, and for altering an old pitch set at said timing of said change in said pitch setting operation to a new pitch according to said newly outputted new pitch data.

Claim 13

The instrument according to claim 10, wherein said pitch altering means includes means for, upon detection of a timing of a change in said pitch setting operation by said change timing detection means, altering a pitch to a pitch newly set upon elapse of a predetermined time from said timing of said change.
