Abstract
Abstract A sound effect-creating device for imparting a sound effect to a musical tone produced by performance delays a musical tone signal of an analog or digital type by a predetermined delay time to repeatedly generate the musical tone. The predetermined delay time is set based on a basic delay time determined from the period of a timing clock of a MIDI signal received from an external electronic musical instrument. Alternatively, the period of a timing clock of a MIDI signal is determined from a basic delay time set for determining the predetermined delay time.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A sound effect-creating device for imparting a repeat effect to a musical tone produced by performance, including delay means for delaying a musical tone signal of analog or digital type by a predetermined delay time for repeatedly generating said musical tone, said sound effect-creating device comprising: MIDI signal-receiving means for receiving a MIDI signal for control of a musical instrument; basic delay time-calculating means for calculating a basic delay time based on a period of a timing clock of said MIDI signal received by said MIDI signal-receiving means; and delay time-setting means for setting said predetermined delay time based on said basic delay time calculated by said basic delay time-calculating means.
Claim 2
Dependent Claim
111 words
A sound effect-creating device for imparting a repeat effect to a musical tone produced by performance, including delay means for delaying a musical tone signal of analog or digital type by a predetermined delay time for repeatedly generating said musical tone, said sound effect-creating device comprising: MIDI signal-receiving means for receiving a MIDI signal for control of a musical instrument; basic delay time-calculating means for calculating a basic delay time based on a period of a timing clock of said MIDI signal received by said MIDI signal-receiving means; and delay time-setting means for setting said predetermined delay time based on said basic delay time calculated by said basic delay time-calculating means.
Claim 3
Dependent Claim
63 words
A sound effect-creating device according to claim 1, further including tempo determining means for determining a tempo of performance of said musical tone based on the period of the timing clock of said MIDI signal received by said MIDI signal-receiving means, and wherein said basic delay time-calculating means calculates said basic delay time based on said tempo determined by said tempo determining means.
Claim 4
Dependent Claim
53 words
A sound effect-creating device according to claim 1, wherein said delay time-setting means includes meter-setting means for setting a parameter indicative of a meter of said musical tone, and sets said predetermined delay time based on said basic delay time, and depending on said parameter indicative of said meter of said musical tone.
Claim 5
Dependent Claim
53 words
A sound effect-creating device according to claim 2, wherein said delay time-setting means includes meter-setting means for setting a parameter indicative of a meter of said musical tone, and sets said predetermined delay time based on said basic delay time, and depending on said parameter indicative of said meter of said musical tone.
Claim 6
Dependent Claim
106 words
A sound effect-creating device for imparting a repeat effect to a musical tone produced by performance, including delay means for delaying a musical tone signal of analog or digital type by a predetermined delay time for repeatedly generating said musical tone, said sound effect-creating device comprising: basic delay time-setting means for setting a basic delay time for use in setting said predetermined delay time; MIDI signal-delivering means for delivering a MIDI signal for control of a musical instrument; timing setting means for setting a period of a timing clock of said MIDI signal based on said basic delay time set by said basic delay time-setting means.
Claim 7
Dependent Claim
106 words
A sound effect-creating device for imparting a repeat effect to a musical tone produced by performance, including delay means for delaying a musical tone signal of analog or digital type by a predetermined delay time for repeatedly generating said musical tone, said sound effect-creating device comprising: basic delay time-setting means for setting a basic delay time for use in setting said predetermined delay time; MIDI signal-delivering means for delivering a MIDI signal for control of a musical instrument; timing setting means for setting a period of a timing clock of said MIDI signal based on said basic delay time set by said basic delay time-setting means.
Claim 8
Dependent Claim
44 words
A sound effect-creating device according to claim 5, wherein said basic delay time-setting means includes tempo determining means for determining a tempo of performance of said musical tone, and sets said basic delay time based on the tempo set by said tempo setting means.
Claim 9
Dependent Claim
56 words
A sound effect-creating device according to claim 6, wherein said delay time-setting means further includes meter-setting means for setting a parameter indicative of a meter of said musical tone, and sets said predetermined delay time based on said tempo set by said tempo setting means and said parameter indicative of said meter of said musical tone.
