Electronic percussion instrument and recording medium with program recorded therein
First Claim
1. An electronic percussion instrument comprising:
- a stick; and
a main body section;
wherein the stick includes;
a detecting section which detects an acceleration and an angular speed based on movement of the stick;
a first timing generating section which generates a beat timing based on a predetermined tempo and beat width;
a first pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section;
a first judging section which judges whether or not the first pre-sound-production movement detecting section has detected the pre-sound-production movement between a predetermined amount of time before a preceding beat timing and a predetermined amount of time before a current beat timing; and
a transmitting section which transmits a pre-sound-production movement detection signal, when the first judging section judges that the pre-sound-production movement has been detected; and
wherein the main body section includes;
a receiving section which receives the pre-sound-production movement detection signal transmitted from the stick;
a second timing generating section which generates a beat timing based on a predetermined tempo and beat width; and
a sound production instructing section which instructs to produce a sound at the beat timing generated by the second timing generating section, when the receiving section receives the pre-sound-production movement detection signal.

Abstract
An electronic percussion instrument including: a detecting section which is provided in a stick and detects acceleration and angular speed based on movement of the stick; a first timing generating section which generates beat timing based on a predetermined tempo and beat width; a first pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section; and a sound production instructing section which instructs to produce a sound at the beat timing generated by the first timing generating section, when the first pre-sound-production movement detecting section detects the pre-sound-production movement.

3. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer in a stick and a computer in a main body section,
wherein the program is executable by the computer in the stick to perform functions comprising: -
detection processing for detecting an acceleration and an angular speed based on movement of the stick; first timing generation processing for generating a beat timing based on a predetermined tempo and beat width; first pre-sound-production movement detection processing for detecting a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected in the detection processing; first judgment processing for judging whether or not the pre-sound-production movement has been detected in the first pre-sound-production movement detection processing between a predetermined amount of time before a preceding beat timing and a predetermined amount of time before a current beat timing; and transmission processing for transmitting a pre-sound-production movement detection signal, when the pre-sound-production movement is judged to have been detected in the first judgment processing; and wherein the program is executable by the computer in the main body section to perform functions comprising; reception processing for receiving the pre-sound-production movement detection signal transmitted in the transmission processing; second timing generation processing for generating a beat timing based on a predetermined tempo and beat width; and sound production instruction processing for instructing to produce a sound at the beat timing generated in the second timing generation processing, when the pre-sound-production movement detection signal is received in the reception processing.
