A system for the controlled hitting of a percussion instrument such as a drum including an implement such as a bass drum pedal is described herein. The system comprises a controller for receiving a signal indicative of a beat and for sending triggering command, and an actuator for coupling to the implement and to the controller for receiving the triggering command from the controller and for causing the implement to move at the beat in response to a triggering command from the controller. According to an illustrative embodiment, the actuator includes a motor coupled to the controller so as to be controlled therefrom and a drive mechanism connected to the motor and to the implement for causing the motor to trigger the implement at the beat in response to the triggering command. The system is connected and controlled by a click through a MIDI connection.

The invention claimed is: 1. A system for the controlled hitting of a percussion instrument including an implement and an object capable of vibrations under controlled action thereon by the implement, the system comprising: a controller for receiving a signal indicative of a beat and for sending a triggering command; and an actuator for coupling to the implement and to the controller for receiving the triggering command from the controller and for causing the implement to move at the beat in response to the triggering command from the controller; the actuator including a motor coupled to the controller so as to be controlled therefrom, a drive mechanism connected to the motor and to the implement for causing the motor to trigger the implement at the beat in response to the triggering command and a mechanical coupler connected to both the drive mechanism and to the implement for coupling the system with the percussion instrument via the implement wherein the mechanical coupler is in the form of a rod to be secured to the implement; the rod including an L-shaped element mounted thereto for rotation in unison; the motor including a drive shaft provided with a projection in registry with the L-shaped element; the mechanical coupler being rotatably mounted coaxially to the drive shaft therein; whereby, in operation, bringing the implement in operative relation with the object capable of vibrations for the controlled action thereon while the implement is coupled to and actuated by the actuator causes the percussion instrument to vibrate at the beat, and a user pivoting the mechanical coupler results in the implement causing the percussion instrument to vibrate without preventing the rotation of the drive shaft. 2. A system as recited in claim 1, wherein the implement is a bass drum pedal. 3. A system as recited in claim 1, further comprising an impact detector coupled to the controller. 4. A system as recited in claim 3, wherein the impact detector includes timer electronic circuitry, an actuating switch connected to the timer electronic circuitry for actuating the timer electronic circuitry and a sensor coupled to the timer electronic circuitry for detecting the vibrations of the object under controlled action of the implement thereon; the timer electronic circuitry being for determining a triggering delay between the triggering command from the controller and a resulting triggered sound from the percussion instrument, thereby allowing the system to be calibrated for different position of the object capable of vibrations relatively to the implement and to the system. 5. A system as recited in claim 4, wherein the controller further includes a memory for storing a calibration signal indicative of a hit signature sound produced by a user on the percussion instrument; the controller being further configured to compare the resulting triggered sound to the hit signature sound. 6. A system as recited in claim 1, wherein, in the response to the triggering command from the controller, the actuator causes the implement to move at the beat with an intensity set by using the actuator to bias the implement towards the object capable of vibrations at a predetermined position relatively thereof prior to the beat. 7. A system as recited in claim 1, wherein the motor is a stepper motor. 8. A system as recited in claim 1, wherein the controller is configured for wireless or network communication so as to remotely receiving the signal indicative of a beat. 9. A system as recited in claim 1, wherein the object capable of vibrations is a drum or a cymbal.
