A foot percussion device can include a rigid board defining an upper surface and a lower surface distal from the upper surface; a spacer secured to and extending from the lower surface of the board, the spacer being compressible and defining a height before compression, the spacer configured to isolate the board from contact with a floor surface on which the device is placed; an audio jack; and a sensor in contact with and secured to one of the upper surface and the lower surface of the board, the sensor configured to convert mechanical vibrations in the board to electrical signals transmittable through the audio jack.

A system and method for interfacing and controlling multiple musical instrument effects modules on a common platform. The system includes: a system processor; a backplane coupled with the system processor; a plurality of musical instrument effects modules removably inserted into the backplane, each of the plurality of musical instrument effects modules including an audio input signal interface and an audio output signal interface, at least one of the musical instrument effects modules including a programmable potentiometer and/or programmable switch to modify an audio output signal; and a user interface configured to enable a user to apply a desired setting on the programmable potentiometer of the musical instrument effects modules via the system processor and the backplane.

A pedal device for an electronic percussion instrument is provided, wherein first and second detection means for detecting a rotation of a pedal by different methods are alternatively disposed in a base. The pedal has a pressing part on a lower surface side. The base includes a first portion located under the pressing part for supporting the first detection means, and a second portion located around the first portion for supporting the second detection means. The first portion supports the first detection means such that a first pressed part of the first detection means is disposed on a displacement trajectory of the pressing part that displaces with the rotation of the pedal, and the second portion disposes the second detection means such that a second pressed part of the second detection means is disposed on the displacement trajectory of the pressing part.

A pedal sound modification device is disclosed for varying an electrical signal. The device includes a plate pivotably coupled to a base. A slide potentiometer is coupled to the base and has a slider arm slidably engaging a linear potentiometer. The linear potentiometer extends between proximal slide end and a distal slide end. A linkage rod is pivotably coupled to the plate and the slide potentiometer for displacing the slide arm relative to the linear potentiometer upon a pivoting displacement of the plate relative to the base. The plate contacts the base for defining a proximal slide arm stop and positions the slide arm immediately adjacent to the proximal slide end for preventing damage to the slide potentiometer. The plate contacts the base for defining a distal slide arm stop and positions the slide arm immediately adjacent to the distal slide end for preventing damage to the slide potentiometer.

A sound production control apparatus by which a sound production mode is controlled on the basis of a player's motion even during a non-playing control operation period. An information obtaining unit 30 obtains detection information by detecting a player's motion. A sound processing unit 36 produces sound on the basis of the detection information obtained in response to operation for generating a sound trigger in the player's motion, and controls a sound production mode on the basis of the detection information obtained in response to operation for generating no sound trigger in the player's motion.

An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

A performance analysis method is realized by a computer and includes acquiring a time series of input data representing played pitch that is played, inputting the acquired time series of input data into an estimation model that has learned a relationship between a plurality of items of training input data representing pitch and a plurality of items of training output data representing an acoustic effect to be added to sound having the pitch, and generating a time series of output data for controlling an acoustic effect to be added to sound having the played pitch represented by the acquired time series of input data.

A musical performance system includes an instrument and a term1nal. Terminal includes a processor. Processor executes outputting first track data or first pattern data obtained by arbitrarily combining pieces of track data. Processor executes automatically outputting second track data or second pattern data obtained by arbitrarily combining pieces of track data. Instrument includes a processor. Processor executes acquiring first track/pattern data from terminal. Processor executes generating a sound of a music composition in accordance with first track/pattern data. Processor executes acquiring second track/pattern data from terminal. Processor executes generating a sound of a music composition in accordance with second track/pattern data.

An input musical sound signal is input to band pass filters, and pass musical sound signals for each sound pitch are acquired. Total level ratios based on a total of levels of a sound pitch lower than those of the pass musical sound signals are calculated from the levels that are levels of the pass musical sound signals, and output coefficients are acquired on the basis of the total level ratios. Levels of octave musical sound signals acquired by converting the pass musical sound signals into sound pitches lower than those of the pass musical sound signals by one octave are multiplied by the output coefficients. In accordance with this, the octave musical sound signals of a low sound pitch can be extracted from among the octave musical sound signals.

A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.
