An electronic musical instrument according to one embodiment includes: a sound source configured to generate a first sound signal and a second sound signal in accordance with an instruction signal for instructing to produce a sound; a first output unit configured to output a third sound signal containing the first sound signal and the second sound signal at a first sound volume ratio; and a second output unit configured to output a fourth sound signal containing the first sound signal and the second sound signal at a second sound volume ratio that is different from the first sound volume ratio.

A sound source includes: a processor that implements instructions to execute a plurality of tasks, including: a first calculating task that calculates a first estimated value based on a detection result yielded by a detecting device that detects passage of a key through a first, a second, and a third positions, the first estimated value pertaining to behavior of the key at a predetermined position; a second calculating task that calculates a second estimated value based on the result, the second estimated value pertaining to behavior of the key at a fourth position; a signal generating task that generates a first and a second sound signals; a first adjusting task that adjusts an output level of the first sound signal based on the first estimated value; and a second adjusting task that adjusts an output level of the second sound signal based on the second estimated value.

A sensing system for a keyboard. Each key sensor comprises passive and active resonant circuits. The passive resonant circuit has a resonant frequency and the active resonant circuit excites the passive resonant circuit at the resonant frequency. A sensor driver drives the active resonant circuit with an RF drive signal, a multiplexing system multiplexes the drive signal such that simultaneously driven key sensors are separated by at least (k-1) keys, and a detector detects a level of RF signal from a driven key sensor for sensing a position and/or velocity of a key.

A signal generation method implemented by a computer system includes: generating an audio signal in response to a manipulation of each of a first key and a second key; and controlling generation of the audio signal based on a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key.

A handheld musical instrument for playing a variety of audio program, the handheld musical instrument comprising a body portion with one or more sensors and a handle portion coupled to said body part, wherein said handle portion includes one or more operational buttons to control the operation of said handheld musical instrument. The buttons being operated with a finger or thumb trigger.

A music generating system enables a user to generate independent and sequential musical melodies, having reduced latency periods, without playing an electronic percussion instrument. The music generating system includes an electronic percussion instrument, a MIDI controller coupled to the electronic percussion instrument, a unidirectional USB communication link coupled to the MIDI controller, a MIDI converter coupled to the unidirectional USB communication link, a bidirectional USB-MIDI communication link coupled to the MIDI converter, and a rhythm drum machine in communication with the bidirectional USB-MIDI communication link. The MIDI converter is configured to independently and sequentially receive and learn a first audio control signal and a second audio control signal in a non-overlapping pattern, and thereby independently and sequentially generates and transmits to the rhythm drum machine a first musical melody and a second musical melody corresponding to the first audio control signal and the second audio control signal, respectively.

A detection system detects a position of each of a plurality of movable members that are displaceable by a playing operation. The detection system includes a controller configured to generate a first signal with a signal that level discontinuously changes over time, a Pi filter configured to convert the first signal to a second signal with a signal level that continuously changes over time, and a signal processor configured to generate, using the second signal, an output signal that depends on a position of each of the plurality of movable members.

For each sound of a model performance, performance information designating a sound generation timing and sound are supplied, and for each of a plurality of phrases into which the model performance is divided, intensity information indicative of an intensity of sound for the phrase is supplied. In accordance with a progression of a performance time and for each phrase of the model performance, the intensity information is acquired ahead of a start timing when a performance of the phrase is to be started, and the intensity of sound common to sounds in the phrase is presented based on the acquired intensity information. The intensity of the sound is presented in a visual or audible manner. In this way, a human player can know, through a visual display and/or an audible sound, an intensity of a key depression operation for each phrase of the model performance before starting the phrase. As a result, the human player can practice the performance while being aware of the intensity of sound for each phrase.

A method for generating music is provided, the method comprising receiving, on a capacitive touch sensitive interface such as a keyboard, multi-finger gesture inputs having a first component and a second component, wherein the second component has a temporal evolution such as speed; determining the onset of an audio signal, such as a tone, based on the first component, analyzing the temporal evolution of the second component to determine MIDI or Open Sound Control OSC instructions; modifying the audio signal based on the instructions, in particular by decoupling the temporal relationship between specific gesture inputs (e.g. at key onset, during a note and upon key release), thus mapping gesture and motion inputs, to thus obtain previously unachievable musical effects with music synthesizers.

An improved musical instrument is disclosed. The musical instrument includes at least one key assembly and at least two sets of sensors. The sensors sense one or more attributes pertaining to a force exerted on the at least one key assembly. A control unit is provided to determine amount of force sensed by sensors based on the sensed one or more attributes, and to determine location, at which the force on the at least one key assembly is exerted based on the determined amount of force sensed by the sensors. The control unit is configured to generated signals based on the determined amount of force sensed by the sensors, and the determined location. The generated signals are associated with one or more acoustic parameters.
