A keyless synthesizer t can stimulate all three senses (hearing, muscle movement and visual) at once in patients born with C.H.A.R.G.E. syndrome while they play and, at the same time, enjoy and have fun with the device. A keyless synthesizer operational by a single hand of the user includes an ultrasound range sensor responsive to the distance d of a user's hand from the sensor for generating a sensor signal corresponding to the distance d. A programmable microcontroller programmed to convert the sensor signal to one of a plurality of discrete signals. A synthesizer is responsive to each discrete signal for generating a discrete tone. A multi-color generator is responsive to each discrete signal for generating a discrete color so that for each discrete signal corresponding to a distance d both a discreet tone and an associated discreet color are generated.

An electronic acoustic apparatus includes a control operator, a storage medium, and a processor. The control operator is operable by a user. The storage medium stores a program. The processor is configured to adjust a predetermined control parameter of an audio signal in response to an operation of the control operator. The processor is also configured to determine that the control operator has been operated in a particular operation style different from a normal operation style that adjusts the predetermined control parameter. In response to the operation of the control operator in the particular operation style, the processor is also configured to issue an instruction to execute a predetermined function different from an adjustment of the predetermined control parameter.

An keytar (1) includes a keyboard (2) on which a plurality of keys (2a) are arranged, a ribbon (5) in which a front surface panel (81) is arranged, and the degree of the same type of musical sound effect applied to each of tones (A-D) produced by the key (2a) is changed corresponding to detection positions in an X-direction in the front surface panel (81). Accordingly, because the degrees of the musical sound effects can be respectively changed for each of the tones (A-D) corresponding to the detection positions in the X-direction of the front surface panel (81), for the change of the same type of musical sound effect toward the tones (A-D), the monotony of this change can be suppressed and an expressive performance can be achieved.

Motion control data is received from one or more sensors. A first parameter value associated with a music composition is received from a digital audio workstation. A second parameter value associated with the music composition is received from the digital audio workstation. The motion control data is converted to one or more manipulations of one or more virtual objects. The one or more manipulations of the one or more virtual objects are mapped to at least a first command that adjusts the first parameter value and a second command that adjusts the second parameter value. The first command is sent to the digital audio workstation using a first audio input protocol recognized by the digital audio workstation. The second command is sent to the digital audio workstation using a second audio input protocol recognized by the digital audio workstation.

A controller, method, system, and computer-readable medium, for producing control signals. The controller comprises a pressure sensor, a hinged input mechanism configured to receive input forces and direct them towards the sensor, and a processor. The processor is configured to receive a signal from the pressure sensor indicating that the hinged input mechanism is being depressed or released and, based on the received signal, to determine, during a time interval, a rate of change of pressure detected at the sensor. The processor also generates a control signal associated with the hinged input mechanism, wherein the control signal comprises a velocity characteristic representing a speed at which the hinged input mechanism is depressed or released, and the velocity characteristic is based at least partly on the determined rate of change of pressure. In one example embodiment, the control signal is an audio control.

A method for producing and streaming music generated from biofeedback. The method employs machine-readable language instructions that alter received signals from a wearable biofeedback device, generating musical tones to be played on a portable electronic device and/or shared with others. The varying musical tones that are produced by the method can be modulated by the user to reach a targeted state of emotion.
