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.

A sound signal generation device comprises a first signal generation instructor and a second signal generation instructor. The first signal generation instructor provides an instruction for generating a key depression sound signal corresponding to a key depression at the time of the key depression based on key operation information corresponding to an operation of each key of a keyboard. The second signal generation instructor provides an instruction for generating a key release sound signal according to a manner of a key release at the time of the key release based on the key operation information.

A device is provided for capturing vibrations produced by an object such as a musical instrument such as a cymbal of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

Trigger devices, systems, and methods for sensing a strike on a vibratory membrane. A trigger device includes an optical sensor positioned a distance from the vibratory membrane and a processing device. The optical sensor includes an emitter that emits modulated light towards the vibratory membrane and a receiver that receives the modulated light that has reflected off the vibratory membrane and generates an electrical signal corresponding to the received modulated light. The electrical signal includes a peak corresponding to a detected strike on the vibratory membrane. The processing device isolates the peak from the electrical signal and generates one or more of a signal and data corresponding to the electrical signal.
