Systems, devices, media, and methods are presented for playing audio sounds, such as music, on a portable electronic device using a digital color image of a note matrix on a map. A computer vision engine, in an example implementation, includes a mapping module, a color detection module, and a music playback module. The camera captures a color image of the map, including a marker and a note matrix. Based on the color image, the computer vision engine detects a token color value associated with each field. Each token color value is associated with a sound sample from a specific musical instrument. A global state map is stored in memory, including the token color value and location of each field in the note matrix. The music playback module, for each column, in order, plays the notes associated with one or more the rows, using the corresponding sound sample, according to the global state map.

The user interface is designed to produce, when a zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . in a region 101, 102, . . . is activated, a musical tone-producing command in accordance with the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . and region 101, 102, . . . , and the musical tone-producing command comprises at least one basic chord note command of a pitch that is contained in the basic chord associated with the activated region 101, 102, . . . and comprises a tune note command the pitch of which corresponds to the musical tone of the tune of the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . . The invention also relates to a musical instrument, a method for producing combined sequences of chords and tunes, and a computer-readable storage medium.

A musical sound producing apparatus includes a plurality of keys, a sound production information generator that generates sound production information for producing a musical sound based on a first key operation on any key among the plurality of keys, a control information generator that generates control information for controlling, on the basis of a second key operation different from the first key operation, a mode of the musical sound produced on the basis of the first key operation, and a musical sound signal generator that generates a musical sound signal on the basis of the sound production information and the control information.

A new and improved Digital Musical Instrument includes a hardware segment that electronically detects the physical inputs of a musicians musical playing style or articulated intent; a Software segment that interprets and formulates the data output from the hardware segment, to be applied to any digitally modulated synthesizer or recording sampler; and an optional expanded method of sampling or digitally recording articulated sounds of acoustic instruments.

The present technology relates to a signal processing device, a signal processing method, and a program that enable intuitive operation of sound.

The signal processing device includes an acquisition unit that acquires a sensing value indicating a motion of a predetermined portion of a body of a user or motion of an instrument, and a control unit that performs non-linear acoustic processing on an acoustic signal according to the sensing value. The present technology can be applied to an acoustic reproduction system.

A virtual instrument for real-time musical generation includes a musical rule set unit for defining musical rules, a time constrained pitch generator for synchronizing generated music, an audio generator for generating audio signals, wherein the rule definitions describe real-time morphable music parameters, and said morphable music parameters are controllable directly by the real-time control signal. With this virtual instrument, the user can create new musical content in a simple and interactive way regardless of the level of musical training obtained before using the instrument.

A controller device for the production of electronic music includes multiple control surfaces, including a touch sensitive display and a matrix of actuator pads, each of which are capable of operating in different modes simultaneously.

An electronic cajon comprises a box-like base body with a bottom wall, side walls and a cover wall, wherein the playing surface is sub-divided into a plurality of beat effect zones, the beat effect zones each have a beat converting device arranged in a storage compartment formed in the front wall, the beat converting device has a rubber-like impact plate forming the operation surface of each beat effect zone, a mechanical-electrical signal converter mounted on the inner side of the impact plate and a shock absorption inlay arranged between the impact plate and a bottom of the storage compartment around the signal converter, and a sound module assigned to the signal converters is provided, which converts the electrical signals from the signal converters into electrical sound signals and outputs them at an output of the electronic cajon.

A sound source for an electronic percussion instrument and sound production control method thereof are provided. An electronic drum sound source device performs a weighting operation on four pieces of waveform information (pitch envelope, amplitude envelope, start phase) stored in a waveform table according to the beating conditions (hitting point position, velocity) based on the output from a struck sensor of an electronic drum pad. The electronic drum sound source device creates a sine wave on the basis of the waveform information whereon the weighting operation was performed, and generates musical sounds (sounds of percussion instrument) by synthesizing the sine wave with the waveforms of residual waveform data whereon the weighting operation was performed. The sine wave is not synthesized with waveform data other than the residual waveform data, and thus consistent musical sounds with no phase interference can be reproduced.
