When a processor accepts an input of plural notes to be assigned for tone generation, according to a predetermined note determining rule called assignment type, the processor selects one or more notes to be sounded in each of plural parts from the accepted notes. The processor controls a display unit to display, for each of the plural parts, the accepted plural notes to be assigned for tone generation. At this time, non-selected one or more notes in respective parts are displayed in one style, and the selected one or more notes in the respective parts are displayed in another style different from the one style. Alternatively, the plural notes to be assigned for tone generation are displayed in one style, and, for each of the plural parts, the selected one or more notes are displayed in another style different from the one style.

An electronic device is provided. The electronic device includes a touch screen display, at least one of a speaker and a sound interface, a processor configured to electrically connect to the touch screen display, the speaker, and the sound interface, and a memory configured to electrically connect to the processor. The memory stores instructions for, when executed, causing the processor to display at least one item comprising a musical instrument shape on the touch screen display, receive a touch input through the touch screen display, load sound data corresponding to the at least one item based on the touch input, process the sound data based at least in part on information associated with the touch input, and output the processed sound data through the speaker or the sound interface.

Systems and methods for multi-pressure interaction on touch-sensitive surfaces are disclosed. One disclosed embodiment of a method comprises receiving a first sensor signal from a touch-sensitive input device in response to a first contact of a first object on the touch-sensitive input device, the first sensor signal comprising a first location and a first pressure of the first contact, receiving a second sensor signal from the touch-sensitive input device in response to a second contact of a second object on the touch-sensitive input device substantially simultaneously with the first contact, the second sensor signal comprising a second location of the second contact and a second pressure of the second contact, generating a signal based at least in part on the first sensor signal and the second sensor signal, the signal configured to cause a haptic effect, and outputting the signal.

Improvisation or playing along with a musical group or with a song is enjoyable to people and musicians of all ability levels. However, it is easy to play notes which do not harmonize with other notes and pitches which are being played. Provided herein is a method, computer program product and electronic device for assigning a set of pitches to a plurality of cells of an electronic device having a touch screen input device. The method may include the steps of obtaining an input chord, disassembling the chord into at least one base note and a plurality of individual voices, arranging a predetermined number of voices of the chord according to at least one predefined rule, and assigning at least one set of pitches to a plurality of cells of an electronic device, said set of pitches corresponding to the base note and arranged predetermined number of voices of the chord. The present method allows a musician to freely play along without the possibility of playing an errant note as the user does not control the actual pitch associated with the cells being indicated by a user on the touch screen.

An apparatus is provided for simulating a musical instrument, comprising: a display configured to present a musical interface associated with an external image; a musical instrument setter configured to associate the musical interface with the musical instrument; and a sound area controller configured to arrange a portion of the musical interface as a sound area.

Disclosed are an apparatus and a method of generating a sound by using a touch screen. A sound modulation apparatus according to the present invention includes: a sensor information input unit configured to receive sensing information on a position, at which a touch input of a user is applied to the screen, and pressure according to the touch input applied to the screen; and a sound modulation unit configured to set a tone frequency and volume of a sound to be output, and set the tone frequency according to the position, to which the touch input of the user is applied, and set the volume according to a size of the pressure according to the touch input.

A stringless electric bowed musical instrument is disclosed in which sensors are provided to detect finger positions and bowing motions of the player. A touch-sensitive fingerboard surface is equipped with pitch sensors that detect finger positions. Use of a fingerboard surface that includes an interactive flexible touch screen display provides a plurality of illumination patterns to be displayed on the fingerboard and permits various operational modes that are useful for both students and artists. A bowing platform in contact with either the fingerboard or the body of the instrument provides an adjustable bowing surface for including bow sensors configured to detect vibrations in response to bow motion. The bow sensors may include piezo-ceramic elements. Optical pitch sensors may sense interruption of one or more laser beams that propagate above a top surface of the fingerboard.

The present invention relates to a polypeptide having protease activity comprising a zinc finger protease domain, a helix-turn-helix domain and a GAF domain. The core protein sequence of the protease is shown as SEQ ID NO: 1. The invention also relates to optimized reaction conditions for the protease and methods of increasing the protease activity.

Systems and methods for multi-pressure interaction on touch-sensitive surfaces are disclosed. One disclosed embodiment of a method comprises receiving a first sensor signal from a touch-sensitive input device in response to a first contact of a first object on the touch-sensitive input device, the first sensor signal comprising a first location and a first pressure of the first contact, receiving a second sensor signal from the touch-sensitive input device in response to a second contact of a second object on the touch-sensitive input device substantially simultaneously with the first contact, the second sensor signal comprising a second location of the second contact and a second pressure of the second contact, generating a signal based at least in part on the first sensor signal and the second sensor signal, the signal configured to cause a haptic effect, and outputting the signal.

Various embodiments are provided generally relating to providing a strum pad on a user device. In some embodiments, a musical arrangement may be provided on a user device. A score of the musical arrangement may be tracked as it plays. In some embodiments, gestures may be detected on the user device while the user device plays the musical arrangement. In response to detecting the gesture, a component piece for the musical arrangement may be outputted. In some embodiments, the outputted component piece may correspond to the tracked score of the musical arrangement.
