A user-customizable modular music effects pedal is described. The music effects pedal includes a base having an input, an output and a connector. The input receives a music signal. The connector is coupled with the input and has an electrical form factor and a physical form factor. The electrical form factor is configured to fit a corresponding electrical form factor of an effects cartridge. The physical form factor is configured to fit a corresponding physical form factor of the effects cartridge. The connector provides the music signal to the effects cartridge and receiving a processed signal from the effects cartridge. The effects cartridge includes effects electronics to provide the processed signal. The output is coupled with the connector and provides an output signal based on the processed signal from the effects cartridge.

Embodiments are provided for a tone effects base unit, system, and method of using the tone effects base unit. A tone effects base unit includes an integrated housing and one or more slots integrated into the housing. The one or more slots are configured to receive reversible sound effects cartridges, whereby the reversible sound effects cartridge include one or more sound effects that are applicable to sound produced from an electric instrument and emitted from an amplifier. A tone effects base unit is configured to include one or more effects mode lights associated with each slot so that the one or more effects mode lights is illuminated a predetermined color depending on whether a reversible sound effects cartridge is inserted into the slot or not and depending on whether the reversible sound effect cartridge is inserted in a normal mode or in an FX loop mode orientation.

Disclosed is a piano learning guidance system, comprising a piano and two hand drums, wherein the piano comprises a control module, a storage module, a first LCD display screen, a second LCD display screen, a third LCD display screen, a key recording microphone and a plurality of first LED light bars in one-to-one correspondence to keys of the piano, and each first LED light bar is formed by a plurality of first LEDs; the storage module, the first LCD display screen, the second LCD display screen, the third LCD display screen and the key recording microphone are all electrically connected to the control module; the hand drum comprises a second LED light bar and a pressure sensor, and the second LED light bar is formed by a plurality of second LEDs; and the second LED light bar and the pressure sensor are electrically connected to the control module.

A portable amplification unit that is integrated directly into the body of an electric instrument, thus eliminating external cables and devices. The portable amplification unit includes an amplifier cartridge that houses an amplification assembly. The amplification cartridge is attached to, and electrically connected to, an instrument through a cartridge receiver. A pre-amplifier assembly of the amplification assembly provides a first stage of amplification, while a power amplifier circuit provides a second stage of amplification. A power supply provides current to amplify the electrical signal of the instrument. A pre-amp control and a master volume control allow for adjusting the magnitude of amplification. A speaker is also integrated into the amplifier cartridge; the speaker being electrically connected to the power amplifier circuit.

The invention relates to an electronic musical instrument system (1) for influencing the sound of an electric musical instrument having a housing (2) that has signal ports (14, 18) and a power supply port (15). In order to simplify the individual combination of different audio effects, the housing (2) contains control electronics (6) that have associated slots (4a-4f) for effects modules (19), wherein the slots (4a-4f) are arranged in the housing (2) and each slot (4a-4f) has a multipin connection (5a-5f) for connection to a plug-in effects module (19). The invention additionally relates to a corresponding effects module (19).

A method for the communal construction of an audio harmonized electronic card includes loading a greeting card template in response to a request by an initial author. The method also includes receiving a voice track of the initial user along with a textual message and a designated recipient of an electronic card. The method yet further includes transmitting an invitation to a subsequent user with an embedded reference to the loaded card template. Thereafter, a voice track of the subsequent user is received from the subsequent user. Consequently, the voice tracks are composited into a single harmonized audio track with each of the voice tracks providing harmony to the other. An electronic card is then generated by embedding the textual message and the harmonized audio track into the loaded card template. Finally, the electronic card is transmitted to the designated recipient.

A movement actuated tone effects system is provided for manipulating the electrical signal of an electric instrument by moving the electrical instrument in relation to a set of reference axes. A movement actuated tone effects unit is positioned within the electric instrument or within an effects cartridge attached to the electric instrument via a cartridge receiver. The movement actuated tone effects unit includes a motion sensor unit, a processor, a tone effects circuit, and a power source, wherein the motion sensor unit measures the motion of the electric instrument and generates electrical signals directed to the processor. The processor analyzes the electrical signals, determines the appropriate tone effect to apply, and then directs the tone effects circuit to produce the desired tone effect. The movement actuated tone effects unit may further include an integrated speaker, a signal converter, a transmitter, and a device terminal.

An electronic device and a data usage method are provided. An electronic musical instrument confirms whether respective sound data stored in a timbre memory or a wave memory can be used or cannot be used based on management information acquired from a server. A sound data determined to be usable in the management information is validated so that it can be used for loading or writing. On the other hand, a sound data determined to be unusable in the management information is invalidated so that it cannot be used.
