The user interface module further includes at least one input blend controller and a voice controller configured to allow a user to select a patch from a plurality of available patches, with each patch of the plurality of available patches comprising a configuration of one or more audio effects set at various levels to arrive at a desired effect template.

A preamplifier for musical instruments includes: an operational amplifier 40 to amplify an inputted analog audio signal; a dual-unit variable resistor 30 to change an amplification factor of the operational amplifier 40 by manually operating an operation unit; an A/D converter 51 to convert the amplified analog audio signal to a digital audio signal; and a digital signal processor 60 to digital-signal process the digital audio signal, wherein the dual-unit variable resistor 30 includes a second variable resistor 32 to output a detection signal in accordance with an amount of operation of the operation unit, and the digital signal processor 60 is capable of implementing, based on a value of the detection signal, a first digital gain process to amplify the digital audio signal and/or a second digital gain process to attenuate the digital audio signal.

A device is provided as part of a system, the device being for capturing vibrations produced by an object such as a musical instrument. Via a fixation element, the device is fixed to a drum. The device has a sensor spaced apart from a surface of the drum, located relative to the drum, and a magnet adjacent the sensor. The fixation element transmits vibrations from its fixation point on the drum to the magnet. Vibrations from the surface of the drum and from the magnet are transmitted to the sensor. A method may further be provided for interpreting an audio input, such as the output of the sensors within the system, the method comprising identifying an audio event or grouping of audio events within audio data, generating a model of the audio event that includes a representation of a timbre characteristic, and comparing that representation to expected representations.

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.

A singing voice edit assistance method, performed by to computer, includes: judging whether phoneme data based on which waveform data for listening contained in a data set for singing synthesis is synthesized, is available or not for a user to edit a singing voice, the data set for singing synthesis containing score data representing a time series of notes, a lyrics data representing words corresponding to the respective notes; and synthesizing the waveform data for listening while shifting pitches of phoneme data, representing waveforms of phonemes, indicated by the lyrics data to pitches indicated by the score data and connecting the pitch-shifted phoneme data and, if the indicated phoneme data is not available, the synthesizing synthesizes waveform data for listening based on the score data, the lyrics data, and substitute phoneme data available for the user instead of the indicated phoneme data.
