A musical instrument digital interface (MIDI) controller is provided. It has a housing having a hollow interior portion, a first audio jack and a second audio jack positioned on the housing, wherein the first audio jack is configured to accept a first audio signal from an electronic music instrument, and wherein the second audio jack is configured to accept a second audio signal from a microphone, a conversion module configured to receive the first signal from the first audio jack and the second signal from the second audio jack, wherein the conversion module is configured to transform the first signal into an outgoing digital signal and retain the second signal in a database and an output module configured to utilize the outgoing digital signal and the retained second signal from the database, and output both signals as a dual signal of audio and digital outputs during a user performance.

The teachings described herein are generally directed to a system, method, and apparatus for separating and mixing tracks within music. The system can have a video that is synchronized with the variations in the musical tempo through a variable timing reference track designed and provided for a user of the preselected performance that was prerecorded, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected performance.

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.

A computer implemented method for analysing sounds, such as audio tracks, and automatically classifying the sounds in a space in which arousal is one axis and valence is another axis. The location of a sound or track in that arousal-valence space is automatically determined using a computer implemented system that analyses, measures or infers values for each of the following base feature parameters: harmonicity, turbulence, rhythmicity, sharpness, volume and linear harmonic cost, or any combination of two or more of those parameters.

A musical sound playback method that is performed by a processor using data in a memory, including generating a plurality of interpolated data where input data for a segment corresponding to musical sounds has been interpolated, based on values in the input data which are related to both the segment corresponding to the musical sounds and a change amount of the musical sounds, generating a plurality of instruction data for providing instructions regarding musical sound states to be achieved at a plurality of timings in the segment, based on the plurality of interpolated data, and sequentially transmitting the plurality of instruction data to a sound source circuit so as to cause the sound source circuit to generate the musical sounds while sequentially changing the musical sounds to be in the musical sound states instructed by the instruction data, when a musical sound playback for the segment is performed.

When transferring waveform data from a waveform region in a high-capacity flash memory to a waveform buffer in a RAM, first, whether a non-ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the allocated non-ring buffer region. If such a non-ring buffer region cannot be allocated, then whether a ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the ring-buffer region in a ring buffer operational manner.
