Abstract: Processor-implemented methods and systems for polyphonic note detection are disclosed. The method includes converting a portion of a polyphonic audio signal from a time domain to a frequency domain. The method includes detecting a fundamental frequency peak in the frequency domain. The method then detects a defined number of integer-interval harmonic partials.

For example, this method allows detection of each note in a strummed guitar chord to provide feedback on the tuning of each string in a strummed chord or allows detection and feedback of the timing and pitch errors for guitar chords played along with a reference track.

The both-communication states provide said in and out-communication states simultaneously. In the out-communication states, tone data are sent to the external apparatus connected to the musical tone (internal) apparatus. In the in-communication states musical tone data are sent only within the musical tone (internal) apparatus.

Each of specified samples among the samples in the first to fourth groups is corrected in response to the slope decision result and the selected coefficient.

Abstract: An electronic high-hat circuitry system allows the drummer to manually choose the sounds that an electronic high-hat makes when the drummer's foot is off of the pedal and the high-hat instrument is struck. When the pedal is at or near the top of its travel, a primary circuitry switch disables normal foot-controlled positioning circuitry and enables a secondary circuit that sends a selected positioning signal to a drum module. When the pedal is again pressed down, the primary circuitry switch returns control to the primary, pedal controlled circuit. An optional tertiary circuit allows for the choosing of a different sound when the secondary circuit is activated and the high-hat cymbal is tilted. A control panel is used by the drummer to select the desired high-hat sounds of the secondary and tertiary circuits. Also, high-hat instruments are introduced that have removable foot pedals, or no foot pedal.

Abstract: This application describes a method and an apparatus which enable one to compose music using hierarchical musical scales and harmonic sequences, where each harmonic sequence of a higher level is derived from the one on the lower level.

When composing for an orchestra of multiple instruments, harmonic sequences and scales can be assigned independently to each musical instrument.

Abstract: When a signal representing a first set value or more is received from a detecting section, a determination is made whether a boost value is a predetermined value or more. When the boost value is the predetermined value or more, a currently set boost value is reduced by a predetermined step, so that a new boost value is set. Further, when the boost value is less than the predetermined value, a currently set volume level is reduced by a predetermined step, and a new volume level is set. Therefore, in a case when the set boost value is gradually reduced and the boost value is finally less than the predetermined value, the audio signal is still the first set value or more, the volume level is further reduced by each predetermined step. Therefore, an audio signal can be securely prevented from being clipped.

On the other hand, if an automatic reading file has been already read, the automatic reading file stored in the storage section may be edited on the basis of it.
