Sound effects control system for musical instruments2010-03-10for
musical instruments comprises a tactile controller and a control box. The controller generates, by means of manual or other bodily manipulation, a control signal which is communicated to the control box. The control box receives an output signal from the
musical instrument and modifies it in accordance with the control signal received from the controller. The modified output signal is then communicated to a traditional amplifier which produces variations in the sound effects of the
musical instrument, such as volume, tremolo, reverberation, etc. The tactile controller comprises a fluid-filled lumen which, in combination with the compressible material of the controller, is collapsible in response to manual manipulation in order to generate a static pressure control signal for varying the sound effects of the
musical instrument. A wide variety of controller shapes, sizes, configurations, and locations on the
musical instrument are available.Claims

a control box in communication with said controller so as to receive said static pressure as a control signal, said control box receiving said output signal from said instrument and modifying it in accordance with said control signal to generate a modified output signal for varying the sound effects of said
musical instrument.
2. The system of claim 1, wherein said tactile controller comprises a tube that is positioned on a surface of said
musical instrument and wherein said musician depresses said tube towards said surface to induce said control box to generate a modified output signal.
3. The system of claim 2, wherein said lumen comprises a chamber having a first and a second end, wherein said first end of said chamber is closed and said second end of said chamber is in fluid communication with said control box.
4. The system of claim 3, wherein said tactile controller has a top and a bottom surface and wherein said bottom surface is adhered to said surface of said
musical instrument and wherein said upper surface of said tactile controller is rounded.
5. The system of claim 4, wherein said tactile controller has a cross-sectional width of approximately 0.25 inches, a height, from said bottom surface to an uppermost point on said upper surface, of approximately 0.25 inches and wherein said lumen is a concentric circular passageway having 0.125 inches diameter.
6. The system of claim 1, wherein said lumen of said tactile controller is air filled and said control box receives a pneumatic signal as said contro...

Electronic musical instrument2009-10-12An electronic
musical instrument comprising a host processor (10), process/engine interface (12) and sound engine (14) the latter utilizing partial control chip modules (32, 34) and a data path chip module (36) to effect multiple partial (Fourier) synthesis, in conjunction with a sound modelling technique, to generate up to 240 independent partials and impress time-varying amplitude envelopes on them and select and apply them to sound generation, each partial being controlled by selected parameters of frequency, amplitude, phase and attack/decay rate. A modulo-sumdither and oversampling approach to noise reduction is utilized in connection with the data path chip arrangement. Log sine addition is utilized to avoid multiplication apparatus ordinarily required to combine sine wave defining parameters.

What is claimed is:
1. Electronic
musical instrument comprising in combination:
means defining a digitized waveform for utilization with multiple input parameter selections,
means for making parameter selections via a user interface to generate digital inputs,
means for generating logarithms of multiple parameters, adding the same and converting the sum to antilog equivalent and feeding back on itself to produce a sample sum and,
means for applying the sample to output device and further comprising:
means for modulating the sample sum by clipping the bit length of each digital word thereof by clip rounding off the most significant bits, from an original n bit length, and further reducing into p bit length usable as a data unit bytruncate-elimination of the most significant p bits of n.
Description
BACKGROUND OF THE INVENTION
The present invention relates to electronic means for music generation and more particularly has as its object the provision of such instrument with a sound engine comprising an architecture enabling the application of thousands of stored unitsof music digital data to rapid production of analog speaker-driving forms, utilizing practical solid state circuit means.
The invention is described below with reference to electronic piano usage, but is also usable in a number of other electronic
musical instrument roles to provide, singly or combined, the sounds of a variety of instrument, elements of human voiceand other sound sources and in analogous instrument contexts not involving music or voice, but involving comparably varying waveform data.
Multiple Partial (Fourier) Synthesis is a technique well known in engineering practice. Any arbitrary periodic waveform (e.g.,
musical instruments' sound) may be reproduced by summing up a series of sine waves of appropriately determinedfrequencies, amplitudes, and relative phases. This technique allows great flexibility, much more so than subtractive synthesis (which starts out with a complex waveform and filters out unwanted spectral content) or wave-table synthesis (which can onlyreproduce whatever is in the table).
It is the object of the present invention to establish effective instrumentation using Fourier synthesis.
SUMMARY OF THE INVENTION
The
musical apparatus of the invention inputs a stream of digital signals which represent a sequence of audio notes to be ultimately produced. The apparatus creates a sequential list of partials and impresses time-varying amplitude envelopes onthem, such that the sequential list completely characterizes the desired audio signal. A multiple partial synthesis, sometimes referred to a...
Electronic musical instrument with semi-automatic playing function2009-09-22h4>AbstractIn an electronic
musical instrument, playing data are produced by depressing a key in a keyboard, and divided into plural groups. At least one of the semi-automatic playing channels processes sound data of a
musical piece read out of a memory to generate
musical tones in synchronism with the playing data of at least one group. The sound data may be corrected according to sound correcting data before being used to generate
musical tones.Claims
