Sound effects control system for musical instruments2010-03-10 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

Assessment Tool For Storing and Sharing Music Therapy Patient Records2010-03-04analysis may be guided by a scale or kit such as is possible with the Test of Adolescent/Adult Word Finding. However, informal analysis can also be performed and recorded based on a therapist's own expert skills and knowledge. Such informal analysis can be recorded in written, audio or video formats or combinations thereof.
[0018]The assessment tool can store case studies conducted by therapists. A case study is generally an in-depth, longitudinal examination of a single patient. Such a case study provides a systematic way of observing a patient, collecting data and analyzing the information. A case study may optionally present, as well as test, a hypothesis. Such case studies can be recorded in written, audio or video formats, or combinations thereof.
[0019]Audio recordings can be stored by the assessment tool. Such audio recordings can be of but are not limited to music, singing, speech, sounds or combinations thereof. Non-limiting subjects of audio recordings include patients, therapists, assistants to the therapist, musicians,
instruments, animals, nature, machines, phenomena or any combination thereof. The subject can be a single person or thing or a group of persons or things.
[0020]Video recordings can be stored by the assessment tool. Such video recordings can be of, but are not limited to therapy sessions, performances, practice sessions, common situations, experiments, and concerts. The video recordings can be real-time motion, slow motion, time-lapse, still images or combinations thereof. Video recordings can be photographs. The video recordings can be of any part or the entire electromagnetic spectrum, including but not limited to the full visual spectrum of light, black and white only, grayscale, infrared, ultraviolet, single hues or combinations thereof.

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 as a Fourie...
