Keyboard device of electronic musical instrument2010-03-20 00:00:00of said radius of curvature.DescriptionVarious types of keyboard devices have been developed to allow a smooth and proper manner of striking or touching the keys of a keyboard instrument and to improve durability thereof. However, these conventional keyboard devices have respective advantages and disadvantages. Only a few keyboard devices are proposed in consideration of operability at the time of assembly or disassembly for a repair.
A typical keyboard device aimed at the smooth touch has a common shaft on which back end portions of the keys are mounted. These keys are aligned to be parallel to each other along a direction perpendicular to the common shaft and can be selectively pivoted about the common shaft. According to this keyboard device, the common shaft must be inserted after all keys are completely aligned. Further, when any one of the keys is to be replaced, the common shaft must be removed from all the keys located outside the key to be replaced, resulting in inconvenience. Such a conventional keyboard device is described in U.S. Pat. No. 3,740,448.
Another conventional keyboard device is proposed wherein support shafts are respectively provided for all keys, and each key has a U-shaped back end portion whose side walls must be expanded outward and mounted on two ends of the corresponding shaft the center of which is fixed. According to this keyboard device, the side walls of the back end portion of each key must be expanded outward, and assembly and disassembly operations are time-consuming and cumbersome. A typical example of the keyboard device of this type is described in Japanese Utility Model Application Disclosure No. 57-60191.

According to an aspect of the present invention, there is provided a keyboard device of an electronic musical instrument, comprising:
a keyboard frame;
a plurality of keys which are aligned on the keyboard frame and which are vertically pivotable;
a plurality of return springs each of which corresponds to one of the keys and has one end stopped by the key and the other end stopped by the keyboard frame so as to bias the key toward a nonstruck position; and
a plurality of pivot members each of which is disposed on the keyboard frame in a direction perpendicular to a longitudinal axis of the key to correspond to one of the keys, and has an arcuated surface to be brought into slidable contact with a back end portion of the key so as to allow the key to perform pivotal movement,
the back end portion of the key being spring-biased against the arcuated surface of the pivot member by means of the return spring.

Electronic musical instrument2009-10-12 00:00:00of 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 Fourier Synthesis, is formed.
Each partial from the sequential list is digitally generated by stepping through a ROM containing a single cycle forming the frequency of that partial and combining it with the amplitude envelope for that partial resulting in a signal with thedesired frequency, amplitude, duration and attack and decay rates. All the partials are summed into a digital data stream which is converted to an analog form, filtered and made available for use, for example by an audio amplifier and speakers producingsound.
With reference to the preferred embodiment a sine wave is digitally stored and sensed at an appropriate rate of change of phase angle per sample frequency of a given partial. The phase angle determines the next value selected from the storedsine wave so that changing the rate of change of the phase angle changes the resulting frequency. The stored amplitude is scanned synchronously with the sine wave scanning in a pipe line design ensuring the proper time relationship between the two. Since a partial is a waveform multiplied by an amplitude, both are stored in log form, then added and the anti-log generated forming the resultant partial as a digital stream of signals.
The technique has many useful properties. One is that the quality of a given sound increases as more partials are used to represent it. Another is that partials are controlled independently of one another. This feature allows less importantpartials to be "stolen" from notes already sounding, and used to form new notes. Taken together, these two properties allow both the ability to play many complex timbres simultaneously, as well as allowing enhanced quality for notes played singly or insome instances against a demanding background of silence. This is in contrast to many commercially available synthesizers, which allow only a limited number of voices. The latter force entire previously played notes to be silenced as more notes areplayed (e.g., a 10-note chord played on an 8-voice synthesizer).
Additionally, multiple partial synthesis can be used with sound modelling data stored in one or more read only memories to lower the cost of extra installed voices, because of the greatly reduced storage requirements that go withpartials-synthesis. One second of waveform table as in conventional wave table storage may be tens of Kilobytes, whereas the information that describes a sound and the 10 to 50 partials needed to synthesize the same sound with the present inventionwould be smaller by a factor of up to 20. Similarly, having several voices available at once for a keyboard split or orchestral effect is much less expensive.
The sound model data comprises, in accordance with the inve...

20: The Younger Generation Enjoys The Rich Sound Of Vinyl On The New Audio Turntables
2009-08-29 00:00:00The CDs out there have a pristine sound, but records provide a better sound. Younger kids like the cover art on the records as well, according to James Patterson, age 17, who doesn't even remember when they LPs were popular in the past. He found some old LPs up in the attic at his grandparents home by the Beatles and the Rolling Stones, then his uncle grabbed him a player on eBay and he know displays it in his room.<br /><br />Replica turntable systems are available from various manufacturers. They look like the past machines but have today's technology used in them. A few top manufacturers include Memorex, jWin, Teac, and Crosley. Various functions are included, which includes USB connections, stacking up multiple LPs, and even recording from the LPs to CD as well.<br /><br />Raman of Classic Buys says that Nostalgia turntables are among the best seller audio electronics during gift giving Christmas season. Nostalgia turntables from popular brands like Crosley, Teac, Memorex and Thomas Pacconi are the top picks.<br /><br />Shoppers are looking for the best brands and great features when they purchase audio turntables today according to The Magma Group president. They prefer to go with systems that are four in one, playing the radio, ...
