US Patent:

54252970, Jun 20, 1995

Filed:

Feb 19, 1993

Appl. No.:

8/021524

Inventors:

Leroy D. Young - Davie FL

Assignee:

Conchord Expert Technologies, Inc. - Miami FL

International Classification:

G10H 700
G10H 138

US Classification:

844832

Abstract:

A new electronic musical instrument and an associated notational method are disclosed. The new musical instrument is played using the right hand for depression of keys, as in conventional instruments, and also by applying finger pressure onto special sensing areas using the left hand. The left hand sensing areas or keys are located so as to be accessed without any significant lateral movement of the left hand. "Instructions" for playing the new instrument are conveyed to the user via directly translatable notational symbols printed on an associated surface. This cooperating system removes the mental translational and physical movement problems of conventional notation and conventional instruments by having the notational method directly convey the physical actions that are required and by simplifying the physical actions themselves. Such a cooperative system allows users to quickly play this instrument at advanced levels.

US Patent:

Filed:

Dec 19, 1979

Appl. No.:

6/105160

Inventors:

Leroy D. Young - Miami FL

International Classification:

G10H 300

US Classification:

84 116

Abstract:

A musical instrument for cooperation with an electronic synthesizer having a parallel-control fretboard on a mountable neck member. Electronics associated with the neck member provide accurate volume, gate and frequency control signals for a synthesizer while still permitting normal guitar playing nuances such as hammer-offs, hammer-ons, slides, muting, and bends. A preferred embodiment employs a micro-processor and a multiple string fretboard.

International Classification:

H04J 324

US Classification:

370 851

Abstract:

An apparatus for controlling access to a time division multiplexed (TDM) bus includes a frame address register having a plurality of storage registers for storing a plurality of frame addresses designated for use in communicating over said TDM bus. A frame address latch stores a current frame address. A frame comparator, coupled to the frame address register and the frame address latch, compares the designated frame addresses with the current frame address and produces a first signal indicative of the storage register containing a frame address matching the current frame address. A time slot register has a plurality of storage registers for storing a time slot number designated for use in communicating over said TDM bus. A time slot generator generates a current time slot number. A time slot comparator, coupled to the time slot register and the time slot generator compares the designated time slot number with the current time slot number and produces a second signal indicative of the storage register containing a slot number matching the current time slot number.

Appl. No.:

6/464386

Inventors:

Leroy D. Young - Miami FL

Assignee:

John Ellis Enterprises - Nashville TN

International Classification:

G10H 100

US Classification:

84 101

Abstract:

Apparatus for detecting note selection on a guitar fretboard including a differential amplifier for detecting voltage drops across successive fret pairs, a multiplexer for connecting successive fret pairs to the differential amplifier, counters for maintaining an indication of the string and fret position under examination, and a shorting string placed across the frets for insuring reliable circuit operation.
