US Patent:

43388434, Jul 13, 1982

Filed:

Jan 11, 1980

Appl. No.:

6/111458

Inventors:

Stephen A. Wise - Macungie PA

Assignee:

Allen Organ Co. - Macungie PA

International Classification:

G10H 100

US Classification:

84 101

Abstract:

An asynchronous interface between a data input system (computer) and the keyboard multiplexer of an electronic musical instrument (digital organ) includes a pair of RAMs. The interface synthesizes the multiplexed keyboard data stream of the digital organ by swapping read and write operations between the two RAMs. Predetermined key data (WRITE DATA) provided by the computer is written into one RAM during a WRITE interval while key data (READ DATA) previously written into the other RAM is sequentially read out of the latter RAM. The WRITE DATA designates those keys on the organ keyboard which are to be simulated as being active. The read and write operations are alternately applied to each RAM. If the READ DATA matches the key code assigned to a key on the keyboard, the appropriate note is sounded by the organ. The two RAMs can actually be two segregated portions of a single memory.

Abstract:

A keyboard teaching device for the self-instruction of a student of keyboard musical instruments is provided which enables the student to correlate the positions of the keys on a musical instrument keyboard with the positions of the notes on a musical scale. A keyboard having a plurality of keys corresponding to the notes of a musical scale for generating a first set of control signals in an initialization or set-up mode and key-note correlation signals in an instruction or game mode, at least one storage means having a predetermined combination of logical signals providing a source for a random sequence of one or more notes over a predetermined range in the game mode for generating a second set of control signals in response to the actuation of one or more keys in either mode and a means for generating audio tones and displaying video images in accordance with the first and second sets of control signals enables the student to visually and audibly check his or her selection of one or more of the keys.
