300 | DD | ELECTRONIC MUSICAL INSTRUMENTS {structural combinations of microphones, pick-ups, or amplifiers with musical instruments subclasses 1+, 50+, and 100+; Instruments in which each note is generated by a different individually-actuated mechanical resonating structure and is amplified electrically subclasses 50+; Instruments in which each note is produced by a different electrically-vibrated sounding element subclasses 100+; Electronic circuits in general H03. {G10H} {4} |
388 | DD | .~ Instruments in which the tones are synthesized from a data store, e.g., computer organs,etc. {synthesis of acoustic waves not specific to musical instruments G10K 15/02, G10L} {G10H 7/00} {4} |
391 | DD | .~.~ In which amplitudes at sucessive sample points of a tone waveform are stored in one or more memories {G10H 7/02} {2} |
