G10H ELECTROPHONIC MUSICAL INSTRUMENTS; INSTRUMENTS IN WHICH THE TONES ARE GENERATED BY ELECTROMECHANICAL MEANS OR ELECTRONIC GENERATORS, OR IN WHICH THE TONES ARE SYNTHESISED FROM A DATA STORE
Introduced: September 1968
Description
G10H covers electrophonic musical instruments and devices that generate or synthesize musical tones through electromechanical or electronic means rather than purely acoustic mechanisms. This includes electronic keyboards, synthesizers, drum machines, digital audio generators, and hybrid instruments combining mechanical and electronic sound production. The classification encompasses both real-time tone generation via electronic circuits and algorithmic synthesis from stored data or algorithmic models. Related technologies such as MIDI control systems, audio effects processing integrated into instruments, and software-based sound synthesis engines fall within this scope, though purely acoustic instruments with electronic amplification only are typically excluded.
CPC subdivides this area 2x more granularly than IPC with 5 additional codes.
5 codes are CPC-only extensions.
Note: 5 CPC extensions are marked as secondary classification only.
1 shared codes have differing titles between IPC and CPC.
