DIFF Subgroup
G10H 7/02 in which amplitudes at successive sample points of a tone waveform are stored in one or more memories
Introduced: January 1990
Full Title
Instruments in which the tones are synthesised from a data store, e.g. computer organs > in which amplitudes at successive sample points of a tone waveform are stored in one or more memories
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1990.
