Large scale integrated circuit generator chip for electronic organ.

摘要

An electronic organ or the like is provided with a plurality of large scale integrated circuit (LSI) chips (10-30), each of which has six tone generators (50) capable of generating a frequency corresponding to any not on the organ. In accordance with a preferred embodiment of the invention a sufficient number of these chips (10-30) is provided so that there is one note generator for each key of the organ. Each chip (10-30) is assigned to one half octave of the keyboard, whereby outputs are in one half octave note groupings. This allows for filtering of the square waves generated to provide a very high quality flute tone.
