Title: Electronic organ control for multiple production - requires as many oscillators as voices and changeover switches
Inventor: SCHOENE PETER
IPC: G10H1/18
Filed: 1973-06-16
Abstract: An electronic organ which can play chords produces two or more notes for different voices simultaneously and has a many oscillators as the max. number of notes in any chord or combination of voices. The keys for each note actuate the corresponding number of change over switches; there may be two for each key so that one of them connects one oscillator to the tuning resistor belonging to the key concerned, whilst the other connects the second oscillator to the bank or other keys, ready to co-operate with one of them. This saves the costs for additional oscillators, yet imposes no limitation on the relative distance of the notes to be sounded.
