Abstract
1506271 Electronic musical instruments HAMMOND CORP 4 March 1975 [4 March 1974] 8919/75 Heading G5J In a monophonic instrument such as a synthesizer, keys 10 produce control signals on individual leads 40 for each note, control signals corresponding to notes of the same name are collected at 60 and employed to gate out the appropriate tone from a top octave generator 100 to a set of dividers 170 and control signals corresponding to individual octaves are colected at 70 and employed to gate out the tone in the correct octave from the respective frequency divider 170. In the simple form of Fig. 2 only one key may be operated at a time. In an alternative (Fig. 1, not shown) which allows the instrument to share one keyboard of a fully polyphonic organ (not shown) a low octave lock out circuit and note and octave preference circuits (Figs. 3, 4, not shown) of the kind described in U.S.A. Specification 3,766,305 are incorporated so only the tone corresponding to the highest key pressed is sounded. Further circuits of the monophonic instrument are described in Specifications 1,506,272 and 1,506,273.
