Abstract

1,216,080. Electrons musical instruments. CHICAGO MUSICAL INSTRUMENT CO. 4 Dec., 1967, No. 55126/67. Heading G5J. [Also in Division H3] In an electronic music generation system, Fig. 1, signals from single note generators 22, 22a &c., are modified, by sawtooth waves derived from wave shapers 25, driven by a multiphase oscillator 21, to produce percussion and reiteration effects. The modified signals drive tone colour filters 24, are combined on an output line 12 with other signals from conventional sources 11, are amplified at 13 and drive loud-speaker 14. In one embodiment (Fig. 2, not shown), the oscillator (21) is a multivibrator producing a rectangular output in each of two tone generator channels (# 1 , # 2 ), each channel including a wave shaper (25a, 25b) producing sawtooth waves of opposite phase at its terminals, each sawtooth, via an amplitude control circuit 23, determining the amplitude envelope of a signal from a source in the generator channel. These signals are combined in desired phase relationships to give percussion, reiteration, tone colour vibrato and speaking effects. The multivibrator may be free running, keyed by an audio signal at an input (38) or by grounding an alternative input (44), or one shot, keyed at input (38), and the multivibrator frequency may be varied by resistors (45, 46, Fig. 2, not shown). In another embodiment (Fig. 4, not shown) outputs (# 1 , # 2 ) of multivibrator (21) couple, via switches (73, 71) the outputs of tone sources (64, 66) to an amplitude control (23) and at the same time the (# 1 and # 2 ) outputs are coupled by selector switches (68, 70) to a wave shaper (25c). The opposite phase sawtooth outputs at the wave shaper terminals are selectively coupled by a switch (75) to the amplitude control circuit to produce the desired amplitude envelope for the tone signals passed by switches (73, 71) and the amplitude control circuit output drives a single tone colour circuit 24. In a third embodiment (Fig. 5, not shown) an amplitude controlled signal from a single source (83) is selectively applied to tone colour filters (24a, 24b) by switches (81, 82) controlled by the multivibrator (21).
