Abstract

1418737 Electrophonic musical instruments WURLITZER CO 22 Feb 1973 [29 Feb 1972] 8651/73 Heading G5J An electrophonic musical instrument comprises means for generating a plurality of tone signals, a keyboard having at least two discrete parts to control the signals, means for applying the tone signals to two parallel channels and means rendering one or other channel operative according to which part of the keyboard is played on. The output of a master oscillator, described in detail with reference to Fig. 11 (not shown) and shown as 78 in Fig. 2, at about 1À5 MHz is applied to an LSI divider chain which provides 12 outputs at semitone intervals to a network 84 and 13 outputs to network 92. Networks 84, 92 select the highest note played in their parts of the keyboard 100, 104; 102, 106, and directs the tone signal to the two channels AA<SP>1</SP> and BB<SP>1</SP>. A steering circuit 112 described in detail with reference to Fig. 12 (not shown) detects which part of the keyboard is played on and applies a signal on either lead 190 or 192 to enable either channel AA<SP>1</SP> or BB<SP>1</SP>. Channels A<SP>1</SP> and B<SP>1</SP> produce thirds of chords while channels A and B produce fifths and with further division at 144 and 162, roots. The outputs of channels AA<SP>1</SP>, BB<SP>1</SP> are applied through tone filters 136 to an output system 138, 140. The above described keyboard is provided as an additional keyboard on a conventional electrophonic organ to give the facilities of a synthesizer. Vibes, xylophone, glock and chimes are simulated by giving the high frequency components a shorter envelope than the lower frequencies. Wah-wah may be similarly provided by detuning an active filter, Fig. 9 (not shown) which includes two light dependent resistors (512, 516) lit by a tungsten lamp or light emitting diode (538) fed by an attack pulse. Delta pitch, vibrato and possibly wah-wah are provided by detuning the master oscillator either during attack or cyclicly and the synthesizer keyboard may have a "second touch" facility for bringing in the effects, i.e. there is a second switch operable by any of the keys on depression past their normal actuated position.
