Abstract
Abstract In an electronic organ, a first means for producing musical tone signals is connected via a first field effect transistor (FET) gate to a first loudspeaker; a second means for producing musical tone signals different in characteristics with respect to pitch and/or tone color is connected via a second FET gate to a second loudspeaker; the first means is also connected to the second loudspeaker via a third FET gate; and the second means is connected via a fourth FET gate to the first loudspeaker. Three pairs of means are disclosed: 1. The first means comprises a tone signal source in series with a key switch and a first tone color filter, while the second means comprises the same signal source in series with the same key switch and a second tone color filter different from the first filter. 2. The first means comprises a first tone signal source in series with a first key switch and a first tone color filter, while the second means comprises a second, octavely related tone signal source in series with a second key switch and a second tone color filter which is different in characteristics from the first tone color filter. 3. Same as 2, except that the first and second filters are similar.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
In an electronic organ system having a first and a second loudspeaker, the combination comprising: first means supplying a first tone signal; second means supplying a second tone signal having characteristics different from said first tone signal; a first gate coupled between said first means and said first loudspeaker; a second gate coupled between said second means and said Second loudspeaker; a third gate coupled between said first means and said second loudspeaker; a fourth gate coupled between said second means and said first loudspeaker; and additional means for rendering said first gate and said third gate conductively concurrently and reiteratively and for rendering said second gate and said fourth gate conductive concurrently and reiteratively but 180* out of reiteration phase with respect to first and third gates.
Claim 2
Dependent Claim
128 words
In an electronic organ system having a first and a second loudspeaker, the combination comprising: first means supplying a first tone signal; second means supplying a second tone signal having characteristics different from said first tone signal; a first gate coupled between said first means and said first loudspeaker; a second gate coupled between said second means and said Second loudspeaker; a third gate coupled between said first means and said second loudspeaker; a fourth gate coupled between said second means and said first loudspeaker; and additional means for rendering said first gate and said third gate conductively concurrently and reiteratively and for rendering said second gate and said fourth gate conductive concurrently and reiteratively but 180* out of reiteration phase with respect to first and third gates.
Claim 3
Dependent Claim
42 words
The combination according to claim 1, wherein said first means comprises in series: a first tone signal source; a first tone color means and wherein said second means comprises in series a second tone signal source; and a second tone color means.
Claim 4
Dependent Claim
63 words
The combination according to claim 1, wherein said first means comprises in series: a first tone signal source; a first tone color means and wherein said second means comprises in series; a second tone signal source; and a second tone color means different from said first tone color means, said second tone signal source being harmonically related to said first tone signal source.
Claim 5
Dependent Claim
63 words
The combination according to claim 1, wherein said first means comprises in series: a first tone signal source; a first tone color means and wherein said second means comprises in series; a second tone signal source; and a second tone color means similar to said first tone color means, said second tone signal source being harmonically related to said first tone signal source.
Claim 6
Dependent Claim
148 words
In an electronic organ system having at least two sources of octavely related tone signals and two loudspeakers, the combination comprising: a first pair of gates coupled respectively between said sources and said loudspeakers; a second pair of gates coupled respectively between said sources and said loudspeakers so that the higher frequency signal gate in said first pair is coupled to the same loudspeaker as the lower frequency signal gate in said second pair, and so that the lower frequency signal gate in said first pair is coupled to the same loudspeaker as the higher frequency signal gate in said second pair; and means for rendering said first pair of gates conductive concurrently and reiteratively and for rendering said second pair of gates conductive concurrently and reiteratively but reiteratively 180* out of phase with said first pair of gates with respect to the higher and lower frequency signals.
Claim 7
Dependent Claim
148 words
In an electronic organ system having at least two sources of octavely related tone signals and two loudspeakers, the combination comprising: a first pair of gates coupled respectively between said sources and said loudspeakers; a second pair of gates coupled respectively between said sources and said loudspeakers so that the higher frequency signal gate in said first pair is coupled to the same loudspeaker as the lower frequency signal gate in said second pair, and so that the lower frequency signal gate in said first pair is coupled to the same loudspeaker as the higher frequency signal gate in said second pair; and means for rendering said first pair of gates conductive concurrently and reiteratively and for rendering said second pair of gates conductive concurrently and reiteratively but reiteratively 180* out of phase with said first pair of gates with respect to the higher and lower frequency signals.
Claim 8
Dependent Claim
52 words

Claim 9
Independent Claim
53 words
The method of reiteratively sounding musical tones which comprises: providing at least two tone signals of different characteristics; first gating said signals separately but concurrently and reiteratively; further gating said signals separately but concurrently and reiteratively 180* out of phase with the first gated signals; and converting all the gated signals to sound.
Claim 10
Independent Claim
53 words
The method of reiteratively sounding musical tones which comprises: providing at least two tone signals of different characteristics; first gating said signals separately but concurrently and reiteratively; further gating said signals separately but concurrently and reiteratively 180* out of phase with the first gated signals; and converting all the gated signals to sound.
