Organ system for automatically producing runs of various character

Claim 2

In an electronic organ system, a first manual and a second manual, connections enabling keys played in said first manual to sound musical notes appropriate to the keys played and for supplying a potential to the same note keys and those in octave relation thereto in said second manual, and connections for the playing keys in the second manual to sound notes for the second manual keys played which receive a keying potential, a second and a third keying potential supply for said second manual, said second supply being connected to keys in said second manual for notes in the C whole tone scale, said third supply bEing connected to keys in said second manual for notes in the C whole tone scale, and means for interrupting the second or third potential supply connections when keys in the first said manual are played in the C or C whole tone scales respectively and for interrupting both the second and third potential supply connections if keys are played simultaneously in the first said manual for notes in both the C and the C whole tone scales.

Claim 3

An electronic organ system as called for in claim 1 in which said second and said third keying potential supplies are at a less potential than the first said keying potential, and in which the keying potential from any of the first, second or third potential supplies is sufficient to sound notes according to keys played in said second manual.

Claim 4

In an electronic organ system in which keys in one manual supply keying potentials from a source in response to the keys played: keyers connected to sound notes in response to said keying potentials, twelve terminals, each of said terminals being connected to a single key and all other keys octavely related thereto to receive said potential when one of the keys in its octave group is played in said manual, said terminals representing notes in the C whole tone scale and notes in the C whole tone scale, a second manual, a normally on source of keying potential for the second manual keys for the C whole tone scale, a normally on source of keying potential for the second manual keys for the C whole tone scale, means for turning off the normally on source for the second manual keys in the C whole tone scale responsive to a potential from the first said source at a terminal representative of any note in the C whole tone scale, means for turning off the normally on source for the second manual keys in the C whole tone scale responsive to a potential from the first said source at a terminal representative of any note in the C whole tone scale, means connecting said terminals to keys of like name in said second manual, and keyers connected to said second manual and adapted to sound notes in response to keys played in said second manual if the keys played in said second manual have a keying potential applied thereto from either the first said source or one of said normally on sources.

Claim 5

In an electronic organ system in which keys in one manual supply keying potentials from a source in response to the keys played: keyers connected to sound notes in response to said keying potentials, twelve terminals, each of said terminals being connected to a single key and all other keys octavely related thereto to receive said potential when one of the keys in its octave group is played in said manual, said terminals representing notes in the C whole tone scale and notes in the C whole tone scale, a second manual, a normally on source of keying potential for the second manual keys for the C whole tone scale, a normally on source of keying potential for the second manual keys for the C whole tone scale, means for turning off the normally on source for the second manual keys in the C whole tone scale responsive to a potential from the first said source at a terminal representative of any note in the C whole tone scale, means for turning off the normally on source for the second manual keys in the C whole tone scale responsive to a potential from the first said source at a terminal representative of any note in the C whole tone scale, means connecting said terminals to keys of like name in said second manual, and keyers connected to said second manual and adapted to sound notes in response to keys played in said second manual if the keys played in said second manual have a keying potential applied thereto from either the first said source or one of said normally on sources.

Claim 6

In an electrical musical instrument, a source of several octaves of electrical tone signals for the chromatic musical scale, an output system, keyers connected for supplying said tone signals individually to said output system in response to the supply of a potential of at least a certain value to said keyers individually, a manual of playing keys connected for supplying said potential to said keyers individually according to keys played when said potential is supplied individually to keys in said manual, a first source for supplying said potential, circuit means connecting said first source to the keys in said manual for notes in the C whole tone scale, a second source for supplying said potential, circuit means connecting said second source to the keys in said manual for notes in the C whole tone scale, each of the last said circuit means having means for interrupting its connection in response to the application thereto of a keying potential having a value a predetermined amount in excess of the first said keying potential but not in response to a potential at the level of the first said potential, a third source of keying potential, said third source having said potential value at a predetermined amount in excess of the first said keying potential, a second manual of playing keys, means including keys in said second manual for connecting said third source to playing keys in the first said manual in unison and those in octave relation to keys played in said second manual, circuit means connected for supplying substantially the potential supplied by each of the playing keys of the first said manual in the C whole tone scale to the interrupTing means for the connecting means for said second source and for supplying substantially the potential supplied by each of the playing keys of the first said manual in the C whole tone scale to the interrupting means for the connecting means for said first source.

Claim 7

In an electrical musical instrument, a source of several octaves of electrical tone signals for the chromatic musical scale, an output system, keyers connected for supplying said tone signals individually to said output system in response to the supply of a potential of at least a certain value to said keyers individually, a manual of playing keys connected for supplying said potential to said keyers individually according to keys played when said potential is supplied individually to keys in said manual, a first source for supplying said potential, circuit means connecting said first source to the keys in said manual for notes in the C whole tone scale, a second source for supplying said potential, circuit means connecting said second source to the keys in said manual for notes in the C whole tone scale, each of the last said circuit means having means for interrupting its connection in response to the application thereto of a keying potential having a value a predetermined amount in excess of the first said keying potential but not in response to a potential at the level of the first said potential, a third source of keying potential, said third source having said potential value at a predetermined amount in excess of the first said keying potential, a second manual of playing keys, means including keys in said second manual for connecting said third source to playing keys in the first said manual in unison and those in octave relation to keys played in said second manual, circuit means connected for supplying substantially the potential supplied by each of the playing keys of the first said manual in the C whole tone scale to the interrupTing means for the connecting means for said second source and for supplying substantially the potential supplied by each of the playing keys of the first said manual in the C whole tone scale to the interrupting means for the connecting means for said first source.

Claim 8

In an electrical musical instrument as called for in claim 4, an additional set of keyers connected for supplying tone signals individually to the output system in response to a keying potential supplied individually to said additional set of keyers, and circuit means including said third source of potential and said second manual connected for supplying the last said potential individually to said additional set of keyers in response to keys played in said second manual.
