Device for the manual playing of electronic musical instruments. Each manual has three groups of keys respectively arranged along three tilting bars, for operation by three fingers on one hand of the player. When a key is pressed at one end, it tilts the bar on which it is mounted in one direction, and one tone is produced. If the same key is pressed at the opposite end, it tilts the bar in the opposite direction, and a different tone is produced. Special control keys or action converters include a roll positioned so that it may be operated by the thumb of the same hand which is playing the keys. Rotation of the roll by the thumb produces one control signal affecting the sound issuing from the instrument, and axial motion of the roll by the thumb produces a different control signal. Other refinements and improvements are disclosed.
A device for manually playing an electronic musical instrument comprising
A device for manually playing an electronic musical instrument comprising a first row of operating keys positioned to be selectively played by one finger of a player's hand, a second row of operating keys positioned to be selectively played by a different finger of the same hand of the player simultaneously with the playing of the keys of the first row, and an additional action converter in the form of a rotary member positioned to be moved by a thumb of said hand while two fingers of said hand are playing keys in said two rows, said rotary member being mounted for both rotary movement on an axis of rotation and axial movement along said axis, both movements being controlled by said thumb of said hand, and each row of keys being mounted on a separate tilting bar elongated in the direction of spacing of the keys in the row and mounted for tilting about a tilt axis extending in the direction of elongation.
