Joystick gain control for dual independent audio signals
First Claim
1. A method for simultaneously controlling the waveform amplitude information of two independent audio signals, comprising the steps of:
- a. providing two audio signal inputs originating from a multiplicity of acoustical-electrical transducer pickups that are incorporated into a picked or plucked stringed musical instrument, said two signals being different, andb. providing a joystick having two or more axes, a base and a handle, said handle being movable in relation to said base within a motion limit, and said base being mounted to said instrument'"'"'s body adjacent to the picked or plucked section of said instrument'"'"'s strings, so that said joystick'"'"'s location is more particularly described as;
i) beside the strings on the side of the body that hangs downward when the guitar is in a suspended playing position, andii) far enough away from the strings that the handle is not blocked by the nearest string when tilted fully toward it within said motion limit, andiii) close enough to the strings that a player'"'"'s picking hand can move the handle to any position within said motion limit while picking strings, andiv) approximately midway between the string bridge and the body end of the neck along an axis parallel to the strings that passes through the joystick body, andc. providing a translation means for translating the position of said joystick handle in relation to said joystick base as corresponding independent modifications of the waveform amplitude information of said individual input signals to provide two resultant independent signals,whereby the waveform amplitudes of said resultant two audio signals are independently modified, and may be simultaneously varied, by moving said joystick handle.

Abstract
A joystick control (20) mounted on the body (12) of an electric guitar (11) adjacent to the customarily picked section of the strings (16) provides convenient simultaneous independent gain control of two pickup signals. A pick may be held between the thumb and first finger of the picking hand while the joystick handle assembly (23) is manipulated by any free finger or fingers of that hand. This system allows smooth, quick, easy manual selection of two independent instrument voices, alternately or simultaneously in any proportion, with minimal disturbance to the player'"'"'s picking. Picking strings while varying the signals'"'"' volume levels can produce desirable timbre changes, swells, and tremolo.
A waveform polarity switch (19) optionally reverses the polarity of one pickup signal. When the signals are out of phase, the change in tone of their combined voice as the joystick travels is complex.

8. An audio signal waveform amplitude information control system comprising:
-
a. a musical instrument having a body, neck, bridge and strings, said instrument being of a type that is picked or plucked, b. a multiplicity of acoustical-electrical transducer pickups providing waveform information signals, said pickups being mounted on said instrument such that one pickup, the neck pickup, is mounted closer to said instrument'"'"'s neck and one pickup, the bridge pickup, is mounted closer to said instrument'"'"'s bridge, c. two waveform information signal input points passing two different audio input signals originating from said pickups, d. an amplitude control means for individually modifying waveform amplitude information of said two input signals carried by said input points, e. a joystick suitable in size to be used by a player while picking, said joystick having two or more axes, a base and a handle, said handle being movable in relation to said base within a motion limit, and said base being mounted to said instrument'"'"'s body adjacent to the picked or plucked section of said instrument'"'"'s strings, so that said joystick'"'"'s location is more particularly described as; i) beside the strings on the side of the body that hangs downward when the guitar is in a suspended playing position, and ii) far enough away from the strings that the handle is not blocked by the nearest string when tilted fully toward it within said motion limit, and iii) close enough to the strings that a player'"'"'s picking hand can move the handle to any position within said motion limit while picking strings, and iv) approximately midway between the string bridge and the body end of the neck along an axis parallel to the strings that passes through the joystick body, and f. one or more waveform information signal output points, and g. a translation means for causing the waveform amplitude information of individual signals passing from said signal input points to said signal output points to be correspondingly varied as said joystick handle is moved in relation to said joystick base, whereby the amplitude information of each of said signals is independently modified according to the rotation position of its respective joystick axis, and said signals'"'"' amplitude information may be simultaneously varied by moving said joystick handle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 20)

15. An audio signal waveform amplitude information control circuit comprising:
-
a. two audio signal input points passing two differing waveform information signals into the circuit, b. one or more waveform information signal output points passing waveform information out of the circuit, c. a joystick having two or more axes, a base and a handle, said handle being movable in relation to said base within a motion limit, and said joystick suitable in size to be positioned on the body of a picked or plucked stringed musical instrument within reach of a player'"'"'s picking hand while picking, whereby a player can move the joystick handle to any position within said motion limit while picking strings, and d. an amplitude control means for individually modifying waveform amplitude information of said two signals carried by said input points, and e. a translation means such that as said handle is moved in relation to said base, the amplitude information of said two waveform signals passing independently from said signal input points to said signal output points may be correspondingly individually varied. - View Dependent Claims (16, 17, 18, 19)
