said knob comprising a drive system, a shaft position sensor, and a potentiometer; wherein said controller rotates at least one knob by generating instructions to said drive system; said at least one switch comprising an electronic connection to said controller to turn on or off said switch upon receiving instructions from said controller; and at least one patch connection, comprising at least one patch switch, wherein said at least one patch switch controls connection between at least one input of said patch and at least one output of said patch; and a control system to interpolate the potentiometer, switch and patch connections between at least two predetermined settings. ## Claims ### Claim 1 A sound generating analog synthesizer comprising a controller electronically connected to rotate at least one knob, actuate at least one switch, and make at least one patch connection; said knob comprising a drive system, a shaft position sensor, and a potentiometer; wherein said controller rotates at least one knob by generating instructions to said drive system; said at least one switch comprising an electronic connection to said controller to turn on or off said switch upon receiving instructions from said controller defining a switch position; and at least one patch connection, comprising at least one patch switch, wherein said at least one patch switch controls a connection between at least one input of said patch and at least one output of said patch; and a control system to interpolate the potentiometer, the switch position and the at least one patch connection between at least two predetermined settings. ### Claim 2 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can sense the potentiometer, switch positions and patch connections whether they are set manually or automatically. ### Claim 3 (depends on 1) The sound generating analog synthesizer of claim 1, wherein a status of the switches, knobs and patch connections is made visible on a display. ### Claim 4 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system stores all of a connection setting for each of the potentiometer, switch positions and patch connections required to create a particular sound in electronic memory so the analog synthesizer can be returned to previous state, and wherein the control system can interpolate each of the positions of the potentiometer, switch positions and patch connections between 0 and 100%. ### Claim 5 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can restore a previous state by setting the potentiometer, switch positions, and patch connections without user assistance using electromechanical and electrical devices. ### Claim 6 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can automatically set knob positions, switch states and patch connections to any setting along an interpolated path between the predetermined settings. ### Claim 7 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system changes the at least one patch connection by proportionally varying the connections between fully-on and fully-off. ### Claim 8 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can store and save to memory the predetermined settings associated with a particular sound, and wherein a recorded state to be used to define a “sound space” may be controlled through using an input device. ### Claim 9 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can be integral to the construction of the analog synthesizer, or it can be retrofitted onto an existing analog synthesizer. ### Claim 10 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the control system can be implemented as a modular synthesizer or semi-modular synthesizer. ### Claim 11 (depends on 1) The sound generating analog synthesizer of claim 1, wherein the analog synthesizer can recall the potentiometer, switch position and patch connection settings to re-create a stored sound at two or more settings on said control system, and modulate the knob, change the patch connection, and change the switch position from between 0% of a first setting to 100% of said first setting, to 0% for said second setting to 100% for said second setting. ### Claim 12 (depends on 11) The sound generating analog synthesizer of claim 11, wherein the controller can store a set of data corresponding to patch, switch, and potentiometer amounts, including their relative connectivity between 0 and 100% to save a third setting. ### Claim 13 (depends on 1) The sound generating analog synthesizer of claim 1, comprising an oscillator, keyboard or other signal generating device providing input to create a tone. ### Claim 14 A method of controlling an analog sound on a synthesizer comprising: a. generating a first sound corresponding to a first wave form, having defined a first knob and switch positions; generating a second sound corresponding to a second wave form, having a second defined knob and switch positions, wherein said first and second wave forms and first and second knob and switch positions are stored in an electronic device, said electronic device comprising a controller electronically connected to a controllable device, having electrical connection to rotate at least one knob, and actuate at least one switch; b. saving, on the controllable device, the first knob and switch positions at a first controlled position, and the second knob and switch positions at a second controlled position; c. modulating the controllable device between the first and second controlled positions; and d. interpolating the knob and switch positions between the first and second knob and switch positions as the controllable device is modulated. ### Claim 15 (depends on 14) The method of claim 14 wherein the interpolating provides for a variation between 0% and 100% between the first wave form and the second wave form. ### Claim 16 (depends on 14) The method of claim 14 comprising at least three saved wave forms. ### Claim 17 (depends on 16) The method of claim 16, wherein the interpolation between the at least three saved wave forms allows for between 0% and 100% of each wave form at any given time. ### Claim 18 (depends on 14) The method of claim 14 comprising at least four saved wave forms. ### Claim 19 (depends on 18) The method of claim 18, utilizing a joystick as the controllable device, wherein the at least four saved wave forms are positioned at different positions on an X, Y coordinate plan along the joystick's operational movement. ### Claim 20 (depends on 14) The method of claim 14 utilizing a joystick as the controllable device, wherein the first wave form and the second wave form are plotted at different points on an X, Y coordinate plan along the joystick's operational movement.
