Analog synthesizer patch morphing and simultaneous parameter control though input devices

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.
