A 4-knob amp-in-a-box style overdrive with ramping control over its four parameters.
Use the toggle switch below the four param knobs (drive, bass, treble, level) to assign ramping control to the LFO. Each one can be ramped up or down from the current knob position, or set to stay put.
LFO rate can be controlled by the rate knob, the tap tempo footswitch, by midi clock or by midi CC. Four waveshapes can be selected from.
Insert an expression pedal or 0-5V CV, and the LFO will stop, handing control over the ramped parameters over to the input device.
