Morph 4

A dimensional modulation array in 20 HP: four linear voltage-controlled amplifier channels driven by one master 'morph' parameter. Each channel's response to it is triangular and fully variable, its peak set by a position knob and its width by a span knob, both under voltage control, while a level input overrides it for plain VCA use; an LED bar shows each channel's response. Inputs are normalised from one channel to the next, every output has a dual-colour lamp, and combined outputs give the A+B and C+D mixes with their sum, average, minimum and maximum. A voltage-controlled mixer, dual crossfader or panner, interpolating scanner or distributor, quad VCA, quadraphonic controller, slope modifier, rectifier or complex waveshaper.
