Abstract
Abstract An electronic musical instrument including a first resistive surface to which a number of control signals are applied in physically spaced relation and from which variable oscillator control signals are picked up by movable contacts on the first resistive surface. Preferably, the oscillator signals are delivered to a second resistive surface so that additional movable contacts thereon can be shifted to vary the mixed oscillator signals.
