A dual sine generator in the vein of old-school sound experiments, inspired by the works of Stockhausen, Daphne Oram, and Brüel & Kjær test equipment, among others.

It features two sine waves that can beat against each other or do FM through the deviation inputs, which are cross-normalled between the two channels. Deviation will accept a regular CV source, but don’t expect it to track 1V/oct especially accurately.
