Geometric Oscillator

An augmented version of the MuseWave. It produces vector graphics on an oscilloscope or analog plotter. The images are modified by twiddling the knobs and making adjustmens to the pattern generator (not shown in this picture).

The Geometric Oscillator consists of a set of identical cards called Quadrature Wavetable Oscillators (QWO’s), a mix bus, and a digital pattern generator. They QWOs interpret digital information from the pattern generator system, and put out analog voltages. An auxilliary input is available for modulation via analog multiplication. The outputs of the QWOs are summed together on a two-channel mix bus. The two channels represent X and Y coordinates in Cartesian space.  This can drive an oscilloscope, analog plotter, or other voltage-controlled devices.
