Star Instruments, based in Stafford, Connecticut, US, was owned by Norman Millard.
Four rubber rectangular pads connected to a main module with one oscillator producing pulse and sawtooth waveforms.
It also had a white noise generator, Low Frequency Oscillator (LFO) with triangle and pulse waveforms, a mixer and a low-pass filter with Resonance and Cutoff controls.
It added assignable functions, such as the ability to route the LFO in order to simultaneously modulate several parameters.
The pitch of the oscillator could set to a wide range of octaves, then fine tuned with a separate parameter.
As well as the ability to be run on batteries, the model featured 2 oscillators with no variable waveforms, a white-noise generator, as well as a sweep function, which could be used up or down to achieve a descending 'booming' sound which was used extensively in disco records of the era.
