The Harmonic Synthesizer was a monophonic synthesizer[1] that was first produced in 1974 by the American Rocky Mount Instruments[2] The case was made of black vinyl and had four chrome legs to support it. It features two sets of 16 harmonic drawbars. It also had a number of effects such as tremolo, portamento, noise modulation, oscillator sync and an arpeggiator. The digital circuitry ensures tuning stability during use.[3] A total of 250 units were produced and only four units were ever sold[4] in Europe.[5]
