A synth manufacturer that existed from 1975 to 1979. Although the company existed for a short period of time, it introduced several unique products that influenced later synth design. The company was founded by engineer / trumpet player Nyle Steiner and engineer Dick Parker. While Parker concentrated on the cases and packaging of the circuits, Steiner handled the circuit and instrument design. Steiner’s motivation originally for founding the company was to develop and market the EVI. However, because Steiner was unhappy with the results he got when using the EVI with synths on the market, he began developing his own synth designs to be used with the EVI. The misleadingly named Multiphonic Keyboard did not in fact output multiple control voltages. What it did do was arpeggation; it contained one of the first arpeggiators. After the company shut down in 1979, Steiner took the EVI design to Crumar, which put it into their production; later, it was produced by Akai. Steiner himself continues to build them today. None of the other products was ever produced again, although the Steiner filter has appeared as a module from several modular manufacturers, some of which Steiner himself consulted on.
