Discontinued
The Firstman SQ-01 is a compact monophonic analog synthesizer and digital sequencer combination unit from the early 1980s. Originally released by Firstman in 1980 and later distributed by Multivox in 1981, it features a built-in 1024-note digital sequencer and a resonant low-pass filter. Only approximately 200 units were ever manufactured, making it an exceptionally rare instrument.
