A manufacturer of electronic instruments in the late '60s and '70s. RMI stood for "Rocky Mount Instruments" after its location in Rocky Mount, North Carolina USA. It was owned by the venerable Allen Organ Company and was originally opened as an R&D office. RMI ceased operations in 1982 as its piano and combo organ products were supplanted by the more advanced polyphonic synths that appeared in the late '70s. The parent company, Allen Organ, is still in business and has been a pioneer in incorporating digital circuitry into large church and theater organs, based in part on work done by RMI.
