Eminent-Solina Rithmix

On record

• KB6.de — Eminent Solina Rhitmix sample kit. KB6 preserved the Eminent Solina Rhitmix as a 27-sample kit, giving its combinable organ-era rhythms a route into later digital production. Source ↗

Rhythms beside the keyboard

The Serie 12 photographed by SMEM sits directly below an organ keyboard. Its two button rows name dances including Tango, Cha-Cha, Rhumba, Waltz and Rock, beside Volume and Tempo controls. Radio Bulletin’s 1971 report describes sixteen combinable rhythm sections: accompaniment assembled from preset choices, rather than a written sequence of individual drum steps. The photograph identifies one museum specimen, not every member of the family.

A drummer in the design work

Radiorama’s September 1972 article describes Eminent developing the musical component with a professional drummer, then its technicians working with SGS MOS designers. The reported chip offered eight externally selected programmes controlling twelve percussion-like sounds. That gives a specific account of musical requirements entering circuit design; it should not be silently equated with the sixteen sections in the earlier report.

The organ connection matters

The 1972 report says Rithmix was offered within an organ or as an independent element. R. Nickel’s later inspected unit, however, depends on organ connections for power, signals and control; he describes another specimen with a different socket arrangement. His suggested meanings for Pedal Start and Cancels to Organ are explicitly untested without the organ. The family’s independent option does not make every surviving module a standalone box.

Heard before specifications arrived

Radio Bulletin’s December 1969 Firato report says the Rhitmix was heard at the show but that specifications were not yet available. Its 1971 account describes the combinable sections; Billboard’s July 1972 NAMM report places a rhythm-equipped Solina organ before an American trade audience. These are successive public reports, not evidence that the photographed Serie 12 has been dated to each event.
