RMI Electra Piano - Combo Organs

Combo Organs

In fact, the first models produced were combo organs, including the four-octave "Explorer" (using a dedicated oscillator for each key), the "Lark", the "Band Organ" (a three-octave electrical imitation of a calliope) and the "Calliope" and "Calliope B" around 1968 or early 1969. The first electric piano model was the "Model 100 Rock-Si-Chord" in 1967. Retailing for $4695, it contained only 2 sounds (string and lute) but was later updated as the "Model 100A" which contained 5 sounds (harpsichord, cembalo, lute, Guitar A, and Guitar B). The "Model 200 Rock-Si-Chord" produced in 1968 was similar the first "Model 100", but featured an accenter option that shortened the decay of the sound. The "Model 200A" however featured twice as many sounds as the "Model 100A".
