Electro-Orchestra

Fictional instrument at Ma Doughty's music shop in Space City in "The Granatoids" episode (21 April 1963) of sci-fi television series Fireball XL5. Colonel Zodiac asks what it is and Prof. Matic demonstrates with a peppy tune.

It's shaped like a small grand piano except instead of keys it has 18 pedal-like levers. With only those keys, Matic produces bass, drums, horns, organ, and harpsichord sounds.
