The Pianet M was manufactured by Hohner from 1977 to the early 1980s. Originally intended for home use, the Pianet was created by Hohner’s visionary designer, Ernst Zacharias, also the inventor of the Clavinet®. A series of different versions were in production from the early 1960s to the early 1980s. The Pianet M came in a wooden console with speakers for home use. Unlike earlier Pianets, the M had a built-in effects unit called the “Modulator.”

The Pianet employs foam and leather pads which stick to the tines. Depressing a key causes the sticky pad to pull on the tine, bending it upward and when it lets go, the tine vibrates. The Pianet M used a silicone activation pad, new metal composition for the tines, and passive pickups. The Pianet M is enjoying a resurgence in popularity due to the availability of replacement parts.
