They used this knowledge to create a series of robust piezo-electric pickups, and combined it with their experience in manufacturing acoustic pianos to make an electric instrument.

The CP-70 is designed for touring. The instrument's legs are detachable and can be stored in an internal lid. The harp can be detached from the key assembly, though this requires two people. An optional road case is available. The CP-70's flat top allows other keyboards and synthesisers to be stacked

Because the CP-70 uses custom-made strings, sourcing new ones can be problematic. Each iteration of the instrument used a different type of string, although some of the treble strings can be replaced with standard ones from an acoustic piano. As of 2019, there were two companies in the US supplying

The choice of piezo-electric pickups and their mounting position avoids the problems with earlier electric pianos, where magnetic pickups carried harmonic information at a particular distance on the string. The lack of a soundboard means it is difficult for the instrument to
