The instrument
When the HP-70 piano came onto the market in 1981, the era of analogue instruments was slowly coming to an end. The HP-60, released in the same year, was also analogue, while the HP-400, launched in 1983, was already digital.

The HP-70 has a keyboard with 76 keys (F1 ~ G7), the Tone Selections Piano I, Piano II, Harpsichord I, Harpsichord II, a Chorus Effect and the controls Volume, Sustain, Touch Control and Tune, and also two built-in speakers. The DP-6 sustain pedal is included.
