Yamaha CP1 Brochure

Whenever an electric-piano key is played, a hammer mounted on the
keyboard strikes a resonator such as a string or reed. The vibration of the
resonator is converted into an electrical signal by a pickup, and this signal
is then amplified and adjusted to produce a sound. Featuring pre-amp units
capable of faithfully reproducing the acoustic characteristics of this
process, the electric piano voices of the CP1 authentically recreate the
sounds of the electric pianos that became so distinctive of the sixties and
seventies.
Striking its strings with an authentic grand
piano action and using pickups to convert
their vibration into an electrical signal, the
CP80 is an electric grand piano in the true
sense of the word. This instrument arrived on
the scene during the latter half of the
seventies and soon became famous for
exquisite keyboard touch rivaling that of
acoustic pianos, for fast compression-like
attack, and also for its unique harmonic
overtones. The CP80 voices reproduced in
the CP1 have been tuned to perfectly match
this instrument's keyboard. Furthermore, the
corresponding pre-amplifier unit faithfully
reproduces the three-range tone control of
the original, making it possible to easily
create a wide range of different sounds.
