Yamaha CP1 - Manual (Page 4)

The acoustic piano voices of the CP1 effortlessly reproduce the
distinctive sounds of Yamaha grand pianos, which are among the
best in the world. When an acoustic piano is played live as part of a
band, the sound thereof is normally picked up using a number of
microphones and then mixed in order to prevent it from being
drowned out by the other instruments. As part of this process, the
signal from the microphones is boosted using pre-amplifiers and its
frequency characteristic is adjusted using tone control in order to
realize the best possible sound for the overall ensemble. For this
reason, the acoustic piano voices of the CP1 feature microphone
pre-amp simulators that can be used to optimize the sound in the
very same way.

Each of the CP1's Piano blocks
comprises a Piano Type unit and
a perfectly suited Pre-Amplifier
unit. Whenever you choose a
piano type, therefore, the ideal
pre-amplifier for that specific
piano will be automatically
selected. Broadly-speaking, the
Piano Block replicates three
different classes of piano sound –
namely, acoustic pianos, electric
pianos, and synthesizers. The
following pages will describe the
actual piano sounds that can be
realized in each of these classes.
