Illustrated Guide to the CP1

Only Yamaha could bring so much to the stage piano:

Perfect marriage of keyboard touch and sound was possible

only thanks to our extensive knowledge and experience of

the building of acoustic pianos.

Unrivalled richness of tone is a direct product of our tireless

participation in the development of pianos for stage and

recording environments.

And against the backdrop of our continued stage-piano

production since introducing the CP70 and CP80 in the

seventies, we have remained loyal to the proud tradition of

vintage electric pianos in the recreation of their unique

sound. Achieved through uncompromising pursuit of

perfection in an instrument that surpasses the sum of its

parts, allow us to present…

Performance

In the CP1, we have recreated the unique sounds not only of acoustic pianos, vintage electric pianos, and synthesizer piano voices, but also of the

effect units, amplifiers, and other equipment commonly used with each in actual performance and recording settings. As shown below, these

instruments and devices are recreated as four different types of structural block – namely, Piano, Modulation Effect, Power Amplifier/Compressor,

and Reverb – and CP1 voices are fashioned by arranging these blocks with the instrument's customization function. Referred to as Performances,

these voices can then be optimized for the current playing environment using a common Master Equalizer, affecting the instrument as a whole.

Within these pages, you will find an introduction to the various different piano sounds, effects, and amplifiers provided by the blocks used to

configure CP1 Performances. We hope that you will find the following descriptions, diagrams, and photographs useful in gaining a deeper

appreciation of what this wonderful instrument has to offer, and in addition, that this booklet will serve as a convenient reference when using the

CP1's unique customization feature.

The CP1 Concept

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.

01-1 Acoustic Pianos

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.

Acoustic Pianos

The CFIIIS is the crowning glory of Yamaha's

concert grand piano range. Distinctive for its

rich harmonic overtones, this piano marries a

rich, deep low-mid register with clear and

bright highs.

Our insistence on sonic excellence extends

even to the soundboard, ribs, strings, bridge,

hammers, action, and pins – all of which are

manufactured in-house using state-of-the-art

production technologies. Furthermore, the

CFIIIS has been carefully designed to achieve

the best possible balance between each of

these parts while optimizing their overall

synergistic effect.

In the CP1, you will find that even the sound of

resonance between strings has been replicated

in order to recreate the luscious acoustics of

the CFIIIS. What's more, microphone pre-amps

featuring two- or three-band tone control and

perfectly tuned to the characteristics of the

CFIIIS have also been included to complete the

sound of this remarkable instrument.

Made possible through lavish application of

CFIIIS techniques and technologies,

the Yamaha S6B grand piano is produced at

the same plant, using carefully-selected parts,

and under the strictest quality and

engineering standards. Its modest size allows

for excellent overall balance,

both musically and structurally, and as a

result, this piano is perfectly suited to many

different styles of music. Delivering a warm,

deep sound, the S6B is ideal for extremely

expressive performances combining both

power and subtlety.

The rich tone of this grand piano is faithfully

reproduced in the CP1, even to the level of

resonance between strings.

In combination with this piano voice,

furthermore, you can also use a microphone

pre-amp unit with two- or three-band tone

control perfectly tuned to the S6B sound.

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.

Electric Pianos

Producing a sound that became inseparable

from the jazz, rock, and pop music of the

seventies, the Rd I is now practically

synonymous with the electric piano. Over the

years, the resonator used in this piano has

changed from stiff wire to rod or metal plate

as the hammer transitioned from felt to

rubber. Meanwhile, technological advances

in the circuits and other components used in

pre-amplifiers paved the way for many

different variations of this instrument, each

producing a sound that became symbolic of

the corresponding period. In addition to

recreating the ambiance of the Rd I pianos of

a number of different time periods, the CP1

also features two-band tone control in

combination with an auto-pan effect having

unique, natural-sounding modulation and

controllable speed and depth.

The latter half of the seventies saw remarkable progress in making instruments louder in response to the demands of the times. A child of this

period, the Rd II electric piano employed the latest advances in technology to realize a unique, brilliant sound that was free of distortion even at

high volumes. With plastic replacing wood in this instrument's action, furthermore, it was possible to achieve timbral colors that were brighter and

more suited to pop than those of the Rd I. Also in this period, piano sounds with boosted high frequencies also became increasingly popular, as

did the practice of customizing pre-amps in order to achieve this tone. In response, a number of modification kits appeared on the market. The

CP1 expertly reproduces both the clear sound of the Rd II and the brighter, harder sound achieved through Dyno-type customization of the original

pre-amp. Each of these two piano types also features two-band tone control, allowing the Rd II to sound more solid; the Dyno, more metallic.

The Pre-Amplifier unit has been provided with tone controls optimized

for each different piano type, and the following diagrams illustrate the

frequency characteristics corresponding to some typical parameter

settings.

The Hammer Stiffness parameter can be

used to make the piano sound harder or

softer in the same way as if the physical

properties of the hammers were to be

changed.

Typically occurring when an acoustic piano's

damper pedal is depressed, sympathetic

resonance can also be produced by

depressing the CP1's sustain pedal, and the

Damper Resonance Level parameter is used

to adjust the level thereof.

The Striking Position parameter is used to

reproduce the effect of moving the point at

which an electric piano's hammers strike the

resonators.

In order to allow for extremely-flexible creation of piano sounds, the

CP1's Piano Block features a wide range of sophisticated parameters for

each piano type and the associated pre-amp. What follows is an

introduction to some typical examples of parameters for acoustic and

electric piano sounds.

Sharing the limelight with the Rd pianos in

the sixties and seventies, the Wr electric

piano produced its distinctive sound by

striking flat steel-reed resonators with

hammers whose action closely resembled

that of an acoustic piano. Thanks to this

design, light playing produced a delicate

sound, while playing with force produced a

thick, heavy sound with unique distortion.

Earlier models were noted for a powerful

sound with a slightly higher level of

distortion; later models had a bright, clearly

defined tone. Both of these Wr variations can

be recreated by the CP1, as can the

pleasant-sounding distortion of this electric

piano and its unique tremolo effect. And with

three-band tone control also included, a

broad range of different sounds can be easily

configured.

The CP1 can also faithfully reproduce the piano sounds of the classic

Yamaha DX7 synthesizer. A synth produces sound by manipulating

signal waveforms using electronic circuits or digital signal

processing. Whenever this type of instrument is used as part of an

ensemble, furthermore, its line-output sound is processed using

pre-amplifier tone control in order to produce a frequency

characteristic that blends well with that of the other instruments. In

order to further enhance its synthesizer piano sounds, the CP1's

synth voices feature a tone controller capable of reproducing this

specific type of frequency characteristic.

Operating on the principle of FM tone generation, the Yamaha DX Series debuted at the beginning of the eighties as the world's first digital

synthesizers. The number of different sounds available and their sensitivity to different playing styles left musicians around the world in awe.

Singled out for particular praise and quickly finding a home in many different musical scenes were the electric piano sounds of the DX synths.

Produced by laying hard, high-order harmonic overtones that change delicately in response to touch over a warm, wide characteristic tone, this

totally new electric piano sound took to world by storm. The CP1 does not, however, limit itself to merely recreating the sounds of that time; rather,

a thicker tone more suited to today's musical scenes and optimized for highly-effective performance on a wooden keyboard can also be produced.

Small Phaser

The Small Phaser effect can be used to

reproduce the smooth, beautiful phasing

sound much loved by countless musicians

from the seventies onwards. In addition to

replicating the unique undulating nature of

this type of effect, Small Phaser is also

capable of producing a highly distinctive

distortion that can be adjusted using the

Drive parameter.

Max90, Max100

Max90 and Max100 replicate the

standard-type phasers popular with all

musicians of all levels, right up to top-flight

professionals. Max90 can be adjusted to

produce a unique distortion sound using the

Drive parameter; meanwhile, the Mode

parameter of the Max100 can be used to

recreate the modulation depth and feedback

settings distinctive of that effect.

Flanger

The Flanger modulation effect recreates

the sound and musicality of a variety of

flagship analog flanger units from the

seventies. As such, it is ideally suited to all

types of flanger-based sound creation.

Touch Wah, Pedal Wah

Touch Wah and Pedal Wah effortlessly

reproduce the acoustic and melodic

characteristics of many of the seventies'

leading filter sweep effects. All of your

wah-type effect needs – regardless of

whether filter sweeping is to be

controlled based on key velocity or

pedal operation – can be easily satisfied

using these effects.

Chorus

The Chorus modulation effect

reproduces the clear-cut, highly

adaptable sound of a synth-type

chorus unit.

D Chorus

D Chorus models the sound of the

famed rack-mounted stereo chorus unit

that soon became a standard in

recording studios following its release.

Irrespective of its soft, gentle

modulation, this effect can produce a

wide stereo sound, and it uniquely adds

brilliant harmonic overtones while

emphasizing attack.

816 Chorus

Famous for combining eight DX7s in

a single rack unit, Yamaha's TX816

featured a thick, detuned chorus

sound reproduced here by the 816

Chorus modulation effect.

Symphonic

A multi-stage chorus true to the

Yamaha tradition, Symphonic can be

used to replicate the ensemble effect of

the electronic organs and string

ensemble keyboards of the seventies.

By performing simultaneous, complex

modulation, this effect creates a

distinctive tone and sense of space that

other chorus effects cannot mimic,

deepening and widening the piano

sound in the process.

Each Modulation Effect block

contains a versatile collection of

modulation-type effects that will

prove indispensable in the

creation of piano sounds for both

stage and recording

environments. On this and the

following page, you will find a

brief introduction to each of the

available effects.

electric pianos, the 73Rd I

power-amp/speaker

combination produces a

spacious, more mellow tone.

75Rd I is an electric-piano

power amplifier that energizes

piano sounds to produce a

powerful, all-engulfing tone.

Particularly well suited to

chorus-type effects, the 78Rd II

power-amp/speaker

combination is characterized by

a clear, highly-present tone.

Capable of both power and

subtlety, the 69Wr power

amplifier enhances low-end

punch while enriching the

overall electric-piano sound.

For a higher degree of

presence, power-amplifier

77Wr adds a bright, colorful

ambience to electric piano

sounds.

Woody Room replicates a

distinctive reverb effect featured in

the Yamaha DM2000 and other

digital mixers. Producing dense,

rich reverberation, it also adds a

sense of width and depth that

work hand-in-hand to enhance the

original sound.

Room1, Room2, Stage1, Stage2

As direct descendants of the classic SPX90 and SPX1000 digital

multi-effects processors, Room1, Room2, Stage1, and Stage2 provide

standard reverb sounds for use in practically any situation.

Rich Hall, Rich Plate, Rich Room

Inheriting the audio characteristics of the ProR3 digital reverberator, the

Rich Hall, Rich Plate, and Rich Room reverb algorithms produce a natural

sounding reverberation with a smooth decay.

We hope that this brief introduction has

provided all the information

you need to start enjoying the incredible CP1

and to enrich your playing experience.

The Reverb block provides a host

of exquisite reverb algorithms

originally developed by Yamaha

for use in professional-audio

applications. Each of this block's
