• Before connecting the instrument to other electronic
components, turn off the power for all components. Before
turning the power on or off for all components, set all volume
levels to minimum.
• Be sure to set the volumes of all components at their minimum
levels and gradually raise the volume controls while playing the
instrument to set the desired listening level.

Handling caution
• Do not insert a finger or hand in any gaps on the instrument.

Location
• Do not place the instrument in an unstable position where it
might accidentally fall over.
• Before moving the instrument, remove all connected cables, to
prevent damage to the cables or injury to anyone who might trip
over them.
• When setting up the product, make sure that the AC outlet you
are using is easily accessible. If some trouble or malfunction
occurs, immediately turn off the power switch and disconnect
the plug from the outlet. Even when the power switch is turned
off, electricity is still flowing to the product at the minimum
level. When you are not using the product for a long time, make
sure to unplug the power cord from the wall AC outlet.

• Never insert or drop paper, metallic, or other objects into the
gaps on the panel or keyboard. This could cause physical injury
to you or others, damage to the instrument or other property, or
operational failure.
• Do not rest your weight on, or place heavy objects on the
instrument, and do not use excessive force on the buttons,
switches or connectors.
• Do not use the instrument/device or headphones for a long
period of time at a high or uncomfortable volume level, since
this can cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or
destroyed.
Always turn the power off when the instrument is not in use.
Even when the [STANDBY/ON] switch is in standby status (display is off), electricity is still flowing to the instrument at the minimum level.
When you are not using the instrument for a long time, make sure you unplug the power cord from the wall AC outlet.

Main Features
 Remarkably authentic organ sounds, piano sounds of unparalleled quality, and dynamic FM
synth sounds
YC series are equipped with a VCM Organ tone generator and VCM Rotary Speaker simulator that have been newly
developed based on Yamaha VCM (Virtual Circuitry Modeling) technology. These authentically reproduce the natural
saturation and warmth of sound that are uniquely characteristic to tonewheel organs and rotary speakers—thanks to
the meticulously accurate modeling of analog circuits. In addition, these are equipped with high-quality acoustic
piano and electric piano sounds perfected in and derived from the Yamaha CP series. It also features an FM tone
generator with 128-note polyphony for comprehensive dynamic performance.

 Weighted hammer-action keyboards suitable for playing as a piano/electric piano
The YC88’s NW-GH3 (Natural Wood Graded Hammer keyboard with synthetic ebony and ivory keytops) keyboard
reproduce a touch of grand piano by giving all keys an authentic resistance that increases from the top register to the
lower. Moreover, the YC73 features a BHS (Balanced Hammer Standard) keyboard, perfect for performing as an
electric piano.

 Design embodies high-class appearance and portability
The finely crafted design and aluminum exterior of YC series delivers both a sleek, professional appearance in a
lightweight, highly portable instrument—perfect for onstage use.

 User interface provides total intuitive control—essential for live performance
All controls required during onstage are placed in the dedicated Sections on the panel, such as Organ and Keys. This
gives you direct access to the parameters you need at any time and allows you to instantly improvise sound changes,
on the fly. In addition, the Organ Section features newly developed physical drawbars, which naturally deliver
exceptionally high playability, and even allow you to immediately check the current settings of the drawbars (with
LED indicators) when switching among different sounds (Live Set Sounds)—letting you fully concentrate on your
performance.

 Connect with other devices and expand your performance potential
Comprehensive MIDI control function and powerful Master Keyboard function make it more useful to connect and
use this instrument with software synthesizers and external MIDI devices. Moreover, the instrument has a built-in
Class Compliant USB Audio/MIDI interface, which makes for greater recording ease in home and professional
studios, as well as greater onstage performance power.

Characteristics

Normal

This curve produces velocities in direct
proportion to the strength of your keyboard
playing. This is the most common type of curve.

Soft

This curve makes it easier to produce high
velocities across the entire keyboard.

Hard

This curve makes it more difficult to produce
high velocities across the entire keyboard.

Wide

This curve accentuates your playing strength by
producing lower velocities in response to softer
playing and louder velocities in response to
harder playing. You can use this setting to
expand the dynamic range of your performances.

Fixed

This curve produces the same amount of sound
change, regardless of how hard or soft you play
the keyboard. The fixed velocity can be set from

&
The YC88/YC73 Organ Section allows you to select an organ type from the VCM Organ tone generator that faithfully
reproduces a tonewheel-type vintage organ or an FM tone generator that reproduces a transistor-type organ, and uses
physical drawbars allowing you to perform while changing the organ sound in real time. You can also adjust the detailed
parameters to create an organ sound that includes differences between individual instruments etc.

VCM Organ tone generator

The VCM Organ tone generator was developed to
faithfully reproduce the sound of a tonewheel-type
vintage organ.
VCM stands for “Virtual Circuitry Modeling™,” and is
technology that uses DSP to emulate the functions of an
analog electric circuit. This technology enables the
instrument to reproduce sound with an analog-like
depth, which cannot be reproduced by a simple digital
sound.
By applying this technology, the VCM Organ tone
generator fully reproduces the following characteristics
of a vintage organ.
• Natural, organic harmonies when playing chords—
thanks to a matrix circuit that connects the keyboard,
tone wheels, and drawbars
• Percussion sound with remarkable presence—based on
vacuum tube circuit analysis
• Key clicks and leakage sounds—based on electrical
circuit analysis
• Natural sound distortion—simulating vintage vacuum
tube pre-amplifiers
• Vibrato/Chorus effect—from scanner-based vibrato
circuitry
• Changes in frequency characteristics and drive amount
that responds dynamically to operation of the
expression pedal
Adjustment of these detailed parameters makes it
possible to accurately recreate the distinctive
characteristics of the original instruments—including all
of their specially attractive imperfections, faults and even
deterioration.

H1

This type faithfully reproduces a standard vintage
organ. It is fit for organ solos and music in which
the organ is the main instrument.

This type is characterized by its deep sound with
emphasis in the mid- to low-range tones. It is
ideal for when you want to have an edge or
presence that cuts through the rest of the band or
ensemble.

This type has a unique percussion sound.
This type works well with the drive effects, and is
suitable for playing fast passages.

This organ generates simple sine waves.

This type recreates a famous British transistor
combo organ.

This type recreates a famous Italian transistor
combo organ.

The type setting is common to both LOWER and
UPPER parts.

About Looper Delay
When the Looper Delay type (page 33) is selected, the
EFFECT Section behaves differently from normal:
• The Looper Delay effect is applied after the SPEAKER/
AMP Section. In addition, the effect of the REVERB
Section is not applied to the delay sound.
• The status of the [SELECT] button lamps have a
different meaning than normal. Pressing the
[SELECT] button alternates between the two states
(below).
All lit: The delay effect is applied to all the Organ,
Key A, and Key B Sections, and the sound you play is
added to the Looper.
All off: The delay effect is not applied to any of the
Sections, and the sound you play will not have any
Looper effect. Using this lets you effectively create a
rhythmic delay “loop” as you play, and then stop
adding to it so you can play phrases over it while the
loop continues.

YC88/YC73 Owner’s Manual

Using with External Devices

MIDI
Musical Instrument Digital Interface (MIDI) is a global
standard designed to allow performance, Voice, and
other data to be transferred between musical
instruments. As such, reliable data communication is
assured even between musical instruments and
equipment from different manufacturers.
In addition to data generated by playing the keyboard or
selecting a Live Set Sound, a wide range of other data
types can also be exchanged via MIDI. Using the
powerful functionality provided by this technology, you
can not only play other instruments using this
instrument’s keyboard and controllers, but you can also
adjust the volume or the tone of each Section and adjust
effect settings. In fact, practically all of the parameters
that can be set using the instrument’s control panel can
also be remotely controlled from another MIDI device.

MIDI Channels
MIDI data can be transmitted and received on one of
sixteen MIDI channels. Therefore, performance data
for up to sixteen different instrument parts can be
simultaneously exchanged over a single MIDI cable.
MIDI channels are very similar in nature to TV
channels, in that each TV station transmits its
broadcasts over a specific channel. Your TV, for
example, receives many different programs at the
same time from different broadcasters, and you
select which program to watch by choosing the
corresponding channel.
Weather forecast

News

In much the same way, multiple transmitting devices
in a MIDI system can each be set to send data on a
separate channel (i.e., a MIDI transmit channel),
which link with the system’s receiving devices via
MIDI cables. If a receiving device’s MIDI channel
(i.e., a MIDI receive channel) matches a MIDI
Transmit channel, the receiving device will produce
sound in response to the data sent by the
corresponding transmitting device.

EG/Filter Control Type List
You can change the expression of the sound in real time by operating the [EG FILTER] knob while playing phrases.
This list explains the control types of each EG and Filter.

EG (Envelope Generator)
EG allows you to determine how the level of the sound changes in time. This lets you to reproduce a variety of sound
characteristics of natural acoustic instruments—such as the quick attack and decay of percussion sounds, or the long
release of sustained piano sound. This instrument controls the following three characteristics with a single knob.
Attack

Determines the time which the sound reaches its maximum
level after the key is played. The lower the value, the quicker
the attack.

Decay

Determines the time it takes for the sound reaches its sustain
level (a slightly lower level than maximum). The lower the
value, the quicker the decay.

Release

Determines the time it takes for the sound decays to silence
after the key is released. The lower the value, the quicker the
release.

Level

Sustain Level

Time
Attack

Decay

Key on

Release
Key off

How these three characteristics change with a single knob operation is referred to as EG control type. This instrument has
11 types. The type can be set using the [EXIT] button + [EG FILTER] knob operation, or from the “EG Control”
(page 43).
Graphs below show how the Attack, Decay, and Release change when the knob is turned from the center (= 64) to the left
and right in each type.

EG/Filter Control Type List

Filter
Filter is a function that changes the tone of a sound by passing or only a specific frequency range and cutting signals in
other frequency ranges. This instrument controls the following two characteristics with a single knob.
Cutoff
Determines the cutoff frequency of the filter (which frequency
band signal or higher is cut), adjusting the brightness of the
sound. Higher values result in a brighter sound.

Resonance
Determines the amount of the resonance which raises the
volume around the cutoff frequency. Higher values result in a
more pronounced effect.

instrument again (page 23).

No sound is produced.

Related external equipment (e.g., amplifier,
speaker, headphones) is not properly
connected to this instrument via audio
cables.

Since this instrument has no built-in speakers,
you will need an external audio system or a set of
stereo headphones to properly monitor it
(page 22).

Power to this instrument or the connected
external audio equipment are not turned on.

Check the power to this instrument and the
connected external audio equipment are turned
on.

The volume of this instrument and the
connected external audio equipment are
turned fully down.

Adjust the volume. Use the [MASTER

tone generator will not sound even if you play
the keyboard. Set Local Control to “On”
(page 38).

MIDI volume or expression has been set to a
very low level by an external MIDI
controller.

Select other Live Set Sound. If a foot controller
has been connected to the FOOT
CONTROLLER [1]/[2] jacks, try using it to
increase the volume.

A sound continues to play
indefinitely.

Effect sounds such as delay continue.

Lower the [DEPTH] knob value, or set the
EFFECT1/2 [ON/OFF] button or the Section
[ON/OFF] switch to OFF. If another Live Set
Sound is selected during a sound continues to
play, press the currently selected Live Set Sound
button once more.

Sounds are distorted.

Effect settings are not appropriate.

Sound will be distorted depending on the effect
types and the settings. Change the effect types
and the settings.

Adjust the volume. To adjust the overall volume,
adjust the “I/O Volume” → “Output” (page 38).

Volume of this instrument and the
connected external audio source are set too
high.

Adjust the volume of the connected external
audio device, or use the INPUT [GAIN] knob of
this instrument. You can also adjust the volume
from the “I/O Volume” → “USB Audio”
(page 38).
