Taking Care of Your Digital Piano
This Williams Overture digital piano will supply you with years of musical enjoyment if you follow the suggestions
listed below.
Service and Modification
This product should be serviced by qualified service personnel when:
• The power supply cord or the plug has been damaged.
• Liquid has been spattered into the unit or the unit has been exposed to rain.
• The instrument does not appear to operate normally or exhibits a marked change in performance.
• The instrument has been dropped or the cabinet has been damaged.
Handling and Transport
• Never apply excessive force to the controls, connectors or other parts of the instrument.
• Always unplug cables by gripping the plug firmly, not by pulling on the cable.

TOUCH SENSITIVITY
The Overture offers four types of keyboard touch sensitivity settings: Standard, Soft, Hard and Fixed. These are
also known as “velocity” sensitivity settings and can help you to adjust the keyboard to your playing style.
Enter this mode by pressing the SETUP button. The display will show “tch”.
Use the qp buttons to select one of the following sensitivity types:
Standard (“Std”) is an intermediate response suitable for most styles of music, and is the default setting.
Soft (“SFt”) is the most sensitive keyboard response which permits maximum sound levels with a light touch.
Hard (“Hrd”) is a less sensitive keyboard response which requires a heavier touch to obtain maximum
sound levels.
Fixed (“no”) does not offer any touch sensitivity. Each key plays at full volume no matter how hard or soft the
piano keys are played. It is commonly used on Harpsichord and Organ voices.
BRIGHTNESS
This parameter is used to adjust the brightness of the sound for all voices. The range is from 1 to 16. The default
value is 8. Press the SETUP button until the display shows “brt”. Use the qp buttons to set the desired bright-
ness value from 1 to 16. Press the qp buttons simultaneously to recall the default value 8.

MASTER TUNING
The Overture is automatically set to standard A440 pitch when the piano is turned on. The tuning feature makes
it possible to tune the pitch of the piano over a range of +/– one semitone in +/– 64 steps.

from the standard acoustic piano. This function is also useful when using the Duet keyboard mode.
Press the SETUP button until the display shows “Oct”.
Use theqp buttons to set the desired octave shift value from -2 to +2.
Press the p and q buttons simultaneously to recall the default value of zero.
19
LAYER VOLUME BALANCE
This parameter is used to adjust the balance (relative volume) of the two voices in Layer mode.
The format of this parameter is “Layer voice volume - Master voice volume”.
The range of the balance setting is 9 – 1 (Layer voice dominant) to 1 – 9 (Master voice dominant).
The default setting of the volume is balanced as 5-5 (equal volume).
Press the SETUP button until the display shows “bLn”.
Use the q button to reduce the Layer volume while the Master volume increases,
for example 5-5, 4-6, 3-7 ……1-9.
Use the p button to increase the Layer volume while the Master volume decreases,
for example 5-5, 6-4, 7-3……9-1.

20
LOCAL MODE
“Local Mode” is a special mode that’s useful when the Overture is connected with another MIDI device or
computer. When “Local” is turned on, performance on the keyboard will play sounds from the internal piano
module while the performance messages are transmitted via MIDI out. When “Local” is turned off, performance
on the keyboard will not be sent to the internal piano sound module, but the performance messages are still
transmitted via MIDI out. It is useful when you’re using the piano as a keyboard controller for another MIDI
device or sound module. Please see the MIDI / USB section for more details.
Press the SETUP button until the display shows “Loc”.
Use the q button to turn Local off and use the p button to turn Local on. The default setting is “on.”
Note: When Local is “Off”, you can still access the Metronome.
STORE MODE
“Store Mode” defines whether user settings are restored to factory default or stored in memory.
User settings include reverb and chorus effect settings for each voice, layer voice, volume balance, touch mode
and song number.
Press the SETUP button until the display shows “Sto”.
Use the q button to turn the store feature off and use the p button to turn it on. The default setting is “off.”
Note: The 2-track recorder contents are always “nonvolatile” and will not be lost when the power is turned off.
If you want to recover the factory default settings, press and hold down both pq buttons while powering on
the piano. Please note that the 2-track recorder contents will be erased.

MIDI AND USB
MIDI stands for Musical Instrument Digital Interface. This is a world-wide standard communication interface
that enables electronic musical instruments and computers (of all brands) to communicate with each other so
that instructions and other data can pass between them. This exchange of information makes it possible to cre-
ate a system of MIDI instruments and devices that offer far greater versatility and control than is available with
isolated instruments. Whether you interface with computers, sequencers, expanders or other controllers, your
musical horizons will be greatly enhanced.
MIDI CONNECTION
MIDI IN: This terminal receives MIDI data from an external MIDI device.
MIDI OUT: This terminal transmits data from this instrument to other MIDI devices. The transmitted
data include the notes, touch velocity and pedals actions produced while playing on the piano, as well
as voice changes.
USB CONNECTION
The USB connector allows you to connect the Overture directly to your computer. It can be connected without
driver installation under the Windows XP, Vista & Mac OSX environments. The Overture will be recognized as a
“USB Audio device” to receive and transmit MIDI messages through a single USB cable (MIDI In/Out via USB).
LOCAL MODE
From a MIDI point of view, the Overture is composed of two “devices”:
• A controller transmitting data (the keyboard and pedals)
• A sound generator receiving MIDI data (the sound module)
In normal operation (Local ON, default mode), those two devices are connected together internally, allowing
the keyboard to play voices from the sound module without any external connection. When Local mode is OFF,
this internal link is disconnected. The sound module receives MIDI messages via MIDI input only, not from the
keyboard. However, the keyboard performance data is still sent to the MIDI Output. Local OFF mode is intended
to be used when both the MIDI input and output (or the USB port) of the Overture are connected to a MIDI
sequencer with a Soft Thru function.
21

MIDI CHANNELS
The Overture will output MIDI codes generated by playing the keyboard, stepping on the pedals or when
playing back recorded tracks (Note On/Off and Control Change messages).
The transmission channels are fixed as follows:
Channel 1: Keyboard, Master voice
Channel 2: Keyboard, Layer or Duet voice
Channel 3: Track 1 playback, Master voice
Channel 4: Track 1 playback, Layer or Duet voice
Channel 5: Track 2 playback, Master voice
Channel 6: Track 2 playback, Layer or Duet voice
Channel 13: Song playback, Right Hand
Channel 14: Song playback, Left Hand
The Metronome is not transmitted.
The MIDI system in the Overture has 16 reception channels. Each channel is responsible for a voice. When
the instrument receives MIDI information from an external device, the active channel is determined by the
control message. Channel 10 is reserved for the Drums and Percussion kit. (see Drum Kit list page 25/26). All
other channels (1-9, 11-16) can be used to access the 128 General MIDI instruments and sounds included in the
sound module (GM standard). These are the same instruments that are used to create the Orchestration dem-
onstrations.
USING AN EXTERNAL SOUND GENERATOR
Connect the MIDI Out terminal of the Overture and MIDI In terminal of an external device (keyboard,
synthesizer, or sound module). The external device will respond to your playing on the keyboard. To hear the
sound from the external device through the speakers of the piano, connect the Audio Output of the external
device to the Line Input of the Overture.
USING THE OVERTURE AS A GENERAL MIDI SOUND MODULE
Connecting the MIDI Output of an external keyboard or sequencer to the MIDI Input allows you to use the
Overture as a multi-timbral sound module to play various instrument parts in addition to your piano (for
instance, Piano on Channel 1, Bass on Channel 2, Strings on Channel 3, Drums on Channel 10, etc). The
voices on each MIDI channel are selected using MIDI Program Change messages (see the General MIDI
Voice list page 24).
Note: For more information on received MIDI messages, see the MIDI implementation chart.
USING THE OVERTURE WITH A COMPUTER
Using the USB connection, you can transmit your performance to a computer to utilize advanced recording,
composing and editing available from MIDI sequencing software. MIDI music stored on the computer (such as
MIDI files) can be played back through your instrument.
Note: In this configuration, LOCAL Mode is usually turned off.

Limited Warranty
Williams provides the following limited warranty, to the original purchaser: this piano is warranted to be free from
electronic and/or structural defects in materials and workmanship for a period of one (1) year from the date of original
purchase. If this Williams piano is defective, at its option during the warranty period, subject to the terms of this limited
warranty and upon proof of purchase, Williams will either repair or replace the listed piano with a same or similar
model of equal age or newer. Any repairs or modifications must be completed by Williams and/or an authorized agent
of Williams. The warranty obligations as set forth herein shall be performed free of charge with the exception of all
delivery and shipping expenses. This limited warranty will not apply to this product in the case of misuse, abuse, neglect,
alterations, normal wear and tear or other circumstance not directly attributed to electronic and/or structural defects in
materials or workmanship. Without limiting the foregoing, this limited warranty will also be inapplicable to products
that have not been maintained or replaced in accordance with the manufacturer’s instruction, or to products from which
the serial number has been removed or altered. If covered defects are found, contact your authorized Williams dealer
with regard to the alleged defect within ten (10) days of discovery of the problem.
The foregoing repair or replacement obligation for defective products shall be the sole and exclusive remedy of this limited
warranty. All warranties including, but not limited to, the express warranty and the implied warranties of merchantability
and fitness for a particular purpose are limited to the one (1) year warranty period. Some states do not allow limitation on
how long an implied warranty lasts, so the above limitation may not apply to you. There are no express warranties beyond
those stated here. In the event that applicable law does not allow the limitation of the duration of the implied warranties to
the warranty period, then the duration of the implied warranties shall be limited to as long as is provided by applicable law.
No warranties apply after that period.
Retailer and manufacturer shall not be liable for damages based upon inconvenience, loss of use of product, loss of time,
