MIDI
The Musical Instrument Digital Interface
(MIDI) is an industry-standard protocol that
enables electronic musical instruments such as
keyboards, computers, drum machines, etc. to
communicate, control and synchronize with each
other. MIDI transmissions consist of electronic
codes that communicate notes to be played, the
instrument, pitch or intensity that notes are to
be played with, and the controlling codes such
as volume, vibrato, cues and clock signals. MIDI
data can be transmitted and received either
through the USB jack or a Bluetooth connection.
The Legato III has several functions that facilitate
its use as a MIDI device or controller.
MIDI Channels
The Legato III has 16 channels numbered from
1-16. Each of the channels is responsible for
a voice. When the instrument receives MIDI
information from an external device, the active
channel is determined by the control message.
The transmission channels are fixed as follows:
Channel 1 Master voice (keyboard)
Channel 2 Split voice (keyboard)
Channel 3 Layer voice (keyboard)
Local On/Off
Turning the Local On/Off function to “Off” will
disconnect the keyboard from the internal
sound engine of the piano. The Legato III may
then be used as a MIDI controller to control
other MIDI devices or virtual instrument
software running on a computer, without
playing the sounds on the piano. Additionally,
it may be desirable to turn local playing off for
other requirements such as when using MIDI
sequencing software on your computer.
1. Press the Chorus and Reverb Buttons
together to enter the Function mode.
2. Pressing D#1 allows the user to switch
local on or off. When D#1 is first pressed
the current setting is confirmed by Piano 1
C3 playing once for on and twice for off.
Pressing D#1 again will change the setting
playing Piano 1 C3 the amount of times
equivalent to the new setting.
3. Release the Chorus and Reverb Buttons
Multitimbral Mode
The Legato III is able to receive MIDI information
on up to 16 channels simultaneously. If you
plan to use your piano with a multitrack MIDI
recording system, you can record up to 16
different parts using the Williams Legato
III voices, each played back individually
on different MIDI channels. To ensure your
recorded part is played back with the correct
voice, make sure to press the voice button first
and play your part second.
NOTE: Because the Legato III is receiving
playback information via MIDI, the currently
selected voice on the piano may not correspond
to the voice being played back.
MIDI Channel Modes
1. Press and hold the Chorus and Reverb
Buttons together to enter the Function mode.
2. Pressing A#0 allows you to change the MIDI
channel. The main piano sound will play
Piano 1 C3 the amount of times equivalent
to the current value. So if MIDI channel 5 is
selected it will play 5 times. You then press
A#0 five times to select channel 10. Piano 1
C3 will play the amount of times equivalent
to the current setting, after 2 seconds of
inactivity. Once 16 is reached, pressing one
more time will select 1.
3. Release the Chorus and Reverb Buttons to
exit the Function mode.
