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 IV has several functions that facilitate its use as a MIDI device or controller.

MIDI Channels
The Legato IV 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 IV 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.
While holding the Function button, 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

Multitimbral Mode
The Legato IV 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 IV 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 IV 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
While holding the Function button, 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 amountof times equivalent to the current setting, after 2 seconds of inactivity. Once 16 is reached, pressing one more time will select 1.

MIDI Panic Reset
While holding the Function button, pressing C#1 allows the user to activate Panic, which send out general MIDI reset messages such as all note off, etc. Once Panic reset has been completed, Piano will automatically exit Edit mode.

Auto Power On/Off
While holding the Function button, pressing F#2 allows the user to switch auto Power On or Off. When F#2 is first pressed, the current setting is confirmed by Piano 1 C3 playing once for On and twice for Off. Pressing F#2 again will change the setting playing Piano 1 C3 the amount of times equivalent to the new setting.
NOTE: If this function is switched on, the unit will automatically power off after 30 minutes if there is no operation, unless the demo is playing.

When modifying the settings of the Williams Legato III the following settings will be saved after you turn off the keyboard — Reverb, Chorus (for each voice), Main Volume, Layer Volume, Split Volume, MIDI Channel, Velocity Curve, Split point and Auto Power On/Off.
