MIDI
Chapter 12
MIDI is the acronym for Musical Instrument Digital Interface. Which is an industry standard protocol for electronic
musical instruments to communicate with each other.

1. MIDI Channel

MIDI protocol transmits multiple channels of MIDI performance data. Each channel can be assigned its own voice.
Typical MIDI instruments can play up to 16 channels at the same time. Which is equivalent to 16 soloists.

2. MIDI Connection

The instrument can be connected to the computer via a USB cable.
Use A to B type USB cable to connect to a computer. (The type B connector connects to the piano as shown in
the figure below.) When a computer is connected, it works as a MIDI controller.
Type A Type B
(To computer) (To Piano)

3. Local Control

Local Control allows you to control whether the keyboard of main unit will trigger the internal sound engine.
Usually Local Control should be set to On. When using the instrument to record to an external sequencer or computer,
turn this setting to Off to avoid creating a MIDI loop which may result in stuck notes or "echoes".
When the instrument is connected with an external sequencer, please check this function.
