Using MIDI
The Prelude can transmit and receive performance data when 
connected to an external MIDI device, which enables the two 
devices to control each other’s performance. For example, one 
device can play or switch sounds on the other device.
MIDI stands for “Musical Instrument Digital Interface.” It is a 
universal standard for exchanging musical performance data 
among electronic musical instruments and computers.
The Prelude’s MIDI connectors allow it to transmit performance 
data to, and receive such data from other devices. You can 
use the Prelude in a wide range of ways by connecting 
external devices to these connectors.
Connection example
Before making connections with other devices, you must turn 
down the volume of all devices and turn off the power to avoid 
malfunctions or speaker damage.

MIDI provides sixteen channels, numbered 1–16. Even if two 
MIDI devices are connected, you won’t be able to select or 
play sounds on the other device unless both devices are set to 
the same MIDI channel. The Prelude is capable of receiving on 
all channels, 1–16.
If the Prelude’s BACKING TYPE [SONG] is on, MIDI channels 
1–16 will be received by “Track” 1–16.
If the Prelude’s BACKING TYPE [STYLE] is on, MIDI channels 
1–16 will be received by the “Style” Parts.
MIDI parameters other than “Local Switch” will be saved as 
soon as you exit system edit mode.
Local Switch
If the notes you play on the keyboard are sent to the sound 
generator via both of the two routes (1) and (2) as shown in 
the diagram, the notes will be duplicated or interrupted. To 
prevent this, you can disconnect route (1) by using the “Local 
Off” setting.
You should turn this setting Off if you’ve connected a MIDI 
sequencer to the Prelude.

Immediately after the power is turned on, this setting will be 
On.
