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.
fig.midi.eps
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.
For details on how to make these settings, refer to “How to
Make System Settings ([MENU])” (p. 45).
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.
