Owner’s Manual

Basic Structure

Part structure of the Tone Generator
block

The MO plays the sounds in its tone generator block in
response to MIDI messages received from external controllers
or sequencer. The MIDI messages are assigned to sixteen
independent channels, and the instrument is capable of
simultaneously playing sixteen separate Parts, via the sixteen
MIDI channels. However, the sixteen-channel limit can be
overcome by using separate MIDI “ports,” each supporting
sixteen channels.

The USB cable supports up to eight separate MIDI ports. However,
the tone generator in the MO supports only one port.

A single MIDI cable/connection cannot handle data over multiple
MIDI ports.

■

Part structure of the tone generator block in
the Voice mode

In this mode, a Voice is played using a single Part. The tone
generator block in the Voice mode receives MIDI data over a
single channel. For this reason, song data on an external
sequencer consisting of multiple MIDI channels will not play back
properly in this mode. If you are using an external MIDI sequencer
or computer to play the instrument, make sure to use the Song or
Pattern mode.

• To set the MIDI receive channel for single timbre operation (Voice

and Performance modes), use the following operation in the Utility
mode. [UTILITY]

• In the Voice mode, the instrument recognizes only data over MIDI

Port 1.

■

Part structure of the tone generator block in
the Performance mode

This mode lets you play a Performance (in which multiple Voices
or Parts are combined—in a layer, or in other configurations).
While a total of seven Parts are available in this mode (as shown
below), a maximum of four Parts can be used simultaneously.

Although this mode lets you play several Parts at the same time, all
are set to receive over the same single MIDI channel, as in the
Voice mode. For this reason, song data on an external sequencer
consisting of multiple MIDI channels will not play back properly in
this mode. If you are using an external MIDI sequencer or
computer to play the instrument, make sure to use the Song or
Pattern mode.

• To set the MIDI receive channel for single timbre operation (Voice

and Performance modes), use the following operation in the Utility

Part structure of the tone generator block in
the Song mode/Pattern mode

This mode lets you use multiple Parts and assign different Voices
to be played back for each Part. Since different MIDI channels can
be set for each Part of the tone generator block, you can use an
external MIDI sequencer to play the sounds. As illustrated below,
the sequence data of each track plays the corresponding Parts
(those having the same MIDI channel assignment) in the tone
generator block.

The MIDI Transmit Channel/Port of the Song/Pattern can be set
with the following operation.

When sounding the internal tone generator block, assign the
tracks to Transmit Port 1 and use Parts 1 – 16. Keep in mind that
data over Transmit Ports 2 or 3 cannot sound the internal tone
generator block.

The MIDI Receive Channel of the tone generator’s part can be set
with the following operation.

The Voice and related settings (volume, pan, etc.) are sounded by
the keyboard according to the Part parameters in the Mixing
settings of the current Song/Pattern and Part. Other settings such
as Controllers and Effect types correspond to the Common
parameters in the Mixing settings of the current Song/Pattern.
