Basic Structure
Part structure of the tone
generator block
The MOTIF-RACK ES 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 multiple sound sources of this synthesizer (internal tone
generator and Plug-in Boards) take advantage of the three MIDI
ports included on the instrument.
n The USB cable supports up to eight separate MIDI ports. However, the MOTIF-
RACK ES supports up to three MIDI ports.
n 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. This Part is
used also when the Plug-in Voice is selected. 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 Multi mode.
n •To set the MIDI receive channel for single timbre operation (Voice and
Performance modes), use the following operation in the Utility mode.
[UTILITY] → MIDI display → BasicRcvCh
• In the Voice mode, the instrument recognizes only data over MIDI Port 1.
n The Multi-part Plug-in Board (PLG100-XG) cannot be used in the Voice mode.
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 six 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 Multi mode.
n •To set the MIDI receive channel for single timbre operation (Voice and
Performance modes), use the following operation in the Utility mode.
[UTILITY] → MIDI display→ BasicRcvCh

n The Multi-part Plug-in Board (PLG100-XG) cannot be used in the Performance
mode.
Part structure of the tone generator block in
the Multi 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.
Up to 48 Parts are provided for the Multi mode. However, the
number of Parts that are actually used is a maximum of 33, as we
will see later in the example.

These six Parts (1, 2, 3, 4, PLG1, PLG2) are reserved for use in the
Performance mode; however, only up to four of them can be used at the
same time. The Parts selected with the “PartSw” parameter (in the
[SHIFT]+[PERFORM] → select Performance → [EDIT] → Voice display)
are played.
