Starting Up
Connecting to a computer
Connecting this instrument to a computer via MIDI opens up a
whole world of musical possibilities — such as using sequencer
software to record and play back compositions with the MOTIF-
RACK ES sounds or using the included Voice Editor software to
create and edit your own custom Voices.
Using an USB connector
When connecting via this method, make sure to set the following
parameter to “USB.”
n When connecting to a computer (Windows/Macintosh) via USB, make sure to
install the USB-MIDI driver to the computer as well as the desired software
(sequence software, Voice Editor, etc.). For details, refer to the separate
Installation Guide.
n Audio data cannot be transmitted or received via USB on the MOTIF-RACK ES.
Using a MIDI interface
Using the computer’s MIDI interface
Using an external MIDI interface
n Please use the appropriate MIDI interface for your computer.
n If you are using a computer that has a USB interface, make sure to connect the
computer and this synthesizer by USB. (The data transfer rate is faster than
MIDI and you’ll have access to multiple MIDI ports.)

MIDI channels and MIDI ports
While a MIDI cable can transfer MIDI messages of up to 16
channels simultaneously, a USB cable can transfer MIDI
messages of more than 16 channels simultaneously.
MIDI data is assigned to one of sixteen channels, and this
synthesizer 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. A USB cable can handle MIDI data
on up to eight ports, letting you use up to 128 channels (8 ports x
16 channels) on your computer.
By installing one Multi-part Plug-in Board and one Single-part
Plug-in Board in the MOTIF-RACK ES, you can use a
maximum of 33 Parts via USB.
n This synthesizer can recognize and use up to three ports at the same time
(page 58).
n When using a USB connection, make sure to match the MIDI transmit port
and the MIDI receive port as well as the MIDI transmit channel and the
MIDI receive channel.
