Chapter 9 Connecting and Using External MIDI Devices (MIDI Mode)
What is MIDI?
MIDI (Musical Instrument Digital Interface) is a
universal standard that allows for the exchange
of performance data and other information
among electronic musical instruments and
computers. Once MIDI cables are used to
connect together devices equipped with MIDI
connectors, each device can send data to, or
receive data from any of the others.
MIDI Connectors
The DR-670 is equipped with a MIDI IN
connector and MIDI OUT connector.
fig.09-01
MIDI IN
Receives data from an external MIDI device.
Connect to the MIDI OUT connector on the
external MIDI device.
MIDI OUT
Transmits the DR-670’s data. Connect to the
MIDI IN connector on the external MIDI device.
* Do not connect the MIDI IN connector directly
to the own MIDI OUT connector.
* When making a looped connection with other
MIDI devices, do not set the connected devices to
THRU (SOFT THRU). Otherwise, malfunction
could result.

MIDI Implementation Chart
In order to exchange MIDI data, the data
transmitted by the MIDI devices must be
common to both. The owner’s manuals for a
MIDI device always includes a MIDI
Implementation Chart, which allows you to
quickly check the compatibility of that
device with other devices. By comparing
the MIDI Implementation Charts of each
device you are using, you can confirm
which kinds of data can be exchanged.
* A separate publication titled “MIDI
Implementation” is also available. It
provides complete details concerning the
way MIDI has been implemented on this
unit. If you should require this publication
(such as when you intend to carry out byte-
level programming), please contact the
nearest Roland Service Center or
authorized Roland distributor.
