Connecting your computer
If you use a USB cable (commercially available) to con-
nect the USB MIDI port located on the JM-8’s rear panel
to the USB port of your computer, you’ll be able to do
the following things.
• Use the JM-8 to play SMF music files played back by
MIDI-compatible software.
• By transferring MIDI data between the JM-8 and
your sequencer software, you’ll be able to enjoy a
wide range of possibilities for music production and
editing.
(1) Use a standard USB cable (A‰B-type connectors,
commercially available) to connect the JM-8 to
your computer as shown below.
(2) Refer to the Roland website for system require-
ments.

If the computer doesn’t ‘see’ the JM-8
Normally, you don’t need to install a driver in order
to connect the JM-8 to your computer. However, if
some problem occurs, or if the performance is poor,
using the Roland original driver may solve the prob-
lem.
For details on downloading and installing the Roland
original driver, refer to the Roland website:
http://www.roland.com/
Specify the USB driver you want to use, and then
install the driver. For details, refer to page 85.

Caution
• To avoid the risk of malfunction and/or damage to
external speakers, always turn the volume all the way
down and switch off the power on all devices before
you make any connections.
• Only MIDI data can be transmitted and received via
USB. Audio data for a song recorded on the JM-8
cannot be transmitted or received.
• Switch on the power to the JM-8 before you start up
the MIDI application on your computer. Never turn
the JM-8’s power on/off while your MIDI application
is running.
MIDI synchronization
There may be times when you want to use the JM-8
together alongside an external sequencer, computer,
drum machine, etc. For this to work properly, you need
set the JM-8 to follow the tempo of the external device
to ensure that it starts and stops at the same time as
the external device.
Note: The JM-8 does not transmit system realtime data.
(1) Connect the external sequencer, etc. to the JM-8’s
MIDI IN socket (see p. 97) or USB MIDI port (see
p. 102).
Be sure to follow all instructions given in the relevant
section.
(2) Press the [EXIT] button repeatedly until it stops
flashing to return to the main page (if necessary).
(3) Press

(4) Press the
[MODE]
display field in the “SONG RX”
section and use the dial to select one of the fol-
lowing settings.
Auto: This is a good setting for remote control of
song (using a PK-5A dynamic MIDI pedal board, for
example). Whenever the JM-8 receives a MIDI Start
message (FA), it waits for Clock messages that specify
the tempo. If those Clock messages are not received
(a PK-5A, for instance, doesn’t send them), the JM-8
starts playback using its internal tempo.
If, however, Clock messages (F8) follow after the Start
message, the JM-8 uses the external tempo. You can
nevertheless go on using the SMF player/16-track
sequencer without MIDI Start/Clock messages, which
is not possible when you select “MIDI”.
Internal: The JM-8 uses its internal tempo (no syn-
chronization).
MIDI: Song can only be started or stopped with MIDI
real-time messages (Start, Stop, Clock) received from
an external clock source.
Remote: When the JM-8 receives a start message, it
will start using its own tempo. When it receives a
stop message, playback stops. External clock mes-
sages are ignored.
(5) Press the [EXIT] button repeatedly until it stops
flashing to return to the main page.
Note: If you want to use these settings again at a later
stage, consider saving them to a MIDI Set (see p. 103).
