MIDI PROCESSING UNIT
MPU-IPC-T
The Roland MPU-IPC-T features the functions of the MIDI Processing Unit MPU-401 plus the interface with an IBM's
home computer. No need to say, the software such as commands and data format are exactly the same as the MPU-401.
Please read the MPU-401's Technical Reference Manual:

Warning
This equipment has been certified to comply with the limits for a Class B computing device, pursuant to Subpart J
of Part 15 of FCC Rules. Only Computer certified to comply with the Class B limits may be attached to this equip¬
ment. Operation with non-certified computing device is likely to result in interference to radio and TV reception.
Radio and Television Interference
The equipment described in this manual generates and
uses radio-frequency energy. If it is not installed and
used properly, that is, in strict accordance with our
instructions, it may cause interference with radio and
television reception.
This equipment has been tested and complies with the
limits for a Class B computing device in accordance with
the specifications in Subpart J, Part 15, of FCC rules.
These rules are designed to provide reasonable protec¬
tion against such interference in a residential installation.
However, there is no guarantee that the interference
will not occur in a particular installation, especially if
you use a "rabbit ear" television antenna. (A "rabbit ear"
antenna is the telescoping-rod type usually contained on
TV receivers.)
You can determine whether your computer is causing
interference by turning it off. If the interference stops,
it was probably caused by the computer or its peripheral
devices. To further isolate the problem:
• Disconnect the peripheral devices and their input/
output cables one at a time. If the interference stops,
it is caused by either the peripheral device or its I/O
cable. These devices usually require shield I/O cables.
For Roland peripheral devices, you can obtain the
proper shielded cable from your dealer.
If your computer or its peripheral devices does cause
interference to radio or television reception, you can try
to correct the interference by using one or more of the
following measures:
• Turn the TV or radio antenna until the interference
stops.
• Move the computer or its peripheral device to one
side or the other of the TV or radio.
• Move the computer or its peripheral devices farther
away from the TV or radio.
• Plug the computer or its peripheral devices into an
outlet that is on a different circuit than the TV or radio.
(That is, make certain the computer or its peripheral
devices and the radio or television set are on circuits
controlled by different circuit breakers or fuses.)
• Consider installing a rooftop television antenna with
coaxial cable lead-in between the antenna and TV.
If necessary, you should consult your dealer or an ex¬
perienced radio/television technician for additional
suggestions. You may find helpful the following booklet,
prepared by the Federal Communications Commission:
"How to Identify and Resolve Radio-TV Interference
Problems"
This booklet is available from the U.S. Government Printing
Office, Wasington, DC 20402, stock number 004-000-
00345-4.

■ MIDI and MPU-IPC-T
There are various ways of producing music by using
computers. For example, a computer may play music
data with its own sound source, and a robot may play
the keyboard instead of a man. The most common
method of creating computer music, however, is playing
the electronic musical instruments featuring MIDI by
a host computer. MIDI (Musical Instruments Digital
Interface) is an international standard for digitally com¬
municating musical information (e.g. pressing keys, using
bender, etc.).
MIDI Processing Unit MPU-IPC-T is an interface for a
computer and MIDI instruments (sound source). The
signals used by computers and MIDI devices are both
digital but totally different languages like English and
Japanese. The MPU-IPC-T is a micro computer that
works as an interpreter of a computer and MIDI sound
modules, allowing the host computer to concentrate
specifically on the music.

Apart from the function as an interpreter, the MPU-IPC-T
features the following functions.
a. MIDI Clock Output
The MPU-IPC-T sends out MIDI clock for synchronization
with a rhythm machine through the MIDI OUT Connector.
b. Tape Sync Function
For multitrack recording, the TAPE IN and OUT Connec¬
tors can be used to synchronize the first recorded sound
with the later recorded one.
c. M etronome Function
Metronome sound can be obtained in the tempo and
time set with the computer. This is extremely useful for
recording the music played on the keyboard into the
computer. If you find the metronome sound too small,
connect a monitor amplifier to the Metronome Out Jack.
NOTE
The function of the MPU-IPC-T available differs depend¬
ing on the software used. Please read the instructions of
each software. Also, for technical details of the MPU-
IPC-T, read the 401 Technical Reference Manual (optional).

■ Setup
The MPU-IPC-T is compatible with the following com¬
puters.
IBM PC (5150)
IBM XT (5160)
IBM AT (5170)
1. Make sure that the computer is turned off.
2. Remove the top cover and securely attach the Inter¬
face Card to the Expansion Slot.
• See the user's manual of the computer.
• Be sure to tighten the screws at the upper part of
the connector board of the CPU Card.
3. C onnect the cable of the Connector Box to the CPU
Card you have attached to the computer. Here, be
sure to tighten the screws on both ends of the conec-
tor. Here, be sure to tighten the screws on both ends
of the connector.
