1. Introduction
MIDI Network Box Pro (MR-1 Pro) is an RTP-MIDI-based gateway designed by DOREMiDi,
which can be used in a local area network to connect multiple MIDI devices and computers to each
other, achieving low latency and high stability MIDI communication.
2. Appearance
❶MIDI OUT: 5Pin MIDI interface, connect to the MIDI IN interface of MIDI Device.

❸MIDI LAN: Ethernet interface, connect Ethernet equipment through network cable, such as
network router, network switch, etc.
❹DC IN 5V~9V: Product power supply port, power supply voltage 5~9VDC, use DC5.5*2.1 plug,
tip is positive and sleeve is negative.
❺MODE: Mode switch button, Long press 3 seconds to switch initiator/listener mode, Long press

IP Address
By default, the IP address is automatically obtained, and the IP address is
assigned through a router with DHCP function. It can also be set as a static
IP address

4. Steps for usage
1. Power supply: Use a 5~9VDC adapter to supply power to the product through the "DC IN"
interface.
2. Connect MIDI devices: Use a 5-pin MIDI cable to connect the MIDI IN of the MIDI device to the
MIDI OUT of the MR-1 Pro, and connect the MIDI OUT of the MIDI device to the MIDI IN of the
MR-1 Pro.
3. Connect to the local area network: Use the RJ45 network cable to connect the "MIDI LAN"
interface of the UR-1 Pro to a network router or network switch.
4. Listener Mode: Long press the mode button for 3 seconds, when the indicator light is blue, it
indicates the listener mode. The MR-1 Pro can be discovered and connected through a
computer or other terminal. The indicator light flashes when it is not connected, and the
indicator light is always on after the connection is successful. refer to "DOREMiDi Network MIDI
Configuration Manual.pdf" at www.doremidi.cn
5. Initiator Mode: Long press the mode button for 3 seconds, when the indicator light is red, it
means the initiator mode. In initiator mode, MR-1 Pro will automatically search for DOREMiDi's
RTP-MIDI devices in the local area network and actively connect. The indicator light flashes
when not connected, and the indicator light is always on when the connection is successful.
(Note: When an RTP-MIDI device (such as a computer) in the local area network sends a SysEx message to the
MR-1 Pro device, the maximum data size of each packet must not exceed 10K bytes.)
5. Configure the IP address
MR-1 Pro/UR-1 Pro obtains IP address automatically by default, which allows a router with
DHCP function to automatically assign an IP address. Users can send SysEx messages through the
RTP-MIDI network to configure MR-1 Pro/UR-1 Pro as a static IP address, the configuration steps
are as follows:
Environmental requirements: Windows 7 or newer version of Windows system, the computer and
the product to be upgraded need to be connected to the same local area network. For example, on
a Mac system, you can use software that can send SysEx messages, such as "SysEx Librarian".
1. Step 1: Refer to "DOREMiDi Network MIDI Configuration Manual.pdf" to connect the RTP MIDI
device of DOREMiDi to the LAN.
2. Step 2: Use MIDI-OX software to configure MIDI Output and MIDI Input. Mac system can use
SysEx Librarian software.

3. Step 3: Use to open "SysEx..." → enter the IP setting command → click "Send/Receive Syses"
to send the setting command
Set the IP SysEx format: the data header and tail are fixed, and the data area is the IP address.
For example, set the IP address to "192.168.1.112", as shown in the figure:
F0 00 21 5E 0E 40 01 09 02 01 06 08 00 00 01 01 01 02 F7
Data Header
192.168.001.112
Data Tail
After the setting is successful, software will receive a feedback message, as shown in the figure.
Then power on the product again, and the product will use a static IP.
Note:
In a network of multiple RTP MIDI devices, it is necessary to ensure that the IP addresses of
the devices cannot be duplicated, and the network segments of the IP addresses must be the
same. for example:
IP-1 : 192 : 168 : 001 : 112
IP-2 : 192 : 168 : 001 : 113
The two IP addresses are different, but the network segment 192: 168: 001 must be the same.

If you forget the IP address set by the product, you can press and hold the product button for
more than 10 seconds until the red light and blue light flash alternately, indicating that the
factory settings have been successfully restored. After the factory settings, the product will
automatically obtain an IP address and use the DHCP function A router can assign an IP
address to the product.
6. Introduction of typical application cases
1. Application 1: Before the computer is not needed, MR-1 Pro/UR-1 Pro can connect and
communicate through the network, set one product of them as the “Initiator”, and the
initiator can connect up to 3 listeners. As shown in the picture:

2. Application 2: One listener can communicate with multiple initiators at the same time, and can
support up to 5 initiators, as shown in the figure:
3. Application 3: After configuring the MR-1 Pro/UR-1 Pro as a static IP, you can connect the MIDI
device to the computer via an Ethernet cable, or connect two MIDI devices. It is suitable for
applications that need to extend MIDI communication. The communication distance of the
Ethernet cable can reach more than 100 meters, which is stable and has no delay.

7. Precautions
1. This product contains a circuit board.
2. Rain or immersion in water may cause the product to malfunction.
3. Do not heat, press, or damage internal components.
4. Non-professional maintenance personnel are not allowed to disassemble the product.
5. The working voltage of the product is 5VDC, using a voltage lower or exceeding this voltage
may cause the product to fail to work or be damaged.
8. Q&A
Question: The MIDI OUT/IN interface does not work.
Answer: Please make sure that the “MIDI OUT” of the product is connected to the “MIDI IN” of the
