Overview of the WM-1/WM-1D
WM-1 (Connected to MIDI Connector)
The WM-1 is a wireless MIDI adaptor.
It is used by connecting it to a device that is equipped with MIDI
connectors.
5Direct connection between hardware products
5Stable synchronization with multiple connections
5Low 3 ms latency
MEMO
The WM-1D is required for wireless MIDI communication with a
Windows computer that does not support BLE MIDI.
Connections
Connect the WM-1 to your MIDI device’s MIDI connectors (IN, OUT).
WM-1D (Connect to USB Port)
The WM-1D is a wireless MIDI dongle.
To use it, connect it to your computer.
Other than its connectors and power supply, it has the same
performance as the WM-1 (WM-1 + USB MIDI interface).
5Direct connection between hardware products
5Stable synchronization with multiple connections
5Low 3 ms latency
5Operates on USB bus power
Connections
Connect the WM-1D to a USB port of your computer.
The WM-1/WM-1D transmits and receives MIDI messages wirelessly.
Using the WM-1/WM-1D allows wireless MIDI communication with your MIDI device, computer, tablet, or smartphone.
By using the WM-1D with a Windows computer that does not support BLE MIDI, you can also use a wireless MIDI connection on a Windows system.
What is BLE MIDI?
This is technology that uses Bluetooth LE to transmit and receive MIDI messages wirelessly.
It is ocially known as “MIDI over Bluetooth Low Energy.”

Setting the Communication Mode
About the Two Communication Modes
STANDARD Mode (BLE MIDI)
In STANDARD mode, you can connect to a Mac or smartphone
that supports BLE MIDI, or connect to the WM-1D connected to a
computer.
Up to three BLE MIDI devices can be connected to a WM-1 unit that is
in STANDARD mode. You can connect not only the WM-1D, but also a
Mac or smartphone.
STANDARD mode has two modes: STANDARD (Host) and STANDARD
(Remote).
&“Advanced Features” (p. 8)
FAST mode
In FAST mode, you can connect with a lower latency than STANDARD
mode.
One WM-1/WM-1D unit can be connected to a WM-1/WM-1D that is in
FAST mode.
NOTE
5A smartphone can’t be connected in FAST mode.
5If you’re using a Mac with FAST mode, connect using the WM-1D.
Switching the Communication Mode
Here’s how to switch between STANDARD mode and FAST mode.
1. Hold down the [MODE] switch for two seconds.
The [MODE] switches each time you long-press the switch.
WM-1 : “STANDARD (Host) ” #“FAST”
WM-1D : “STANDARD (Remote)” #“FAST”
For details on the mode and indicator color, refer to “About the
MODE Indicator” (p. 5).
About the MODE Indicator
The MODE indicator shows the state of the WM-1/WM-1D in each communication mode, as described below.

Registering the MIDI Device to Use (Pairing)
“Pairing” is the procedure of registering the MIDI device that you
want to use with the WM-1/WM-1D (authenticating the devices with
each other).
Here’s how to make settings so that MIDI data can be transmitted and
received between the WM-1/WM-1D and your MIDI device.
MEMO
5Once pairing has been completed between this unit and the
WM-1/WM-1D, the connection occurs automatically (memorized),
and there is no need to perform pairing again. In the case of Mac or
iPhone, the pairing operation is required each time.
5If you initialize an already-paired WM-1/WM-1D, you must initialize
the other WM-1/WM-1D unit (on Mac or a smartphone, remove the
device) and perform pairing again.
5When you switch the mode, pairing is cancelled.

A maximum of three BLE MIDI devices can be connected to a
WM-1/WM-1D in STANDARD (Host) mode (multi connection). The
following BLE MIDI devices can be connected: iPhone or other iOS
device, Mac, or a WM-1/WM-1D that is set to STANDARD (Remote)
mode.
For details on how to set the WM-1/WM-1D to STANDARD (Remote)
mode, refer to “Switching Between STANDARD (Host) Mode and
STANDARD (Remote) mode” (p. 8).
MEMO
5When pairing two WM-1 units in STANDARD mode, one of them
must be in STANDARD (Remote) mode.
5When using multi connection, only one unit of the same device
(iPhone, Mac) can be connected.

&“About the MODE Indicator” (p. 5)
5This unit cannot be used in combination with a BLE MIDI device made by a dierent manufacturer.
5When using wireless communication via a multi connection, there might be cases in which tempo synchronization is not stable. In this case,
decrease the number of remote devices.
5When using a multi connection, only one unit of the same device (Mac or smartphone) can be connected.

Limitations
5When using MIDI Sync, synchronization of the rst measure might not be stable depending on the DAW. In this case, insert an empty measure
at the beginning of the song to assist synchronization.
5When using this unit with a computer to which a USB 3.0 peripheral device is connected, interference might cause operation to be unstable. In
particular, instability is more likely if a USB ash drive or hard disk drive is connected. Create distance with the USB 3.0 peripheral when using
this unit.
