Roland EV-1-WL Instruction Manual

EV-1-WL Connection Guide
(Connect with the ME-90)
This guide shows you how to pair the EV-1-WL
wirelessly to the ME-90 using BLE MIDI.
“Pairing” involves registering the MIDI device that
you want to use (making the devices recognize each
other) with the EV-1-WL.
Pairing the EV-1-WL with another compatible
device lets you control that device via MIDI from the
EV-1-WL.

What is“BLE MIDI”?
“BLE MIDI” is the technology used to transmit and
receive MIDI messages wirelessly via Bluetooth® LE
standard.
This is ocially known as “MIDI over Bluetooth Low
Energy”.
* You must update the ME-90 to Ver. 1.03 or later
to use the EV-1-WL.

attached) and the EV-1-WL, and place them
nearby.
2. Hold down the pairing button on the BT-DUAL
until the Bluetooth indicator blinks rapidly.
3. Make sure that the Bluetooth indicator on the
EV-1-WL is blinking white.
If the indicator is blinking blue or is lit up white,
operate the device as shown below to make the
indicator blink white.
Blinking

and BOSSTONE STUDIO for ME-90
(iOS/Android) at the same time
When connecting at the same time, the following
two steps are required.
STEP 1: Connect the ME-90 and the EV-1-WL
STEP 2: Connect the EV-1-WL and the BOSS TONE STU-
DIO for ME-90 (iOS/Android)
1. Turn both the ME-90 and the EV-1-WL on, and
place them near each other.
2. Hold down the pairing button on the BT-DUAL
until the Bluetooth indicator blinks rapidly.
3. Make sure that the Bluetooth indicator on the
EV-1-WL is blinking white.
If the indicator is blinking blue or is lit up white,
operate the device as shown below to make the
indicator blink white.

or long-press the [Bluetooth] button on the
EV-1-WL.
4. Press the [Bluetooth] button on the EV-1-WL.
The Bluetooth indicator on the EV-1-WL rapidly
blinks white, and pairing begins.
The Bluetooth indicator on the EV-1-WL stops
blinking and remains lit when pairing is nished,
and the EV-1-WL and the ME-90 are connected.
5. Quickly press the [Bluetooth] button on the
EV-1-WL twice to change the Bluetooth indicator
to blink blue.
If the indicator remains lit in blue, the unit is
already paired to another device.
In this case, disconnect the other device or long-
press the Bluetooth button to make the indicator
blink blue.
6. Press the [Bluetooth] button on the EV-1-WL.
The unit enters pairing mode, and the Bluetooth
indicator on the EV-1-WL rapidly blinks blue.

7. On the BOSS TONE STUDIO for ME-90 app, select
“EV-1-WL+”.
The Bluetooth indicator on the EV-1-WL stops
blinking and remains lit when pairing is nished.
If connected correctly, it will be in the following
state.
BT-DUAL Bluetooth indicator Lit blue
EV-1-WL Bluetooth indicator Lit white, lit blue *
BOSS TONE STUDIO for ME-90
device name EV-1-WL+
* To make sure the EV-1-WL Bluetooth indicator is
lit both white and blue, quickly press Bluetooth
button twice. This switches the colors.

The EV-1-WL remembers the information for the last
Bluetooth device to which it was connected.
When connecting to a dierent device after connecting
to the ME-90, or when turning o the power while the
Bluetooth indicator is blinking white (not connected), or
when doing a factory reset of the EV-1-WL, the unit does
not pair automatically.
In this case, you must start from step 1 to congure
the settings.
NOTE
You cannot use the BOSS TONE STUDIO for ME-90
and the EV-1-WL Editor at the same time.
* The ME-90 and EV-1-WL are connected
automatically next time they are restarted.
To connect the BOSS TONE STUDIO for ME-90
you must perform steps 5 and 7 each time.
* If the devices do not pair after one minute has
passed, pairing mode is automatically canceled.
