Boss EV-1-WL Wireless MIDI Expression Pedal

Take command of your MIDI music gear with Boss EV-1-WL, the world's first wireless MIDI expression pedal. EV-1-WL provides wireless foot control for Boss products such as Eurus GS-1, Waza-Air and Katana-Air music apps on mobile devices and anything that can receive CC messages via Bluetooth MIDI. In addition, USB and MIDI TRS connectivity are on hand for wired control of computer music software and standard MIDI devices. Whether you go wireless or wired – or both at once – EV-1-WL delivers a ton of MIDI power in a compact footprint.

- Dedicated iOS/Android app for assigning MIDI CC numbers, customizing the response and more
- Powered with two AA batteries (included) or Boss PSA-series adaptor (sold separately)
Expand your performance range with Bluetooth
EV-1-WL is the ideal creative partner for the growing range of music performance hardware with Bluetooth wireless support. Use it to control pitch bend, filter and other synth functions in the Boss Eurus GS-1 guitar. Or add external footswitches to create a mini Bluetooth pedalboard for patch selection, wah/volume control and more in the Waza-Air and Katana-Air wireless guitar amp systems. EV-1-WL can also communicate wirelessly with a standard 5-pin MIDI device that has the Roland WM-1 Wireless MIDI Adaptor installed (sold separately).
Wireless MIDI control for computers and mobile devices
Pair EV-1-WL via Bluetooth with Mac computers, smartphones and tablets to interface with music apps that support remote operation with MIDI CC messages, from guitar amp simulators and effects to virtual instruments and music production software. And if you're a Windows user, you can add a Roland WM-1D dongle (sold separately) for wireless communication with EV-1-WL.
Plug and play via USB
EV-1-WL also works as a standalone USB MIDI controller for music software on Mac or Windows computers. The class-compliant interface means there are no drivers to install – simply plug in with a USB cable and configure your software as needed for external MIDI input.
Control MIDI stompboxes, multi-effects and more
With its space-saving TRS MIDI output, EV-1-WL is a powerful accessory for all types of MIDI music hardware, from effect pedals and multi-effects processors to keyboards, drum machines and beyond. Use a TRS-to-TRS cable with mini plugs (sold separately) to connect with Boss pedals equipped with TRS MIDI, including 200 series effects and the RC-5 and RC-500 Loop Stations. Or grab the Boss BMIDI-5-35 cable (sold separately) to connect with any device that has a standard 5-pin MIDI input jack.
Deep customization
The free EV-1-WL Editor app for iOS and Android devices lets you customize MIDI CC assignments for the EV-1-WL's pedal, toe switch and up to two external footswitches (sold separately). The Bluetooth, USB and TRS MIDI outputs support simultaneous operation and you can create independent control settings for each. It's also possible to set the switches for momentary or latching operation, adjust the pedal's response curve and more.

Any products shipped to Roland Corporation U.S. without a Return Authorization number shall be refused.
Roland Corporation U.S. will repair or replace this product at its sole option at no charge to you for parts or for labor within the warranty period; provided, however, that Roland Corporation U.S. reserves the right to determine whether the product is 'defective' for purposes of this Limited Warranty. This Warranty does not apply to damage to this product that occurred as a result of abuse or misuse, abnormal service or handling, battery leakage or failure, damage which may have been caused either directly or indirectly by another product, or if the product has been altered or modified in any way, or if the damage was caused by repairs or service provided or attempted by anyone other than Roland Corporation U.S. or a Roland Authorized Service Center.

Where applicable, if you qualify as a 'consumer' under the Magnuson-Moss Warranty Act, then you shall be entitled to any implied warranties allowed by law for the period of the Limited Warranty as set forth above.
