Expand Your Performance Range with Bluetooth

The 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 wireless mini pedalboard for patch selection, wah/volume control, and more in the Waza-Air personal guitar amp system. The EV-1-WL can also communicate wirelessly with a standard 5-pin MIDI device that has the Roland WM-1 Wireless MIDI Adaptor installed.

Wireless MIDI Control for Computers and Mobile Devices

Pair the 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 for wireless communication with the EV-1-WL.

Plug-and-Play via USB

The 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.

With its space-saving TRS MIDI output, the 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.

Or grab the BOSS BMIDI-5-35 cable to connect with any device that has a standard 5-pin MIDI input jack.
