Korg BM-1 Bluetooth MIDI Interface

Smart music production, free from cables.

The BM-1 eliminates MIDI cable clutter, giving you more freedom to create. It connects to synthesizers, digital pianos, MIDI controllers, and other gear equipped with a standard 5-pin DIN MIDI connector, allowing MIDI messages to be sent and received wirelessly. With a communication range of up to 20 meters, the BM-1 works seamlessly with devices and computers that support Bluetooth MIDI, including Windows PCs, Macs, iPhones, iPads, and Bluetooth MIDI controllers.

Make your favorite gear wireless-ready

Instantly bring legacy MIDI gear into modern music production. Control vintage synthesizers from your DAW, connect your digital piano to a tablet, or take your newly wireless MIDI controller on stage. The possibilities are wide open.

Eliminate the hassle of connecting with MIDI cables

Without the limits of wired connections, you can stay focused on the creative side of making and performing music.

Automatic pairing with various BLE-MIDI devices

No manual setup is needed. Simply power on, and the BM-1 will detect and pair with nearby BLE-MIDI devices automatically.

Flexible connection options

The main adapter (MIDI OUT) and sub-adapter (MIDI IN) can be used together or separately to match your setup.

Group multiple MIDI devices

Using the dedicated KORG BM-1 App, you can group up to five BM-1 units to send and receive MIDI between them.

No external power supply or batteries required

The BM-1 runs on 5 V or 3.3 V power supplied via the MIDI OUT terminal of the connected device. There is no need for batteries or charging.
