Description

The BM-1BK Bluetooth MIDI Interface is a compact and clever solution designed to modernize your MIDI workflow by eliminating the clutter and restrictions of cables. It wirelessly connects your favorite legacy gear, like synthesizers, digital pianos, and MIDI controllers, to computers, tablets, and other Bluetooth MIDI-compatible devices. Whether you're working in a home studio, live stage environment, or mobile setup, the BM-1BK provides the flexibility and freedom to focus purely on creativity.

Thanks to its plug-and-play functionality, the BM-1 automatically pairs with nearby BLE-MIDI devices with no need for manual setup. It includes two components: a main adapter for MIDI OUT and a sub-adapter for MIDI IN, which can be used together or separately to suit a variety of gear configurations. The two parts are connected by a flexible cable and designed with different depths for easy installation even when ports are close together or vertically aligned. It draws power directly from the connected device's MIDI OUT terminal, eliminating the need for batteries or an external power supply.

Beyond basic connectivity, the BM-1BK offers several smart features. Through the free KORG BM-1 App (iOS/iPadOS), users can group up to five BM-1 units for multi-device communication, apply firmware updates, and unlock bonus content in compatible KORG apps. When paired with KORG Gadget 2 LE or KORG Module, the BM-1 unlocks extra tracks, sound programs, and scene features, enhancing your mobile music production experience. With up to a 20-meter wireless range, Bluetooth 5 support, and compatibility across macOS, iOS, iPadOS, and Windows, the BM-1BK is a modern MIDI interface built for versatile, wireless performance.
