Overview

A Bluetooth MIDI interface for seamless wireless control.

Cut the cables and set your creativity free with the KORG BM-1, a compact Bluetooth MIDI interface that transforms any 5-pin DIN-equipped synth, controller or digital piano into a wireless powerhouse. This versatile adapter gives musicians and producers a hassle-free way to integrate legacy gear into modern workflows — connecting seamlessly to Mac, PC, iOS and other BLE-MIDI-compatible devices. Whether you’re decluttering your studio or streamlining your live rig, the BM-1 offers latency-free wireless MIDI that eliminates setup friction and boosts performance flexibility.

Seamless Performance and Flexible Configuration

With a 65.6' communication range and automatic pairing, the BM-1 is plug-and-play simplicity at its best. The main (MIDI OUT) and sub (MIDI IN) adapters are linked via a flexible cable, allowing them to connect cleanly even on cramped gear layouts. There's no need for batteries or an external power supply — it runs directly on 5V or 3.3V MIDI power. For larger setups, the BM-1 app (iOS) enables grouping up to five BM-1 units for robust multi-device MIDI routing. This means low-latency MIDI over Bluetooth LE performance, built for real-world studio and stage demands.

Enhanced App Integration and DAW Compatibility

The BM-1 doesn’t stop at connectivity — it also enhances your software. When used with KORG Gadget 2 LE or KORG Module, you unlock additional gadgets, instruments, tracks and features for both iOS and macOS. Firmware updates are handled seamlessly via the KORG BM-1 app, keeping your interface current and reliable. Whether you're controlling instruments from your DAW, triggering modules from your tablet or expanding your MIDI rig wirelessly, the BM-1 is a compact powerhouse for modern music production.

Features

  • Eliminates MIDI cables for wireless control of synths and digital pianos
  • Automatic pairing with BLE-MIDI devices simplifies setup for faster workflow
  • Connects up to five devices via the KORG BM-1 App for grouping
  • Powered through MIDI OUT, removing the need for batteries or chargers

Set your creativity free with the BM-1 Bluetooth MIDI interface—wirelessly connect your gear and explore endless possibilities in music production and performance.
