KORGBM-1 Bluetooth MIDI Interface
1/10
Independent shopping perspective
The Korena take
KORG's BM-1 brings Bluetooth MIDI connectivity to gear with 5-pin DIN MIDI ports. Its MIDI Out and MIDI In adapters are joined by a flexible cable, helping the pair connect in tighter gear layouts. With up to 65.6 feet of unobstructed range, it can link compatible Mac, Windows, iOS, and iPadOS setups without a MIDI cable run. It draws compatible 5V or 3.3V power through MIDI Out, while the iOS/iPadOS app handles firmware updates and grouping up to five BM-1 units.
Strong match
Who this is for
- Adding Bluetooth MIDI to a 5-pin DIN synth, controller, or digital piano.
- Reducing cable runs between legacy MIDI gear and a compatible computer, iPhone, or iPad.
- Configuring a larger Bluetooth MIDI setup with up to five grouped BM-1 units.
Consider the trade-offs
When to look elsewhere
- Firmware updates and group configuration require the BM-1 app, which is available only for iOS and iPadOS.
