Roland UM-ONE mk2 USB MIDI Interface

High-Performance USB MIDI Interface with Ultra-Low Latency

The Roland UM-ONE mk2 is a compact, convenient, and incredibly fast 1-in/1-out USB MIDI interface engineered for musicians, producers, and gear enthusiasts who demand flawless connectivity. Whether you are backing up vintage drum module patches, sequencing hardware synthesizers in your DAW, or turning your digital piano into a MIDI controller, this reliable all-in-one cable style interface ensures your data moves smoothly and securely without dropouts or stuck notes.

Advanced FPT Processing for Tight Timing

At the core of the UM-ONE mk2 is Roland's proprietary FPT (Fast Processing Technology). This advanced internal processing bypasses traditional data bottlenecks, offering high-throughput, ultra-low latency, and incredibly tight clock timing. No matter how dense your MIDI sequence or expression data is, this interface maintains absolute synchronization between your performance and your software.

Versatile Cross-Platform Compatibility

Equipped with an onboard COMP/TAB hardware switch, the UM-ONE mk2 easily adapts to your specific setup requirements. When set to COMP (Computer) mode, it utilizes Roland’s dedicated, high-performance drivers for optimal speed and reliability on Windows and macOS. Switching to TAB (Tablet) mode engages class-compliant operation, allowing native plug-and-play functionality with the Apple iPad (requires optional Apple Camera Connection Kit, sold separately).

Streamlined, All-In-Line Design

Forget about losing external cables or carrying bulky breakout boxes. The UM-ONE mk2 features a sleek, durable, and lightweight housing with permanently integrated 6-foot USB and 5-pin DIN MIDI cables. To simplify troubleshooting and setup monitoring, the main unit features independent, bright LED data indicators for the USB connection, MIDI Input, and MIDI Output traffic.
