Roland UM-ONE MK2 USB MIDI Interface

Compact, clean, and cleverly designed, the Roland UM-ONE MK2 is the kind of unsung hero that quietly holds the studio together. Whether you're a home producer, a live performer, or a mobile music-maker working off your iPad, this interface ensures your MIDI data gets where it needs to go—fast, reliably, and with rock-solid timing.

Unlike bulky interfaces that demand extra desk space or power adapters, the UM-ONE MK2 takes a more elegant approach. It features a tidy in-line design with integrated MIDI and USB leads—no fuss, no clutter. Just plug in and go. With one MIDI in and one MIDI out, it supports up to 16 channels in each direction, making it perfect for everything from synths and drum machines to controllers and outboard sequencers.

But the real trick up its sleeve is Roland’s ultra-low-latency processing, which ensures tight timing and snappy responsiveness. Whether you're layering MIDI drums or sending clock signals to your gear, it performs with the kind of accuracy that keeps everything in lockstep.

And it’s not just for laptops. The UM-ONE MK2 is fully compatible with Mac and Windows machines, and it even works with iPads (via the Apple Camera Connection Kit), making it a dream for mobile setups and fly dates. With simple LED indicators and bus-powered convenience, it’s the type of tool you’ll forget is even there—until the day you try to work without it.
