ESI M8UeX 8x8 USB 3.0 MIDI Interface with Standalone Merge/Thru

Professional 8-in/8-out MIDI interface delivering ultra-low latency over USB 3.0, with standalone merge and thru functionality for flexible routing without a computer. The robust metal chassis and per-port activity LEDs make it a reliable centerpiece for complex MIDI studios and live rigs.

Advantages

High-speed USB 3.0 connection ensures minimal latency and jitter, while backward compatibility with USB 2.0 preserves existing setups. Class-compliant operation on macOS and dedicated Windows drivers provide plug-and-play simplicity across platforms. Standalone mode allows merging or splitting MIDI data even when disconnected from a computer, expanding routing options. Eight independent inputs and outputs support up to 128 MIDI channels, accommodating large synthesizer arrays and outboard gear. Bus-powered operation eliminates the need for an external supply in most scenarios, with an optional DC input for power-hungry configurations.
