About ESI M4U eX

After meticulous design and engineering, the M4U eX 8-Port USB 3.2 Gen 1 MIDI Interface with USB Hub emerges as a durable, compact, and high-quality solution for musicians and producers seeking efficient and user-friendly connectivity for their MIDI instruments and devices. This robust interface boasts an innovative automatic I/O detection system, enabling each of its eight MIDI ports to flexibly serve as either an input or an output. This versatility replaces the need for traditional MIDI interfaces and offers a range of configurations, such as eight outputs, eight inputs, or a combination thereof, all managed effortlessly and indicated by intuitive colored LEDs on the front panel.

As one of the world's first USB 3.0 MIDI interfaces, the M4U eX not only delivers unparalleled performance but also includes a built-in USB 3.0 hub with three additional connectors. This feature transforms the device into a central hub for all your MIDI and USB musical instrument devices, streamlining your setup and enhancing your creative workflow. Whether you're connecting software dongles, USB keyboards, or other peripherals, the M4U eX accommodates your needs with ease.

The class-compliant device offers the convenience of bus power, with the option of using the included DC power supply for powering additional USB devices. Compatible with Windows 7/8.1/10/11 and macOS, the M4U eX guarantees perfect timing and the lowest latency performance in its class, ensuring your recordings and performances are always precise.

For scenarios where a computer is not required, the M4U eX stands out with its standalone functionality. Various operation modes, selectable at the push of a button, allow for routing of input to output signals, merging of MIDI signals, or use as a MIDI thru box, providing unparalleled flexibility for all your musical endeavors.

For those requiring an even more extensive setup, the M4U eX is expandable, allowing multiple units to be connected to a computer simultaneously. Additionally, the larger M8U eX model is available for those needing up to 16 ports.

To jumpstart your music production, the M4U eX comes bundled with a powerful software package. Included is Cubasis LE, the compact version of Steinberg's mobile multitouch sequencer. Designed for quick and easy operation, Cubasis LE facilitates recording, editing, and mixing on-the-go, offering a professional-grade toolset right at your fingertips when connecting the M4U eX to an iPhone or iPad.

With its combination of a compact design and multiple connectivity options, the M4U eX 8-Port USB 3.2 Gen 1 MIDI Interface with USB Hub stands as a top choice for musicians who demand quality, reliability, and flexibility in their audio equipment.
