ESI M4U eX 8-Port MIDI Interface with USB 3.0 Hub
Product no: 9000-0098-2852 Bax Music Warranty: This product comes with a 3-year warranty.

General

The ESI M4U eX is a compact but powerful MIDI interface that's been kitted out with eight MIDI ports that can be used as inputs or outputs in various configurations. Since you're free to decide the set-up, the M4U eX is amazingly flexible and, what's more, the routing happens automatically and is based on the inputs/outputs that you've assigned and hooked up to other MIDI ports. Meanwhile, the LED indicators on the front panel of the interface will indicate exactly which ports are active. In addition to a MIDI interface, the M4U eX doubles as a USB 3.0 hub for iLok dongles and USB/MIDI keyboards, which pretty much transforms it into a central command console for your studio. Boasting an especially low latency, this ESI-built tool can even be set up as a standalone unit, so without the need for a computer.

Apparaat is geweldig, zeker een aanrader.
Jammer dat jullie levering nooit is aangekomen, maar gelukkig toch nog eentje kunnen scoren bij de concolega

Prima apparaat. Zonder drivers. Heb Window 11 en programmeer met Cubase.
Was even uitzoeken met het toekennen van in en out in. Moest drie keyboards verbinden en schakelen met één als hoofdkeyboard. Werkt nu perfect.
Er zijn ook goedkopere merken. Niet doen! zijn waardeloos.
Bij Bax zit je goed.

Simpel apparaat, geen drivers installeren maar de USB insteken en werken!
8 midi poorten welke als midi uit, als in kunnen worden gebruikt. Het is maar net waar de behoefte ligt.
Hij wordt gebruikt in Windows10, 64 bit met FL Studio 21 in een hybride opstelling met hardware als software synths.

Ik had deze jaren terug al moeten hebben, een verademing!
En in Goes op voorraad, dus super snel geleverd.

Goed product, zonder drivers direct te gebruiken. Ik maak gebruik van WIndows 11 en Cubase, de ESI M4U eX is direct te gebruiken binnen Cubase.

Snel geleverd door BAX, TOP!
