ESI M4U XT : radiobomb's user review
« true plug and play usb to midi 4x4 interface »
Easy to use, plug in the usb and it installs itself on windows, providing 4 in and 4 out midi connectors that show up as midi channels which themselves have 128 channels each, allowing daisy-chain midi connection. Latency is very small. Usage indicators per channel in and out. Excellent value for money. Never crashes, very stable. Exactly what it should be. 64bit drivers available on all the os platforms.
