The MIDISport Hub 2×2 and 4×4 MIDI interfaces include a 3-port USB 3.0 powered hub. These devices offer musician and composers an easy 2×2 or 4×4 MIDI I/O, with the added versatility and convenience of their USB hub, which greatly expands connectivity options. Designed for ease of use, their bright LEDs (five in the 2×2 and nine in the 4×4) clearly show the status of MIDI information being sent and received. Both units are bus-powered when not using the hub, and the 2×2 features merge and standalone operation.
