Aside from the red status light and the fact that the device is recognized correctly on the computer, no MIDI signals through here. Neither in nor out midi ever lights up. Actually I wanted to replace my MIDISPORT 4x4 because I usually only use a MIDI device. And at the low price is not worth a return unfortunately. Apart from the fact the unit has no nameplate, CE mark or otherwise, came with no documentation, not even a sheet was there.
