Featuring the popular MIDI auto detection technology that was pioneered by ESI, each of these 8 ports can either be used as a MIDI input or as a MIDI output, replacing not only regular MIDI interfaces like our previous popular legacy multi port MIDI interfaces with 4 inputs and 4 outputs, but providing also other possible configurations: for instance, you can use up to 8 outputs at a time or up to 8 inputs, or any other combination, like 6 outputs and 2 inputs. Each automatic input / output configuration is displayed via colored LEDs on the front panel.
