Full Featured Solid Midi Interface

This little Midi Box is a welcome addition to my Midi Configuration Studio needs. At first I was reluctant to purchase it because I felt it was a bit expensive for a Midi Interface... but it is worth it. Here's why Pros Excellent Build Quality, solid top grade materials and it looks good Works without the need for driver installation, so easy plug and play 8 Standard 5 Pin Midi Ports Plus 3 USB 3.0 Ports and a USB Host Port which gives me lots of options for all of my gear Automatic signal detection is great. Allows each MIDI port to work as an input or output LED Indicator Lights let you know what's going on In Standalone (without a computer) there are 3 modes with a dedicated Mode Selector, 1 Midi In to 7 Outs, MIDI thru and MIDI merge configurations You can use it as a Stand Alone or USB Host mode Ships with USB Cable and 5V Power Supply, yes they include a power supply! Cons Price but NOT really this is one well built, powerful Midi Interface that is loaded with Connection and Interface Options. I think it is worth the money for what it offers.
