The Kenton Merge 4 can merge the data from up to 4 separate MIDI sources (e.g. Master keyboards or controllers) into a single MIDI data stream which appears at both of the MIDI out sockets. It features 4 opto-isolated MIDI inputs and 2 MIDI outputs. Built like a tank and the best brand in my opinion for midi solutions. The customer service from kenton is second to none.
