Merge MIDI box with 4 inputs/2 outputs
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.
The Kenton Merge 4 is powered from a mains adaptor (wall wart) so you can fit and forget.
