The MIDI Solutions Merger is a 2-in 2-out MIDI Merger.
As of July 2016 it is compatible with devices that follow the 3.3V and 5V MIDI Specification and includes 2 MIDI Out ports.
The MIDI Solutions MultiVoltage Merger merges all MIDI messages appearing at its two MIDI inputs to its two MIDI outputs. All MIDI message types are merged, including System Exclusive, MIDI Clock, and MIDI Time Code messages. A fast merging algorithm ensures that all MIDI data is processed accurately with the minimal possible delay.
The Merger is MIDI-powered, and requires no batteries or power supply to operate with most MIDI products (for more information read the Power FAQs). A MIDI indicator LED lights up when the product is powered and flashes when MIDI data passes through it.

For example, if you are using a few MIDI keyboards and need to connect them to a sound module with a single MIDI input, a merger can be used to merge the keyboards' outputs to that input.
Mergers can also be used to merge System Exclusive data from sound modules back to computers running editor/librarian applications. This enables you to free up inputs of your MIDI interface which otherwise would have been used by the individual outputs of each sound module.
Another novel application for mergers is expanding the merging capabilities of MIDI patchbays that allow merging of only two MIDI inputs at a time. By connecting a patchbay's outputs to a merger and then looping the output of the merger back into the patchbay, you can effectively add more merging capabilities to the patchbay. The outboard merger can be thought of as in additional processor that is accessed simply by changing the patchbay's routing configuration.
