The MIDI Solutions Quadra Merge packs 4 MIDI inputs into a 4.5 in. x 2.5 in. x 1.25 in. package. All MIDI messages appearing at the 4 inputs of the Quadra Merge are merged to the output. All MIDI data types are merged, including System Exclusive and MIDI Time Code. A fast merging algorithm ensures that the MIDI data is processed with minimal delay. 

 

The Quadra Merge is MIDI-powered and requires no batteries or power supply to operate. A MIDI indicator LED lights up when the product is powered and flashes when MIDI data passes through it.
