MIDI Solutions Quadra Merge
The MIDI Solutions Quadra Merge is a compact 4-in 2-out MIDI interface for combining your MIDI signals. 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 Quadra Merge 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. And is compatible with both the original 5V and new 3.3V MIDI specifications.
