Essential Features for Your MIDI Studio

When you need the matrix MIDI patching of a MIDI Router, or you have outgrown a MIDI thru box or 1×1 USB MIDI interface, the MRCC 880 is what you are looking for. It has just the right number of inputs and outputs for a small desktop or live jamming rig:

  • 4x 5-pin DIN inputs, plus a shared 3.5mm MIDI TRS
  • 4x 5-pin DIN outputs, plus a shared 3.5mm MIDI TRS thru
  • 4x USB MIDI virtual Inputs and Outputs

It’s killer for DAWless jamming, but of course you can use it in the studio as a USB MIDI interface for your PC, Mac, or tablet. It’s great for playing stand-alone soft synths, or connect it to your DAW and plug-in instruments. With the dedicated routing buttons, you can choose which inputs get routed to which output(s) at any time.

User Centered Design

The MRCC 880 was designed for crowded desktop music spaces. Its narrow form factor and vertical connectors ensure the best use of valuable real estate. An anodized aluminum enclosure gives it stability and durability. It will look amazing among your favorite gear with its vintage synth style and hand-silk screened user interface. The raised and angled cheeks provide enough space for cables to pass under the 880.
