Reinventing the Classic MIDI Router

First we made The NDLR, an innovative Multi-part Polyphonic Arpeggiator. This time, we’ve set out to reinvent the MIDI Router. Why? Because its what we needed in our studios and there’s nothing like it!

It’s super deluxe: featuring one button routing for each physical input and output, RGB LEDs, and OLED graphical display, everything can be easily setup without a PC. Unlike devices with front and rear facing connectors, MRCC’s vertical ports are designed to have the smallest footprint, saving your desk space for more synths!

Massive MIDI I/O: 11 inputs and 17 outputs, including 5 PIN DINs, 3.5MM MIDI jacks in both flavors, 4 USB host ports, and a USB client (PC, Mac or tablet) connection with 12 MIDI ports.  With automatic merging, MIDI master clock with CV clock out, filtering and MIDI effects, and MIDI message monitoring. Our customers say they were waiting all of their life for this!

Expand and extend your outputs up to 50′ away with the MRCC Remote 7. Need even more? Connect 2 MRCC’s together with a single cable for remote routing up to 32′ (10m) apart. MRCC is Rack mountable too, with the available 2U Rack Ears. See them in our shop.

MRCC provides all the connectivity options you need. Shown here with USB MIDI devices (NDLR, NanoKontrol and KeyStep) being hosted on MRCC’s USB host ports, classic 5 PIN Din connections (Volca) and trendy 3.5MM TRS MIDI (Circuit, SQ-1, 0-Coast). Lose the dongles!

Merge and Route

User Centered Design

All  MIDI  cables plug  vertically  into the  top  panel which frees up valuable table space. The top panel graphics connect each button-jack pair so you know exactly which device you are routing or filtering.

Routing MIDI paths and configuring MIDI filters is easy with the full color LEDs and the one button per input / one button per output front panel layout.

Modern Connectivity

11 inputs and 17 outputs, including 5 PIN DINs, 3.5MM MIDI jacks (in both type A and type B flavors), 4 USB host ports (with 4 virtual USB MIDI input ports each), and a USB client (PC) connection with 12 virtual USB MIDI ports. Everything you could want for connecting MIDI gear in your studio.

Advanced Functionality

 For more advanced tasks use the graphical interface on the sharp color OLED display. Using the tabs and folders style UI with the cursor buttons and encoder makes navigation simple. Once the MRCC is configured, save it to memory for recall later.  All this with no confusing PC app.

Remote 7 final graphics render


The optional MRCC Remote provides a convenient, clean solution for getting MIDI outputs to a remote location, such as into a 19″ rack or to your keyboard stand. The Remote is connected to MRCC with a single shielded Ethernet cable, eliminating a bundle of long MIDI cables.
If you need even more ports, connect two MRCCs together!


Expand the MRCC with the MRCC Remote 7. It adds 5x routable 5 pin DIN connectors, with 2 shared 3.5MM TRS (in both A and B flavors). It comes with a 10 meter (32′) Ethernet cable to get MIDI outputs to where you need them, without a bunch of long MIDI cables.

Rack mount the MRCC with 2U Rack Ears. These strong, powder coated steel rack ears mount the MRCC in a standard 19-inch rack.

*Accessories sold separately.

Delivery Status

MRCCs and accessories are shipping now. We make regular firmware updates to enhance features and fix reported issues. Update to the latest firmware before you spend a lot of time setting up your MIDI routing. Find the latest firmware on the Downloads page.

  • Dims: 15.5” x 3.5″ x 1.9″
  • 28 routing buttons, plus remote routing button and stand-by button
  • Color OLED Screen
  • Encoder and navigation buttons
  • Power switch
  • Recessed firmware update button

Physical Input/Output: 

  • 5x MIDI 5-Pin DIN Inputs
  • 2 jack selectable 3.5MM TRS  MIDI (type A and B) input (shared with 1x 5 pin DIN), choose 1 of the 3
  • 2 jack selectable 3.5MM TRS MIDI input (MIDI type A and B) choose 1 of the 2
  • All MIDI Inputs are optically isolated, and traditional 5V MIDI spec Outputs
  • 4x USB 2.0 USB MIDI Host ports (4 virtual ports per In and 1 per Out)
  • 1x USB Device port for connecting to a PC or tablet. With 12 individually routable USB MIDI virtual I/O ports (16 channels per port = 192 channels in and out).
  • 10x MIDI 5-Pin DIN Outputs
  • 4x 3.5MM TRS (2x type A and 2x type B, thru) can be used simultaneously
  • 1x Clock Out 3.5MM jack (use a mono (TS) cable)

Limited Warranty:

MRCC comes with a limited warranty to the original owner for 1 year (or the minimum time required by law in your country) from the time you received it.

The MicroSD card and accessories have a 90 day limited warranty.


  •  I/O – 11 in x 17 out routable and filtered MIDI ports (19 output connections counting MIDI thru ports)
  • Automatically merges Inputs, when routing to a common output.
  • Message filters – clock, note on/off, CC, prog change, & Stop/Start/Continue
  •  Mappings – velocity scaling, channel splitter mod, & 12 PC virtual cables on the PC port. Each USB host port has 4 USB MIDI virtual In cables and one out. You needed 4 Ins for The NDLR, right?
  •  Tools – Save/Load (127) presets*, MIDI routing tests for all ports and channels, & Visual MIDI monitors
    *Save up to 50 routes per preset. This may be expanded in the future, but currently you can’t route everything to everything all at once.

MRCC Remote 7


  • The available Remote 7 MIDI extender cleanly adds 5 routable MIDI outputs across the room to your keyboard rack, 19″ rack, or wherever you need them, with a single Ethernet cable
  • It adds 5x 5-Pin DIN MIDI  ports. Two of which have both 5-Pin and 3.5mm ports
  • Included with the Remote 7 is an appropriate “connector shielded” CAT6A Ethernet cable. Length 10 meters (32 ft.).
  • Supports up to 50 feet* length cable
    *MIDI Spec says max MIDI cable length is 50 ft. So if you have a 50 ft. Ethernet cable you should not use long MIDI cables on the Remote.
  • The RJ45 jacks on the MRCC and Remote 7 are not Ethernet. DO NOT connect it to any Ethernet devices
  • Only one Remote device may be connected
  • The Remote 7 outputs, like MRCC outputs 7-12, do not currently support SysEx data.

MRCC 2U Rack Ears

  • Mount the MRCC in a standard 19 inch rack, with the available MRCC 2U Rack Ears.
  • Made of steel and powder coated for longevity. Mount the MRCC in a 2U space.

In the works…

MRCC 4×1 Expansion:

  • Need more 5 pin DIN inputs? Plug the MRCC 4×1 Expansion into an MRCC USB host port to add 4x routable 5 pin DIN inputs and 1 output, plus 2 shared 3.5MM TRS MIDI jacks
  • Use it with MRCC for more routable ports, or plug it into your computer as a MIDI interface with 4 USB MIDI virtual Inputs and 1 Output, or use it stand-alone in the 4 in to 1 out MIDI merger mode.
  • Its USB powered with traditional 5V MIDI spec output.

MRCC Expansion Splitter:

  • A custom RJ45 splitter lets you connect 2 MRCC’s and one Remote 7 (per splitter) together. Without the splitter, you can connect 2 MRCC’s together, or use a Remote 7 but not both.
  • In this mode, the Remote 7 ports are not individually routable, but act as MIDI thru ports for one MRCC, Outputs 1-5.
