MRCC XpandR 4×1 – a DIN Expander for MRCC and USB MIDI Interface 

 

  • 4x DIN Inputs, plus 1x shared 3.5MM TRS MIDI Type A
  • 1x DIN Outputs, plus 1x shared TRS MIDI Type A thru
  • 4x USB MIDI Virtual Inputs and 1x Output
  • Dual color LED to indicate Power, Mode, MIDI Input and Output activity
  • Stand-alone USB Powered MIDI Merger Mode

Need More MIDI Inputs?

 

 

When MRCC’s 6 routable DIN and TRS inputs just aren’t enough, the MRCC XpandR 4×1 adds 4x DIN Inputs (and a shared 3.5mm TRS), and 1x DIN Output (plus 3.5mm TRS thru).

Up to four XpandRs can be attached to the MRCC’s USB host ports. Inputs and the Output are routed the same way as MRCC’s USB host MIDI virtual ports. So it’s quick and easy to route XpandR’s ports; it’s like they were built-in to MRCC.

The XpandR is also a 4x Input, 1x Output USB class compliant MIDI interface for your PC, Mac, tablet, or what have you.

Or, use the Mode button to switch XpandR to a stand-alone 4 into 1 USB powered MIDI merger. In MIDI merger mode, the USB connector is only used to power the XpandR.

A two-color* indicator shows Power, Merge mode, MIDI Input and MIDI Output activity.

The MRCC XpandR 4×1 comes housed in a robust and beautiful anodized aluminum enclosure with hand-silk screened user interface, like the MRCC. A USB cable and User Guide are included.

*The final XpandR uses Blue and Red LEDs. When there is no MIDI activity, the LEDs are very DIM to avoid annoying sensitive eyes, and blink brighter when there is MIDI activity.

MIDI I/O

Ports:

  • 4x 5-Pin DIN, and 1x 3.5mm TRS (Type A) optically isolated Inputs.1
  • 1x 5-Pin DIN, and 1x 3.5mm TRS (Type A) thru Output. Traditional 5V MIDI spec for maximum compatibility with vintage gear.
  • 1x USB 2.0 Type B device port for computer connection with 4x USB MIDI virtual Inputs and 1x Output.

1 First input pair, choose one of the 2 jacks; 5-pin DIN or 3.5mm MIDI TRS Type A.

Modes:

  • MRCC DIN expander/MIDI interface mode: the XpandR will send MIDI input to one of its DIN ports to the corresponding USB MIDI virtual cable. MIDI sent to XpandR on its USB MIDI output, will send out the DIN and 3.5MM type A jacks.
  • MIDI Merge mode: power XpandR with USB*, the 4 DIN inputs will MIDI merge to the XpandR DIN and TRS jack outputs.
    *USB will only be used to power the XpandR in MIDI merge mode. 

Indicators:

  • A dim blue LED indicates power, and MRCC expansion/MIDI interface mode.
  • A flashing blue LED indicates MIDI output activity
  • A dim red LED indicates MIDI merger mode
  • A flashing red LED indicates MIDI input activity
  • Clock ticks blink the LED at a slow rate (24/1)
  • No blink for SysEx data

Remote 7 vs XpandR 4×1

 

Q: What’s the difference in I/O between MRCC Remote 7 and MRCC XpandR 4×1?
A: The MRCC Remote 7 adds 5 additional routable outputs to MRCC. These outputs are already built into MRCC. One Remote 7 per MRCC.
XpandR adds 4x DIN inputs, and one DIN output at the expense of an MRCC USB MIDI host port. Up to four XpandR’s per MRCC, using MRCC’s available USB host ports.
Q: How far away can Remote 7 and XpandR be from MRCC?
A: The Remote 7 comes with a 10M (33 foot) long Ethernet cable. The maximum cable length is about 50 feet (using short MIDI cables).
The XpandR comes with a 2M (6 foot) USB cable. The max supported USB cable length for USB 2.0 is 5M (16.5) feet.
Q: How is each device routed?
Remote 7 is routed with the MRCC “remote routing” button. Hold the remote routing button, then select the outputs to route to.
XpandR is routed using the MRCC USB host routing buttons. Select one of the four inputs, then select outputs.
Remote 7 is great for getting MIDI outputs to where you need them. And XpandR is best when you need more MIDI DIN inputs, with the additional utility of a MIDI interface and MIDI merger. Feel free to use both!
