Specifications

Inputs

  • 5x MIDI 5-pin DIN inputs
  • 2x 3.5mm TRS MIDI inputs, each with a type A jack and a type B jack (use one jack per input); one of the two inputs is shared with a 5-pin DIN
  • 4x USB 2.0 MIDI host ports, 4 virtual input ports each
  • 1x USB Device port (PC, Mac, tablet) with 12 individually routable virtual ports, 16 channels per port = 192 channels in
  • All MIDI inputs are optically isolated

Outputs

  • 10x MIDI 5-pin DIN outputs
  • 4x 3.5mm TRS jacks (2x type A and 2x type B, thru), usable at the same time
  • 4x USB 2.0 MIDI host ports, 1 virtual output port each
  • 1x USB Device port with 12 individually routable virtual ports, 16 channels per port = 192 channels out
  • 19 output connections counting the MIDI thru jacks
  • Traditional 5V MIDI spec outputs
  • 1x Clock Out 3.5mm jack (use a mono TS cable)
  • 1x RJ45 for the optional MRCC Remote 7 or an MRCC to MRCC connection (not Ethernet)

Routing

  • 11 in x 17 out, every port routable and filtered
  • Inputs merge automatically when routed to a common output
  • Up to 255 routes per preset with the latest firmware (50 on earlier firmware)
  • Full matrix routing monitor with clock source indicators
  • MIDI routing tests for all ports and channels
  • MPE (MIDI Polyphonic Expression) devices are supported

Filters

  • Note on/off
  • CC
  • Program Change
  • Start / Stop / Continue

MIDI Effects & Mapping

  • Multiple arpeggiators
  • Keyboard splits and layers
  • Channel splitter
  • Velocity scaling and mapping (e.g., compress velocity from 0-127 to 0-100 for DX7)
  • CC mapping and scaling
  • Velocity and aftertouch can map to CCs (e.g., Volca FM CC for velocity, or for modulating synth parameters)
  • MIDI CC control of the MRCC arpeggiators and clock

Clock

  • USB host ports are for USB MIDI class compliant devices, or a USB PC keyboard for entering labels. Not all USB MIDI devices are compatible; check the MRCC USB Host Compatibility Tracker
  • MIDI input devices and sound modules that meet MIDI standards
  • Personal computer (Windows, OSX or Linux) for firmware updates only

In the Box

  • MRCC
  • International power supply with regional mains/outlet adapters
  • USB cable (type A to B)
  • Quick Start Guide

Expansion & Accessories

Accessories are sold separately.

MRCC Remote 7

  • Adds 5 routable 5-pin DIN MIDI outputs at a remote location; two of them also have 3.5mm TRS jacks (types A and B)
  • Connects with a single shielded Ethernet cable; a 10 meter (32 ft.) connector shielded CAT6A cable is included
  • Supports cable lengths up to 50 ft. The MIDI spec maximum cable length is 50 ft., so with a 50 ft. Ethernet cable do not use long MIDI cables on the Remote
  • Only one Remote 7 may be connected
  • Remote 7 outputs, like MRCC outputs 7-12, support SysEx data
  • The RJ45 jacks on the MRCC and Remote 7 are not Ethernet. DO NOT connect them to any Ethernet devices

MRCC XpandR 4x1

  • Plugs into an MRCC USB host port to add 4 routable 5-pin DIN inputs and 1 output, plus 2 shared 3.5mm TRS MIDI jacks
  • Also works as a computer MIDI interface with 4 USB MIDI virtual inputs and 1 output
  • Stand-alone 4 in to 1 out MIDI merger mode
  • USB powered, with traditional 5V MIDI spec output

MRCC 2U Rack Ears

  • Mount the MRCC in a standard 19 inch rack, in a 2U space
  • Powder coated steel; they replace the aluminum endcaps

MRCC to MRCC

  • Connect two MRCCs with a single shielded CAT6a (or better) Ethernet cable, up to 33 ft (10 m) apart, with remote output routing

MRCC Expansion Splitter

  • A custom RJ45 splitter connects 2 MRCCs and one Remote 7 (per splitter). Without the splitter you can connect 2 MRCCs together, or use a Remote 7, but not both
  • In this mode the Remote 7 ports are not individually routable; they act as MIDI thru ports for one MRCC, outputs 1-5
  • To order a splitter, ask on the Support page

Limited Warranty

  • MRCC and MRCC Remote 7: 1 year limited warranty to the original owner (or the minimum time required by law in your country) from the time you received it
  • Consumables, such as the MicroSD card and USB cable accessories: 90 day limited warranty

Specifications are subject to change.
