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).

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. We supply the USB cable, you supply the USB power.
