MIDI Expander


Use your Keith McMillen controllers with Hardware MIDI devices!

The MIDI Expander is an accessorie for Keith McMillen products that enables you to use your KMI SoftStep, 12 Step, or QuNeo as a controller for your external MIDI hardware. The MIDI expander provides a MIDI In and a MIDI Out that show up on your computer as SoftStep MIDI Port 2.

Program your SoftStep with our easy-to-use control mapping software, plug in your MIDI rig, and you're ready to send and receive data to external MIDI hardware. This is a necessity if you would like to use your KMI controller without your computer, in standalone mode. At 4" x 1.25" x 1.25", the MIDI Expander is very compact and portable, just like your KMI controller.
