The KMI MIDI Expander enables you to use KMI gear such as SoftStep, 12 Step and QuNeo to control your MIDI hardware devices with 5-pin MIDI DIN connectors. Plug in your MIDI devices to the KMI MIDI Expander and you're ready to send and receive MIDI data with or without a computer.

The MIDI expander provides a MIDI In and a MIDI Out that shows up on your computer as MIDI Port 2. Program your KMI gear 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.

Your Keith McMillen Instruments controller can be powered a number of different ways when connected to a MIDI Expander. The first is to connect the Expander's POWER input to a power outlet via a USB cable and USB power adapter. The second is to connect the Expander's POWER input to a computer's USB port. The third way you can power your controller is to have the controller connected to a computer via its main USB port while it is also connected to the Expander via the Expander port (this method will not work with QuNeo as it only has one port, but will work with SoftStep and 12 Step as they have a separate Expander port).

Please note that this is not a universal USB-to-MIDI translator and works only with Keith McMillen Instruments products.
