Connect Your KMI Gear to Your Hardware Synths!

Add MIDI I/O to your Keith McMillen Instruments controller with the MIDI Expander! The KMI MIDI Expander was created by Keith McMillen Instruments for the specific purpose of hooking your SoftStep, 12 Step, QuNeo, QuNexus, or K-Mix control surface to your hardware synths and MIDI-equipped effects modules. The way it works is simple: you just attach your KMI controller to the MIDI Expander via standard USB. The MIDI Expander then converts the class-compliant MIDI data running to and from your KMI controller via a pair of conventional 5-pin MIDI ports. That's it! Connecting your KMI gear to your hardware really is that easy with a Keith McMillen Instruments MIDI Expander!

Keith McMillen Instruments MIDI Expander USB/MIDI Bridge Features:

  • The ideal way to connect your KMI control surface to your MIDI-based hardware synths and effects
  • Simple, rugged, and easy-to-use converter between class-compliant MIDI over USB to conventional 5-pin MIDI I/O
  • True plug-and-play operation — hook it up and you're ready to go
  • Completely bus powered operation means no need for extra cables and bulky power supplies
  • No computer required for operation
  • LED indicators let you easily check power connectivity as well as MIDI in and out activity
  • Only compatible with SoftStep, 12 Step, QuNeo, QuNexus, and K-Mix
  • Dimensions: 4" x 1.25" x 1.25"
  • Weight: 2.5 oz.

Super Easy Set Up

KMI gives simple instructions for setting this up. I got it running without reading them. It is really simple and functions invisibly. Of course, it should be part of the 12 Step and shouldn't have to be purchased separately. That said (grumpy old man) it works flawlessly.

Another great piece of gear from Keith McMillan!

I needed the expander to convert some gear from USB to standard MIDI and this has been a great solution. The problem I have had is with some heavy Duty MIDI cables do not plug in. I ended up having to use lighter (smaller ended) cables. However, this does not affect performance. Overall, a nice small and affordable solution.

Midi through midi cables

MalletStation is designed to send midi through a USB cable. This enables connection using a midi cable. It is small, light weight and does not require support; it hangs in the air from where it is connected at the back of the MalletStation. It does add a little more set up (power supply, etc). The name can be misleading, nothing is expanded unless you include whatever device is connected through midi.

Misleading Copy

I wish the Sweetwater description included the text from KMI's product page, "*Only compatible with SoftStep, 12 Step, QuNeo, QuNexus, and K-Mix". Instead I read misleading things like "hook your KMI SoftStep, 12 Step, QuNeo, or other control surface" and "Confirmed compatibility with SoftStep, 12 Step, QuNeo, and other KMI controllers".

Keep it real Sweetwater. Edit this product description to match the manufacturer's.

MIDI Expander

It's a great kit . Be aware that there is no two prong power cable included in case you need to use external power.
