MIDI Expander for Keith McMillen Instruments

I use this MIDI expander to connect my KMI 12-Step foot controller (also recommended!) to a Roland SP sampler pad, which has the old-fashioned multi-pin MIDI input. It works seamlessly with these two devices, which were probably manufactured at least 20 years apart. Be warned that it only works with KMI controllers (or so it says, I haven't tested it with any other brand MIDI controllers).It's lightweight but sturdy and worked flawlessly right out of the box.

It works great, but seemed over priced.

It works as described, but shame on KMI for making a propriety box to decode USB to MIDI. Nickel and dime mentality.The MIDI ports on my unit are not aligned with the metal cutout holes and some wider-sheathed cables are difficult to get in and out because they rub against the edge of the metal cutout.

It's proprietary and doesn't serve a purpose without its keyboard. It wayyy overpriced. It's like 2-3 pieces of galvanished sheet metal, with a microchip and a few led lights and connection ports, for 60$. Ridiculous. They make you buy this to get the QuNexus to work on an analog synth. Think about that.

I bought this to use my Keith McMillen 12 Step with a Roland Fantom XR, it does what it is intended to do and outputs midi from the 12 step to my sound module. It's very light and there isn't much to it at all for the price. It is too bad it's proprietary to Keith McMillen products and needed just to send midi from what is a midi foot controller... it works though.

I bought this Keith McMillen MIDI Expander, with their $600 K-Board Controller, and other accessories from Keith McMillen through Amazon. I tried, unsuccessfully for weeks to get everything working, including their software Application. Never got anything to work as it was advertised. I Finally gave up and returned the useless K-Board Controller. This MIDI Expander which apparently is only for "some" McMillen products, did not work with the K-Board, supposedly their flagship controller. Happily, I did get a full refund for the K-Board, but sadly this MIDI Expander and the other proprietary accessories are unable to be used, as I am not ever likely to invest in another Keith McMillen product.

I'm using it with my circuit tracks, it sounds good but I need to understand it better

I bought QuNexus and wanted this unit to accompany it. Works perfectly.
