I can confirm it works really well. After some experimentation it seemed that it can be done after all.
The 10 dollar MIDI floorboard for the Pocket Pod :-)
In short, I used a cheap older raspberry pi and an old USB keyboard from the junkbin with faded letters and a bit of python code.

As soon as I cleaned up the code and documentation and finish the extra LED indicators electronics I'll release the code and electronics somewhere. Probably on GIT or somewhere alike.
