now im not too sure how technical some of you are but i was thinking one of these:

a Teensy ++ 2.0 could carry out the same task as the device here:

im pretty sure with the Teensy being programmable with a processor, and having a USB interface perhaps there would be a way to make a hex and wire it up to the ARP properly...or if the teensy would be capable of performing the task even.
ideas thoughts or feed back any one?
or how about one of these dev boards even:
