Ok, I wrote something similar to that [mpe] external (btw, there's a small bug in how it handles pitch bend)
this one takes raw midi input, such as from [midiin], and gives you something you can connect directly to a [clone] object, so you can route inside it the most commonly supported mpe messages, note off, note on, aftertouch, CC 74 (aka slide) and pitch bend (aka 'glide'?).
