I've built 'Adruinos' on proto board, so there no mysteries about the generic UNO circuit.
So really, speaking for myself, in addition to an AVR, the pinout/Sch and/or a Brd file. But I'm not too concerned about a Brd file, for a one off for myself. After all's said and done, to me, it's just as easy to point to point wire it as etch and drill my own.
Actually I had a dream overnight that would solve this problem.
I am going to try and fit a software serial port onto an unused GenMDM pin to handle MIDI input.
Then, for those wishing to have MIDI in from a traditional plug, you can breadboard or solder the pre-programed Teensy onto a MIDI in circuit, and simply by holding a certain other pin to ground, you can then use the software serial version and then use the MIDI input.
OR perhaps a UART. or something.
i guess my point is I had some good thoughts on it in dream mode. 
The programming is very modular and segmented, so this shouldn't be an issue.
Give me a few days to think about this, but it could be a VERY flexible solution and I'd happiy make a tutorial on how to perform this mod.
