Hi Varam,
It stinks that they are out of stock, but if you look at the schematic: http://ucapps.de/mbhp/mbhp_midi_io.pdf, you only need about 10 components to make one on a vector board with just one midi in and out. You don't have to include the components for the LEDs. Then, as soon as the boards are back in stock, you can grab one.
I don't see the board files posted anywhere.
