I've built an adapter cable which connects to the DIN connectors and is brought out to header pins on a lead for plugging in an FTDI basic board (such as you would need for connecting directly to the onboard serial too).
Very simple to configure, only 4 wires needed (2 in each DIN connector). Just need to be aware that because the RX on MIDI is opto-isolated, you need to provide power to the opto (which is why there is the 4th wire in the cable - others are GND/RX/TX as expected). Also remember to configure your FTDI board for 3.3v not 5v.
Admittedly, this isn't as flexible as the 4 I/O lines, but if you only need 1 out and 1 in, shouldn't be an issue.
Can you give us some more detail? What is FTDI? At the end you only get 1 out and 1 in, right? I think we can only do a kind of UART through it.
