have the hardware to make a wire with a serial connection at one end and a midi connection at the other. i think that all i should need is a diagram showing how to wire this connector, and a driver which allows the serial
port
to accept midi information from pd and send out a signal that a midi
device
would understand.
It's not that easy... You would have to convert the +5Volts TTL signals from the serial port into a 20mA current loop for MIDI. You also would have to change a crystal in your computer (!) to get the MIDI data rate of 31.25 kBaud (which can not be achieved with a standard serial port). You also need to code a driver... In the end it's easier to get a MIDI interface that connects to the serial port. However, I could email you the needed info on how to build such a device but I think nowadays readily manufactured devices are much cheaper. I once built one in the days when a MIDI interface was around $400.... ;-)
