- Connecting to MIDI is not simply a question of pinouts. MIDI is current
- loop at a strange (to computers) baud rate. Buy a standard Macintosh
- MIDI interface dongle and use that to convert from the serial ports to
- MIDI. These dongles do the rs422 to current loop conversion and provide
- a external clock at the proper baud rate that is used to clock the
- serial port.
-
- Plenty of people have used startmidi in conjunction with libmidi to
- receive and transmit MIDI data over the serial ports. Nobody has wasted
- their time with getty.
