This page describes how to build this full-bandwidth single-port (one input and one output) MIDI interface. The interface is buffered (that is, if the PC gets behind you won`t lose data) and it works in Windows 3.1 and Windows 95 using a special (and very well-behaved) device driver. A simpler version, using an Atmel AT89C2051 microprocessor, is described here.
MIDI input buffer size: 124 bytes
Baud rate to/from PC: 38,400 baud
Can be built using either external EPROM or single-chip processor.
Powered by PC serial port.
EPROM version may require an optiona
