• LPT2MIDI is a parallel printer port (LPT) to MIDI adapter.
• Autodesk Eagle PCB files are included.
• Uses Arduino IRQ to trigger pin reads and forwards the data to MIDI serial buffer (MIDI uses 31250 bps).
• A simple port trapping code for MS-DOS is included. This for the time being works for direct midi commands to port 330h only.
• Quickly modified version of SOFTMPU for MPU-401 compatibility.
• Tested with Roland MT-32 and Supaplex (an old MS-DOS game, requires minor modification to the code).
• Requires power through USB while operating.
