MIDI-OX is a Windows 95/NT program (also Win98/Me/2000/XP/Vista). It is a 32 bit program which will not operate under earlier versions of Windows. MIDI-OX is a multi-purpose tool: it is both a diagnostic tool and a System Exclusive librarian. It can perform filtering and mapping of MIDI data streams. It displays incoming MIDI streams, and passes the data to a MIDI output driver or the MIDI Mapper. You can generate MIDI data using the computer keyboard or the built-in control panel. You can even record and log MIDI data and then convert it to a Standard MIDI File for playback by a sequencer. Some additional information is available in the MIDI and Audio FAQ.
