Jacek Hajnrych has created a lot of programs in the Audio/MIDI area. For MIDI2DMX users we would like to recommend two free of charge applications - MIDI files player and MIDI messages monitor.
JH DMX MIDI Player
JH DMX MIDI Player is a simple application intended for playing MIDI files. Most important feature for MIDI2DMX users is dual MIDI output option of this application. Using this feature user can send selected tracks to the first MIDI output connected to other MIDI devices. Second MIDI output can be connected to MIDI2DMX converter and used for DMX devices control (lights, etc.).
