Developed in 2004, BRELS MIDI Editor is a free, open-source MIDI editor that allows the creation and editing of MIDI files with a simple, straightforward interface. Saved files have the smallest possible size, their entire content is editable onscreen and the exact composition length is shown and controllable by the program. Yet, preexistent files can be cleaned and filtered, removing garbage and embedded malformations made by other tools. The program presents a minimalist interface, from its installation, which just requires the extraction of the ZIP/RAR file without any modification to the system, to its commands, all shown onscreen, without menus or indirect paths.
