dmidiplayer

DMidiPlayer is a multiplatform MIDI file player built around the Drumstick libraries, allowing users to playback standard musical instrument digital interface sequences on Linux systems. Created by Pedro López-Cabanillas and published under the GPL-3.0-or-later license, the application interfaces with hardware synthesizers, software soundfonts, and ALSA or OSS MIDI ports. It provides transport controls, tempo adjustments, and track-level muting for individual channels within loaded SMF files.

The program includes a visual representation of piano rolls and event lists to help users inspect note data in real time as the sequence progresses. It supports multiple output ports and allows routing different channels to separate synth devices simultaneously. The interface is geared toward musicians, educators, and hobbyists who need a straightforward utility for playing and inspecting MIDI files without heavy digital audio workstation overhead.
