Timeline Structure

: An active C-based utility that focuses on the easy conversion of MIDI performance data into the MOD format, often used by developers targeting modern retro-engines like GB Studio .

While "conversion" sounds simple, the two formats handle music very differently. MIDI contains only note data, while MOD files contain both notes and the actual audio samples (instruments) .

Demystifying midi2mod: The Complete Guide to Converting MIDI to Tracker Modules

conv = MidiToModConverter() conv.load_midi('input.mid') conv.set_mod_channels(8) conv.quantize_resolution(6) # rows per beat conv.map_drums_to_channel(4) conv.add_fallback_samples() # simple square/pulse conv.write_mod('output.mod')

MIDI uses a high-resolution ticks-per-quarter-note system to capture precise human timing. Trackers use a rigid grid based on Lines (rows), Beats, and Ticks (speed). During conversion, the software must "snap" or quantize the MIDI notes to the nearest tracker row. 3. Instrument Mapping
