Tracker music is one of the great generally unknown "third way" [1] artifacts that arose from the Amiga and the demoscene. There are dozens and dozens of different formats, and even within 4-channel .mod files there are quite a few variants. What they share in common is not only a kind of technological approach to music formats, but an ethos to certain styles and kinds of music that seems to pervade across different generations of technology and artists. As a fully crystalized concept, it's around 35 years old! But it draws heavily on previous work in electronic music going all the way back to avant-garde experiments with reel-to-reel music crafting. As such it exists firmly as part of a grand, but often forgotten, part of electronic music making.<p>Largely speaking the tools to create the music are the tools used to listen to it and an implicit ethos of "openness" exists. You can literally see the notes being played, listen to the samples one by one, and even edit the song files as you wish. There are fewer better forms of immediate performance from composition, and musical pedagogy, in one compact technological concept.<p>Because it ties composition and performance into the same conceptual space (what you write is literally what it performed), and trackers are generally loaded with different ways of manipulating the samples and instruments, there can be a rich expressiveness encoded into the music that far outstrips what a composer might encode using a traditional note-and-bar midi composition program. And the "how" the composer encoded that expressiveness, how they used or abused the sample data, how they selected strategies around limitations of the format or software, is <i>all</i> present to see and learn from.<p>It also ties the specific sounds in with the note data, leaving very little room for interpretation. A tracker file should sound basically the same no matter what it's played on. Tracker modules are generally very small, a megabyte is usually considered large.<p>There are also some absolutely world class composers and songs in the pantheon -- across a wide variety of musical genres. And nearly all that music was composed and released into the world for free. And because there's never been a real commercial market for the music, the composers were very free to pursue their own musical interests. Genres range from dance music to highly experimental stuff -- sometimes by the same artist!<p>I think I once tried to get a rough assessment of the number of songs produced in the small community of tracker composers and it was well north of half-a-million songs...a literal life-time of music listening at absolutely no cost.<p>Here's a quick couple youtube playlists since it looks like HN crashed the archive<p><a href="https://www.youtube.com/watch?v=AVWFWvQBnZs&list=UUQ3Y8vCyrohM_xhIFFGkmWw&index=1" rel="nofollow">https://www.youtube.com/watch?v=AVWFWvQBnZs&list=UUQ3Y8vCyro...</a><p><a href="https://www.youtube.com/playlist?list=PLuprJ3W2ahOXgaIkH_Pf4De4JSFz6wo9l" rel="nofollow">https://www.youtube.com/playlist?list=PLuprJ3W2ahOXgaIkH_Pf4...</a><p>And the famous Nectarine demoscene streaming radio <a href="https://www.scenestream.net/demovibes/streams/" rel="nofollow">https://www.scenestream.net/demovibes/streams/</a><p>1 - By third way I mean not really commercial, not open-source, just a sort of unstated public domain.
