s3xmodit is format primarily used for '[[OHB]s which allows for the submission of any of these tracker modules: - .s3m - .xm - .mod - .it Thus, "s3xmodit"! As one would have already guessed, this format is all about sample-based music and, sometimes, heavy manipulation of these samples. '[#[Software] .s3m, .xm, and .it were originally made in DOS trackers. s3m was made in Scream Tracker 3, .xm was made in Fast Tracker II, and .it was made in Impulse Tracker.

However, there are many alternatives to these programs that run on modern operating systems.

'[#[In Majors] In a major compo with a s3xmodit category, you are normally allowed to just submit any s3xmodit file with no restrictions (except under 10 mb) that you desire. See '[l[http://battleofthebits.com/arena/Battle/1035/Spring+Tracks/[Spring Tracks] and '[l[http://battleofthebits.com/arena/Battle/1403/Spring+Tracks+II/[Spring Tracks II] for more. For even more, look at any of the recent Winter Chip compos. '[#[In OHCs] A sample pack is provided and normally you are only allowed to use these samples, you may not add any samples to the sample pack (unless explicitly stated that you may add samples). More rare is the bitpack without the samples but with a simple text file with rules, or a .zip bitpack which contains both rules and samples. '[#[Size-based Formats] For large battles, module categories are usually grouped by size (8k, 32k, ect...) but will still accept any of the above mentioned modules. For size based formats, categories less than 64k will grant Chipist points.
