Rekordbox, Denon DJ, DJ ethics, credits and digging.

Someone who has DJed for years usually has two libraries: the one prepared at home and the one that actually exists on the hard drive. The difference is discipline rather than quantity: who analysed, tagged and placed cue points, and what happens when the venue’s equipment differs from yours. A less visible layer sits alongside this: the ethical and legal framework supporting the craft.

This guide brings together pieces often omitted from technical tutorials. On one side are two common preparation ecosystems, rekordbox and Denon DJ. On the other are three questions of coexistence and authorship that arise sooner or later: DJ ethics, musical credits and digging with respect for sources.

Rekordbox: prepare at home, perform at the venue

Rekordbox is the database supporting much of the digital booth. Importing a file analyses tempo, beatgrid and key, then stores your markings: cue points, loops, tags, artwork and notes. The information is written in a format venue players read directly, so your home preparation appears identically in front of the decks.

Work order matters more than functions. First ingest with coherent naming, then analyse and correct grids, then cues and loops, and finally classify by energy and genre. Skipping that order creates partly functioning libraries: with misdetected tempo, the cue falls somewhere that is no longer bar one and prepared routines lose alignment when needed most.

Decide where the library lives and how often it is copied too. A master folder, backup copy and synchronisation routine before every departure prevent arriving to discover new files never reached the USB. The subject is completed in the DVS and library preparation guide.

Denon DJ: the alternative ecosystem

Denon DJ is the most established alternative for building a booth. Its catalogue covers standalone players, mixers and controllers, with its own preparation software and an onboard operating system that analyses and plays directly from the equipment. For buyers, its contribution is a genuine second option rather than a cheap imitation.

The useful comparison is continuity rather than specifications. If your library is prepared with one manufacturer’s software and travels on USB in its format, switching brands requires migrating data: cues, loops, key and folders. Many DJs maintain both worlds: prepare with their home tool and learn the workflow of venue equipment too, because there will be no time to read a manual when facing something different.

Look at support as well. A brand updating software and firmware regularly saves surprises at venues using different versions; an unmaintained platform stops being an option when the venue updates first. That, rather than a one-off price, determines an investment’s useful life.

DJ ethics: rules absent from the rider

DJ ethics is not written in a technical manual, but affects reputation. In brief, respect other people’s work: do not intrude on another person’s slot, play beyond the closing DJ’s finish, take colleagues’ libraries or files without permission, or use third-party material for recordings you will publish. None is complicated; applying them under time pressure and alcohol is difficult.

It also means respecting the venue and audience: honour agreed timings, maintain the night’s required energy arc rather than your ideal four-in-the-morning set, and avoid turning the space into a showcase for downloads. Opening, supporting and closing DJs have different roles of equal value; ignoring that hierarchy to shine is the craft’s most predictable mistake.

A third area is honesty about material. If you play someone else’s edit, use separation tools on another person’s work or record a session with material you cannot justify, know where you stand. Rights are described in copyright, master rights and publishing, where that conversation begins.

Musical credits: who appears and why

Musical credits separate two often-confused things: the work and the recording. The work is the composition, with its authors and ownership percentages; the recording is the particular performance you hear, with performer, producer and label. Each recording has its own identification code and each work circulates with authorship registrations; confusing the two causes most disputes.

That separation has practical consequences. When a song is published, someone must appear as author, someone as phonographic producer and someone as performer, with percentages agreed beforehand. Last-minute changes and percentages remembered from conversation are the quickest path to conflict between partners; professional practice therefore signs splits at the outset, even before the work is finished.

For someone only DJing, the question is simpler but remains: public performance generates payment categories managed through collecting societies and identification bodies. This is not legal advice, and each country has its own channels; it signals that venue music has a chain of names behind it that should be traceable. ISRC describes the recording identification standard, and CISAC’s network of authors’ societies maps representation by territory.

Digging and respect for sources

Digging means searching for music with judgement: exploring catalogues, stores, labels and archives to find material hardly anyone plays. It is the quiet work separating an individual repertoire from a new-releases folder. Physical and digital versions share one rule: the source matters as much as the track.

Respecting sources means justifying where every file came from. Buy where it is sold, record origins in tags, use pools and platforms with clear licences, and avoid downloads without provenance. The opposite has three costs: questionable quality, broken metadata and legal risk. The first is heard in the booth, the second wastes time weekly and the third appears when a recording starts circulating.

Reputation has a cost too. In a small scene, an edit’s origins are discussed; playing material circulating without permission places you on a particular side. Legitimate routes are mapped in legitimate sources and buying music, covering pools, stores and promotional platforms, where the search should be resolved rather than improvised.

One criterion for all five pieces

All five pieces answer one question: can you explain where the sound comes from? If yes, your library is traceable, material has clear authorship, the line-up works respectfully and your search distinguishes you. If not, buying more equipment does not fix it.

The learning order therefore moves from preparation to responsibility. First learn analysis and organisation, then move between ecosystems and, in parallel, understand how music is paid for, named and respected. It is less attractive than a booth trick and supports everything else.

This completes the discipline’s historical and cultural path: from origins to spaces, technique to digital, and tools to coexistence.
