What it is

SetPrep is a desktop app that plans DJ sets from an existing music library. Choose a mixing style and it returns an ordered set, giving each track an energy-arc role, a transition note, and an explanation of its selection. It reads libraries from Rekordbox, Serato, or Traktor, and can also work from a folder of audio files. Ten built-in mixing-style templates draw on analysis of real artist sets. SetPrep can write colour codes, transition notes, and star ratings back to supported DJ libraries. Other library tools include de-duplication, locating missing files, filename repair, and finding forgotten tracks. The beta is available on Mac with Apple Silicon or Intel and Windows with x64 or ARM64, but downloads are invite-gated. The free plan costs nothing and allows three generated mixes per calendar month. Pro Monthly costs £5.99 a month; Pro Annual costs £59.99 a year. Hot cues, loops, memory cues, and structural cues are described as coming soon.
