Deejaysystem vs DJ.Studio

Deejaysystem is a Windows series of digital audio and video mixer applications for DJs and VJs working with live or automated sessions. Audio Mk2 provides two independent audio decks for live mixing and automated playback. Video VJ2 handles movies, music videos, karaoke, and audio files, and can play two videos in a DJ-style setup. Its video controls include a crossfader with six effects, multiple screens, and up to two live cameras at once. AutoPlay can choose tracks without repeats, mix the current track with the next, and adjust fade-in and fade-out volumes. Users can control the software with a keyboard, joystick, or MIDI-compatible controller and customize mappings. The free Mk-I plan is unrestricted and fully functional, but limited to one deck and one soundcard. Paid Audio Mk2 costs €59, paid once; Video VJ2 costs €149, paid once. Applicable taxes are not included. Their evaluation copies stop after 30 minutes and must be restarted to continue.

DJ.Studio is a timeline-based app for planning, editing, and exporting prepared audio or video mixes, rather than playing live sets. Its Harmonize feature orders playlists using tempo and harmonic matching based on the Camelot Wheel. Users can edit transitions and add effects, automations, and samples. Listed music sources and library connections include Mixed In Key, rekordbox, Serato, VirtualDJ, Engine DJ, TRAKTOR, iTunes, Beatport, Beatsource, YouTube, and computer libraries. Mixes can be exported as WAV or MP3 files, sent to Mixcloud, or exported as video for YouTube. The app is available for macOS, Windows, and the web. After downloading and signing in once, it can work offline, though online features such as Beatport search are unavailable. A seven-day trial requires no credit card and does not automatically become a paid subscription. The one-time license provides lifetime use for one user on up to two machines, with 12 months of updates and support. Video export and VST support are in Ultimate; stem separation is available in Pro + Stems and Ultimate.
