Developer algoriddim has released djay 2, an upgrade to its DJ app for the iPhone
. Much of the interface has been overhauled, for instance making it easier to switch between different modules. Tilting a device into portrait orientation brings up a new single-deck mode, offering bigger controls while still letting people jump to the second deck.
Part of the interface revision includes a new music library with song queues, histories, and previews. Libraries can be analyzed to detect BPMs and waveforms, and sorted according to BPM, artists, titles, or times. The library window can be expanded to fullscreen and set to either a light or dark theme, the latter being intended for dark nightclubs.
New performance tools include a sampler, which is matched by a 12-button drumpad. DJs can use one of the app's bundled samples, or create their own from music playing on the decks. The drumpad can be customized with preset configurations and color-coding.
Along similar lines, the app now uses color-coded waveforms to help pinpoint the intros, choruses, and verses in tracks, as well as smaller elements like drums, vocals, and basslines. A Slice mode lets DJs turn beats in a waveform into temporary cues for remixes, while a Slip mode lets people scratch and still have the music snap back.
An especially important new feature is Perfect Sync. The option can quantize music on the fly, ensuring that tracks on the decks never drift out of sync from each other. This can be used either for perfect transitions or to create mashups of two tracks. A tool called Loop-FX, invoked by swiping across the XY pad, can create beatmatched loops with simultaneous filtering.
The iPhone app is currently on sale for 99 cents; the flagship iPad app costs $5. A week from now those prices are due to go up to $2 and $10, respectively. Both versions of djay 2 require iOS 6 or later.
