I know this is not a news blog but I have had a chance to try this out and it is very professional and about the best non-scratching DJ app I have tried. Here's the rather extensive list of updates:
Universal app with native iPad and iPhone interfaces.
New interface design, new minimal look.
New workflow, new navigation. No more "which side is which" and "where am i".
No importing necessary: directly uses your iPod library, with playlist support. Mass analyzing of iPod library tracks, sort by BPM too. USB or WiFi upload is still available.
Serato and Traktor metadata support (BPM and cue points).
Much-much lower latency, reduced CPU usage. Feels faster.
Double-deck output mode for hardware mixer.
4 gapless cue points, play like a sampler.
Reverse play (tap before or after the pitch fader head).
Auto beatgrid and waveform display.
Automatic Vinyl Vision creation in background.
Better sounding flanger and echo.
Navigate between the screens using a gesture (iPad only, slide your finger from outside of the screen towards the center).
Swap play/cue button position.
Sharp echo/reverb release on/off.
iPad only: master output fader, master VU meter before or after.
Network BPM sync: if there is only one deck loaded, the app broadcasts and receives the current BPM value over the local WiFi network or Bluetooth, so you can sync between different devices. Very useful in Classic Club mode, or when you switch DJs in the booth.
So there you go. Definitely worth a try!
