It’s beta 2 of Deckadance, the underdog Mac/Windows DJ app that’s surprisingly full of functionality. And while this isn’t the first DJ software to do sampling and effects, those features are now tied to some powerful automation and envelope features we haven’t seen in a conventional multi-deck DJ tool. They also accompany a KAOSS-style, X/Y multi-effects VST plug-in that users of other hosts might want separately.

Decks – 2 or 4 decks.
Smartknobs – Link a knob to multiple FX & Mixer interface targets. User-programmable envelopes.
GrossBeat – 8 user defined FX per deck with integrated editor. Program glitch, stutter & scratch FX.
Isolator Effects – Up to 3 insert effects per track (from 10) applied independently to High/Mid or Low band.
Sampler – 1/32 to 16 step beat-matched easy sampling. One shot, trigger, retrigger and loop modes.
Smart Panels – User configurable Loop, Cue, Grid, DVS, Key, Smart Knob and Tempo panels.
VST host & client – Hosts VST plugins. Includes Effector VST plugin.
Library – iTunes library support. Play lists and automated mixing options.
