DJ on the Go. Sonorasaurus Rex 2.2 is finally here! Start mixing now with new features like Hot Cues, Deck Split mode and waveform scrubbing. Plan your next gig with Playlists! Mix songs directly from your iPod Library! Record your mixes on the iPad real-time! Review: "Rex can indeed hold it’s own as a viable dj app – and certainly worth the money."

Designed by and made for real deejays, Sonorasaurus Rex is a serious mobile DJ offering that meets the demands of professional and casual deejays alike.

Rex sports two independent decks, each with their own dedicated effects module, cue points, permanent and temporary pitch controls, level meter, parametric EQ and gain adjustment. Mix these however you like -- whether by Headphone Split using a Y adapter, Deck Split using your own external mixer, or if you're feeling adventurous, with the aid of Beat Blobs and touch-sensitive waveforms. From v2.1, you can now record your mixes on the iPad in high quality 44100Hz WAV format, and export them to your computer using iTunes File Sharing.

Because Sonorasaurus Rex contains everything you need, it lets you carry your turntables, mixer and music library all on one device, without either the cost and bulk of professional hardware equipment.

Is the radio not entertaining your guests? Create the perfect soundtrack at the your next house party!

Flying to a gig? Practice your mix in your headphones and figure out what songs work best together before you are even at the venue!

Want to make travel seem shorter? Entertain your friends with your favorite mix of songs on your road trips!

Two turntables not enough? Set up Sonorasaurus Rex on an additional channel and add an extra layer to your mix!

Equipment malfunction right at the worst possible time? Keep Sonorasaurus Rex around as a handy backup performance solution!

Regardless of your skill level as a deejay, pro or amateur, its great to have a deejay solution right in your palms. After all, Sonorasaurus Rex is a lot lighter than most equipment and costs hundreds of dollars less.
