“I use a lot of GOLDVOLTRON’s production in my live sets. The Speed Booster is the perfect way to train and get faster! I wish we had this instead of moving the pitch fader when we first started out!” - DJ QBert

"If you need a quick beat to kut to whether it be fast or slow, look no further - download the Thud Rumble/Warflex app now!" - DJ Shortkut

“I always wanted to help DJs train continuously with no breaks, furthering their skills beyond what they thought they are capable of doing.” - Yogafrog

Warflex Gold is the ultimate training tool for DJ's, just plug your iOS device into your mixer and turn up the volume! Imagine unlimited uninterrupted beats on Thud Rumble’s new music label on the App Store. Their chosen drum machine king, GOLDVOLTRON, unleashes 25 searing beats for the ultimate skratch practice -- for just 99 cents! Train non-stop until your skratching skills are honed to perfection!

Not happy

I bought this and all related apps. When I open it and push on an icon to play the beats there is no sound on all four apps I bought. Refund please

Developer Response ,

I believe we may have spoken a year ago via email, but for anyone else having problems as well: Please make sure your mute switch on your iOS device is turned off; if your ringer is on mute, the apps won't output sound. This changed around iOS 7, we've tested with each major version of iOS since; sound is working in all four apps. If you're still having issues, please drop me a line at rich @ , thanks!

Sick beats... For sick Djs... From sick Djs... I think I'm gonna be sick... Great app for birthday parties, weddings, bar mitzvah, sweet sixteen, debuts, quiceanera, baptisms, funerals, solitary confinement with some 1200's, massages, meetings, dating, impressing hoes with your skratchin', the office, the university, the classroom, the plane, the plane, the Lab, the studio, the 500sq foot apartment with nothing but vinyl and decks taking up 300sq feet of space, the basement, the addict, the garage, the bedroom, the shower (microphone not included), the closet (R Kelly not included), the show, the session, Q & A's, the rehearsal, the battle, the endless practice, the hours, the dedication, the A.D.D, the O.C.D, (not great for STD's... Sry...Nobody can help you there), and last of all... Great for the DJ, Breaker, Pop Locker, Tap Dancer, and MC.... Turntablism of the 21st century!!!!
