 More DJ effects and OSC banks forthcoming—watch for updates! Customer Review A superb collection of streaming stations! The only thing I would like to see added is some ambient/dark-ambient/soundscape channels, and the ability to use the app in landscape mode. Even without these features, it's a great app! If you are a fan of DubSiren DX this will not disappoint. by zounds23 Electro sounds to modulate =) Nice features with the scope of changing the parameters of all the osc as u play =) Great radio with tons of stations, buy for the waves, Thanks again for another sure-fire mixer #one #fantasykrew by MultiplayerAgency Amazing!

Hands down for these guys are changing how I listen to music! by Ian SF - Version 1.0 - Nov 28, 2013 Awesome app from the makers of Dub Siren! Love this app! Have been waiting for them to make an app utilizing electronic music. The interface is easy and has some great features! A must buy for any club DJ to use in their set. Although, I'm enjoying it from the pleasure of my home. A+ Sawa Digital! by meljunew
