I agree with Mutrix's opinion on the importance of live mixing during a Mixify set because listening to a prerecorded set would not be nearly as enticing for the fans and wouldn't allow the DJ their change set tracklist based on the instant feedback.
So far I've enjoyed listening to the sets completed by Mutrix, R3HAB, and Tritonal as they stood out above the rest (so far) in giving the online crowd that extra bit of interaction with the live tracklisting, frequent chatting and MC'ing, and live mixing that showed off the power of the Mixify platform.
The only way to see if you like the Mixify experience is to check it out yourself by visiting their main site. The RISE festival is in full swing with the likes of Stafford Brothers, Ken Loi, and Walden playing tonight while Feenixpawl, Arty, Popeska, Terravita, Deniz Koyu, Carnage, 3LAU, Bass Jackers, and Knife party are the headliners for tomorrow.
