Iam EXTREMELY happy to report that I downloaded a demo of Mix Emergency 2.1.0 tonight and it works flawless with serato 2.4.2.!! I have a rane 62 mixer with the latest firmware update and I use it via midi with a denon 3900. LOVE IT! LOVE IT! LOVE IT! Finally I can record my video mixes!!! The random transitions is also a plus. I can not say enough great things about all the additional effects and transitions that are included as well. After using video video sl for over 2yrs I had hoped the new serato video would include video recording, the ablity to have random transitions and also additional effects/transitions. I was let down to say the least. I do understand that the ''back end architecture'' was revamped on Serato video in order to allow further upgrades and improvements but it is too little too late. I am offically purchasing Mix Emergency as soon as the beta testing is done. For all you VJs out there who have been holding off on buying a Rane 62 because it wont work with Mix Emergency....GO BUY a RANE 62- it WORKS with Serato 2.4.2 !!! - VJ Chino
