A few years ago an official version of the Ultimate Beats and Breaks collection was made available digitally in WAV/AIFF format. Previously, someone had digitally encoded and or ripped the original vinyl/CD collection and you either had to get a copy from someone's hard drive or you could find torrents or shared links of the individual collections.
Well now you can have the UBB collection as REX2 and Pro Tools sessions. What's the point you ask? Check the video below and see how you can solo and mute individual sections of these beats. It will retails for about $69.00 USD. Pre-order at turntablelab.com
Here's a video of Lord Finesse using the collection in Serato Scratch Live.
