REVISED REVIEW: Not the Worst piece of software around!

UPDATED REVIEW 2-25-15: Received the new version 7.6 of the software from the Mixmeister people. They worked out all the bugs with Yosemite and it works perfect. I would recommend purchasing this. BUT PURCHASE IT FROM THEIR SITE, NOT THE APP STORE HERE. Thanks Mixmeister for being so great and giving me the upgrade from the previous versions.

Updated review after a month of trying to use this software. This is the biggest piece of crap software out there. I had the pro version of this software on my PC and purchased the express for my mac and boy is there a massive difference. Dont waste your money on this software. It is total crap in the Express version on the Mac. Jumpy playback, volume levels wont come in automatically with the tracks, will not scan music library automatically with crashing. Mixmeister support is horrible.

I recently purchased this for my MacBook Pro Retina and it will not run on Yosemite. I brought in my entire library, spent 4 days letting it scan and record the BPMs for each track and now I cannot use it at all due to the entire library of tracks disappears after it opens up. I have reached out to ME but have yet to receive any support to fix the problem. Dont buy this software until they work out the bugs for running on a Mac. The PC version runs beautifully though. I used to have MM Studio and freaking loved it. My advice, look at other options similar to this type of software.
