Reply to MixMeister Fusion replacement for studio mixes?

Hi guys,

I've used MixMeister Fusion to mix a few ambient mixes. The UI is a piece of crap, but the functionality is pretty great. Alas, it no longer works on my Retina MBP and it does seem to be abandoned.

I'd like to find an app to replace it. It should have key detection, beat grids, and preferably an equalizer that works similary to the one in MixMeister, i.e. with lines that you "draw" on the tracks.

What are your suggestions?
