I managed to download the free trial version before they closed it off (I think it was the first day or two after launch).
Like many reviewers, I was underwhelmed and it definately feels like a work in progress. It’s so basic I’m surprised they’re actually selling it for $58 straight out of the gates. To be fair this is cheaper than the likes of Traktor Pro 2 but not far off the cost of Cross DJ which is far more developed and feature rich.
In it’s current state I couldn’t recommend it for serious DJing. It’s just too basic and lacks a lot of the features that you’d expect.
Mixed in Key on the other hand is a useful tool if you’re seriously thinking about harmonic mixing. Running tracks through MIK has become a standard part of my workflow and I even quite like the ‘energy’ rating even though I sometimes disagree with it.
The interesting thing now is that if you were seriously considering MIK you may as well just get Flow (they’re the same price), as its ‘Preparation’ section performs much the same functions as MIK (someone please correct me if I’m wrong) and you get the DJ software as well which will (hopefully) improve over time.
