Easy to use, nice interface and excellent quality. The only downside is that you have to download the IK multimedia Custom Shop and it comes with all the plugins for the T-RackS on trial mode, so you end up with more than 20 plugins you will never use unless you buy them. But still, it is a good plugin nontheless.
What can I say? This synth is amazing. Even if you use it just as a substractive synth you can get high quality sounds. It is indeed a great year to be a broke music producer, there are many free vsts out there and Vital is one of the bests. It is my go to synth every time I start a new project.
When I get money again I will donate to Matt Tytel so he continues making his awesome job. That said, I encourage everyone that can spend a bit of money to buy the plus or even the pro version of this synth.
