I'll tell you, I played with the CM version of Fathom and bought the full version a few days ago.
This is a killer synth and an amazing value! It is better than synths costing 5X as much! If you haven't bought a copy of Fathom, what are you waiting for. It has one of the best designed UIs I have ever seen.
The only issue I have with it is CPU usage but that can be managed and the dev is working on optimizing the code.
Investing in the Fathom platform is a no brainer. Just do it.
