Virtual ANS is one of the deepest synthesizers to come to iOS in my opinion. This synth can create atmospheric sounds worthy of a sci-fi/horror major box office movie or action video game release. It is that good.
Visiting the website to view the video tutorials is a must as this synth is very complex to the uninitiated. Once understood you will be amazed at the broad soundscape available. For example, you can manipulate recorded audio like a painter, transform pictures into sound or reverse selected portions or the entire soundscape. The sonic manipulation power is immense similar to the original! Kudos to the developer for bringing a college university quality modular synth system to the IPhone!
