The graphical interaction provides a great tool to design an extremely precise and smooth frequency response by directly manipulating up to 36 Peaks Filters. The Spectral Grid compilers increase the complexity and coherence between the filters bandwidth space. You can create your pitch space by the way of four different criteria of construction by determining a pitches grid: Fibonacci, Harmonic, Geometric and Scalar.

Amazing Filter Machine

Like many of this dev’s apps, this is very creative and functionally deep with excellent sound quality. As well as being superb value for money, it has all the latest updates required for an iOS app to cooperate with other music apps. Fully recommended.

Absolute Must

Fabulous app for playing with samples and using in effects with audiobus ,IAA great midi features and wonderful filters,what's not to like !

Bright sounds, blinding interface

On the plus side, this app continues to evolve the sounds it can produce in interesting ways, and maintains that crucial AudioBus compatibility. But, please give us a way to tone down the new ultra bight interface. I almost need sunglasses to look at it.
