Filterstation2 is a powerful dual filter plugin developed by Audio Damage Inc. for iPhone. It is an impressive take on the classic serial/parallel/stereo dual filter topology, popularized by the Sherman Filterbank and its various clones. With twelve different filter algorithms, including an MS20 emulation and classic models like the 914 bandpass and Filterpod lowpass, Filterstation2 offers a versatile range of sound shaping possibilities.

One of the standout features of Filterstation2 is its envelope follower with stereo sidechain input, allowing for dynamic control of filter frequency. This feature adds a level of expressiveness and movement to your audio. Additionally, Filterstation2 includes a full FSU (Fuck Shit Up) section, perfect for those looking to add some extra signal hacking to their sound.

The plugin offers three operating modes: serial, parallel, and true stereo. This flexibility allows for creative routing and processing options. The LFO, with twelve different patterns and internal or tempo sync modes, further enhances the possibilities for modulation and movement.

Filterstation2 features an easy-to-use interface, making it quick and intuitive to program. The resizable GUI is vector-based, allowing users to customize the layout to suit their workflow. The plugin also includes a cross-platform XML-based preset manager, making it easy to share presets with friends and across different platforms.

Whether you're a producer, musician, or sound designer, Filterstation2 is a valuable addition to your toolkit. Its powerful filter algorithms, dynamic control options, and intuitive interface make it a standout plugin for iPhone users.
