Numerical Audio has today released SF-1, a new performance-oriented stereo filter app with AUv3 support for iOS. It offers SEM & Ladder filter models, modulation options (dual LFO…) and an XY-pad with automation. With the latter, you can play the filter very expressive what is very nice.
SF-1 is a dual stereo filter effect with a special focus on expressiveness. Built around 2 multimode filters with multiple filter models that can be configured to run in series, parallel or one per channel, SF-1 is true filtering powerhouse. Its built-in XY-Pad can be automated over a maximum of 4 bars which makes sequencing complex filter sweeps as easy as it could possibly be.
With pad-lock, the XY-Pad will always return to a set location after lifting a finger allowing for a wide range of play styles. In addition, Pad-Engage/FX-Release only enables the effect while the XY-Pad is being touched and applies a tempo-synced delay effect when lifting the finger making it a great option for expressive live performances.
