App Store Description:

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.

It's 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.
