OttoPhilter is a dynamic auto and touch wah filter plugin designed to enhance your sound with expressive modulation. It features two driven resonant filter sections that can be applied independently to the input signal and a generated sub-octave, allowing for rich tonal variation and depth. The filters can sweep smoothly, controlled through triggered envelopes, input signal tracking, or customizable low-frequency oscillators (LFOs).

This plugin includes a sub-octave generation feature, which adds a deep, resonant layer beneath your original signal. Both the main and sub-octave filters respond to touch sensitivity, offering nuanced control over your performance dynamics. A level meter is integrated to help you fine-tune the touch wah sensitivity, ensuring that OttoPhilter precisely matches your playing style and expressive needs.

With its combination of auto and touch wah capabilities, dual filter sections, and sub-octave processing, OttoPhilter provides a powerful tool for shaping your sound with movement and character. Its flexible modulation options make it suitable for a wide range of musical contexts, adding dynamic filter effects that respond naturally to your input and creative intent.
