filtrr

filtrr is not just a filter! filtrr is a nonlinear ladder filter that is capable of producing a large variety of sounds. It can be modulated at audio rate, either with internal modulators or by using an external CV signal. It's capable of self-oscillation. It can be a lowpass, highpass, bandpass, and anything in between.

Features:

• Smoothly Morphable. filtrr is a filter with an ability to smoothly blend between lowpass, highpass, bandpass, peak and other shapes. The filter shape is also controllable with modulation.
• Unique Nonlinearities. Choose one of 6 unique distortion algorithms, ranging from subtle warmth and even-odd saturation to extreme squashing and nasty metallic folding.
• Built-in Modulation. filtrr has a built-in modulation system that is capable of modulating the filter cutoff, resonance, drive, gain and filter shape at audio rate, yielding cool and unique FM-like effects.
• Antialiased. filtrr uses a fast zero-latency oversampling algorithm to reduce aliasing. You have full control over the tradeoff between CPU usage and sound quality.
• CPU Friendly. filtrr uses extremely optimized algorithms, making it extremely light on the CPU. Includes intelligent bypass and auto update rate adjustment.
• Minimal UI. Simple to use and intuitive UI, optimized for fast workflow. Minimalistic design. Dark and light modes. Freely resizable.
