FAQ
What is Multimode Ladder Filter based on?
Multimode Ladder Filter is modeled after the 4-pole (24 dB/oct) ladder filter topology originally designed by Robert Moog in 1965. It aims to replicate the warm analog sound of that classic design.
What filter modes does Multimode Ladder Filter offer?
Multimode Ladder Filter provides five distinct filter modes: lowpass, highpass, bandpass, notch, and resonant. This allows for a wide range of sound shaping possibilities, from classic subtractive sweeps to sharp leads.
Can Multimode Ladder Filter create distortion?
Yes, the app features tanh saturation at the input and feedback stages, producing warm analog-style distortion. This distortion scales with the drive and resonance settings, allowing for dynamic tonal shaping.
What happens when resonance is high in Multimode Ladder Filter?
At high values, the resonance setting drives the filter into self-oscillation. This generates a sine tone at the cutoff frequency, adding a unique sonic character to the processed audio.
Does Multimode Ladder Filter have ads?
No, Multimode Ladder Filter does not contain advertisements. As a paid application, it offers an uninterrupted user experience.
