Modulation Parameters

These modulation parameters control an old-school dubstep-style auto-wah that is the core of SousaFX.

mod parms

Several mod params can be set via the bindings.

  • Subdivisions [no user interface]

  • LFO Ceiling Envelope Curve [this binding’s movement is visible in the ceiling & floor function]

  • LFO Duty Cycle [this binding is offset by the High Freq/Amp Mod duty cycle parameter]

  • LFO Swing Amount [Auxiliary LFO depth]

  • LFO Sync-Free Crossfade [no user interface]

  • LFO Free Speed [no user interface]

  • LPF Resonance Amount [LPF Resonance Range & Amount]

  • Show LFO Visualizer

    Displays a visualization of the four LFOs.

  • env sens

    Adjust the envelope sensitivity, which corresponds to the x-axis input of the ceiling and floor functions.

  • ceiling and floor

    Determines the depth of the lowpass filter frequency modulation, AKA the frequency range of the dubstep wobble. Bindable via “LFO Ceiling Envelope Curve (bi)”. The “env smooth” dials determine how quickly the range can change. The “y pos”, “x pos”, and “ceil max” dials set the shape of the function.

Select Lowpass Filter Type

The lowpass filter selector switches between a collection of gen~ filters, and optionally, two paid plugins: Moog MF101S, and Cytomic The Drop. This selection is saved independently of the main presets, and shouldn’t be switched live.

lowpass filter selection

The gen~ filter selection, however, is saved with the main presets, and can be switched live.
