Ladder Filter

The Ladder Filter simulates low pass filters found in classic hardware synths.

Cutoff knob

The filter cutoff frequency.

Resonance knob

The filter resonance setting. High values will make the filter resonate at the cutoff frequency.

Topology

Selects between transistor ladder and diode ladder topology. The diode ladder have a slightly more gentle rolloff after the cutoff frequency. The two topologies also behave differently when saturation is enabled.

Saturate

Simulates saturation of electronic components in the filter.

Drive knob

Simulates overdrive of the components. Only available in "Saturate" mode.

Bias knob

Simulates bias voltage over the components. Only available in "Saturate" mode.

Settings panel

Whenever you have your mouse cursor over a snapin there is a small arrow at the top right corner (not visible in screenshot). It opens a settings panel where you handle presets.

It also has a "randomize" button that can be useful. I guess...

Enabled checkbox

The small checkbox to the left of the plugin name is a checkbox that bypasses the effect when disabled.

Resize handle

The bottom right corner of all Kilohearts plugins is a resize handle for scaling the UI to any size. This allows you to get a good view of the controls whatever the screen resolution, and also comes in handy if you need big controls, e.g. when using Ladder Filter as a real-time effect on a touchscreen monitor during a live set. (This is not available when the snapin is used inside a snapin host.)
