Audio examples

When you're looking for a bit of that vintage feel, Ladder filter will twist your basses into squelching retro-licks akin to those of the Moog or the 303. Crank the drive up an extra notch and it will even function as a warm distortion. Mmm, smooth.

Ladder Filter is one of the devices in the Kilohearts Toolbox bundle.

Product details

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

  • Cutoff - The filter cutoff frequency.
  • Resonance - 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 - Simulates overdrive of the components in saturate mode.
  • Bias - Simulates bias voltage over the components in saturate mode.

The Kilohearts Toolbox

Ladder Filter is one of the devices in the Kilohearts Toolbox bundle.

The Kilohearts Toolbox devices all do one thing each, and they do it well. The philosophy behind this is to give our customers access to the building blocks of sound design and from there you can combine them into really interesting effects. In fact, many more esoteric RE:s are basically a few of these effects combined.

If you own a few, or all the Kilohearts Toolbox devices be sure to check out Kilohearts Toolbox Refill, a big pack of diverse combinators exploring the possibilities of the toolbox.
