Filter

Removes highs, lows, or everything but a band around the cutoff

Open in the synth with a demo patch Open Modular

What it does

A filter cuts away part of the spectrum: low-pass keeps everything below the cutoff and makes the sound darker and softer, high-pass keeps everything above it and leaves only a whisper, and band-pass keeps a narrow slice around it. Cutoff is the frequency where that boundary sits; Q (resonance) emphasises the frequencies right next to it and starts to sing at high values. The Cutoff input lets something else move that boundary, an LFO for instance.

Try this

A saw from a Drone through a low-pass at 400–800 Hz: that is how a saw turns warm and syrupy.
Patch LFO → Cutoff and play with the cable amount: 0.2 is a gentle breath, 0.6 a clear “wah”.
Band-pass with Q around 8 on noise sounds like wind whistling through wires.
