Learn how to build a simple low‑pass gate (LPG) in Pure Data Vanilla, combining filtering and an envelope for that "West-Coast", organic, percussive sound.
In this no-talking, patch-from-scratch video, I create a basic LPG patch, showing how to combine a low‑pass filter with an envelope to emulate the behavior of classic analog LPGs used in modular synthesizers like the Buchla.
Low‑pass filters, unlike VCAs commonly used in "East-Coast" synthesis, change both the timbre and amplitude of a signal at the same time. Emulating this idea in our digital synths can be a cool way to create natural‑sounding plucks and percussive tones.
0:00 Making an AD envelope
0:29 Applying the envelope to a LPF
1:06 Clocking with a Metro
1:34 Exploring different fake vactrol behaviors
