Stack the before a big reverb and a delay. Set Sap maxed, Root at 3 o’clock, Canopy dimed. Here, the pedal ceases to be a distortion and becomes a texture generator . Palm muting produces a low, breathing rumble. High notes sing with harmonic feedback that isn’t harsh—it sounds like wind through a pine forest. You are not playing riffs; you are painting with resonance.
Every evening, Mira opened the file. Inside was a sparse, procedural forest—fourteen trees, to be exact, arranged in a gentle arc around a stream that never ran dry. The "CS15" stood for "Code Seed 15," her fifteenth attempt to grow a forest that felt alive . The "Trees 4" was her fourth revision of that seed.
From the moment you open the box, the asserts its identity.

This collection is favored by developers for its balance between high visual fidelity and performance, often used to create dense, realistic forests or landscape scenes.

Finally, "Grove" is the master volume, but with a twist. It is post-all filtering, meaning it doesn’t change the character of the previous controls. It delivers unity gain around 11 o’clock, offering up to +20dB of clean boost for driving your amplifier’s front end.

It is about resonance, air, and the natural compression of organic material.

Known for immaculate craftsmanship and circuits that behave more like living instruments than sterile electronics, their "CS" series has developed a cult following. With the , the builder has moved beyond simple gain staging and into the realm of organic harmonics, dynamic response, and what can only be described as textural landscaping .
