The Koszalin is a seriously cool module if you're into crafting unusual, shifting textures and exploring FM territory. It’s not a straightforward chorus or flanger; it’s a sonic playground for experimental sound design and creating evolving drones and pads. Perfect for sound designers, ambient musicians, or anyone wanting to add a layer of unpredictable movement to their modular system.

Frequently Asked Questions

While both introduce frequency relationships, Koszalin's Through-Zero FM offers more nuanced, controlled harmonic complexity with adjustable ranges and modulation options, avoiding the often harsher tones of a ring mod.
The feedback path is surprisingly controllable; the selectable modes and dedicated CV input allow for both subtle shimmering and intense, self-oscillating textures.
The stereo input has a clip LED, so it's designed to handle dynamic signals, but pushing it too hard will result in intentional distortion, which can be a desirable effect, but requires careful gain staging.
