Nettle is a software instrument that delves into the distinctive realm of scanned synthesis, offering sound creation that continuously evolves over time. The instrument generates waveforms by tracing the positions of masses in constant motion, simulating the dynamics of physical interactions. When a key is pressed on a MIDI controller, it mimics the impact of a hammer striking interconnected masses, setting them in motion and producing unique tonal textures that change organically.

Users can shape the sounds by adjusting the properties of the masses, the springs connecting them, and the excitation mechanism, resulting in dynamic and expressive sonic possibilities. Nettle supports 32-voice polyphony and provides extensive modulation options, including four LFOs, ADSRs, and MIDI controller sources, enabling detailed control over sound movement and character. The instrument also includes low-pass and high-pass filters alongside reverb for enhanced sound processing.

With a user-friendly interface, Nettle offers fully automatable controls and a collection of built-in presets that can be saved and customized to suit individual preferences. Its randomize feature encourages experimentation, making it a powerful tool for creating evolving textures and dynamic soundscapes. Nettle is accessible for download and invites users to engage with its innovative approach to synthesis.
