Physical Audio Tetrad v1.1.4-TCD

Tetrad is a hybrid instrument that blends physical modelling with granular synthesis to create evolving, experimental soundscapes. Designed in collaboration with composer Gadi Sassoon, it routes four oscillators through a Quad AM processor that acts like a pseudo-sequencer, then into a custom granulator and four physically modelled plate resonators. A full modulation matrix lets you deeply shape the signal flow across the quad bus architecture. This isn’t a preset-friendly rompler—it rewards hands-on experimentation, making it ideal for hobby producers into ambient, cinematic, or sound-design work. Whether you’re using FL Studio, Ableton, or Logic on Windows, Tetrad offers a distinctive alternative to standard subtractive synths. It suits those who want to move beyond conventional sounds and explore textured, resonant tones that respond organically to modulation. The compact 6.8 MB size keeps your system light while delivering a complex, interactive engine for crafting unique pads, drones, and rhythmic textures.
