Ferry Island Modular Four Seas

Four Seas is a four-dimensional wavetable oscillator that transforms sound exploration into a tactile, intuitive experience. Navigate through sonic space using X, Y, and Z controls to explore wavetables as a three-dimensional cube, while the fourth dimension emerges through four related outputs with intelligent spread controls.

From gentle detuning to complex microtonal relationships, the frequency spread control offers multiple modes including harmonic ratios, prime numbers, and golden ratio proportions; everything from lush chords to experimental frequency relationships is at your fingertips. The four outputs cascade across the wavetable space, creating rich, evolving textures like light dispersing through a sonic prism.

The powerful modulation section features thru-zero phase modulation, phase distortion waveshaping, and fixed-point scalar underflow ("FSU") modes for complex sound design. Dual sync inputs with selectable modes, CV control over wavetable banks, and SD card loading for custom wavetables complete the package. Each oscillator pair can switch to LFO rates for modulation duties, and I2C interoperability allows integration with Teletype, Crow, ER-301, and other modules (specific support coming soon). No menus, no presets - just immediate, musical control over a vast sonic landscape.
