Recue | Four Seas VCO: Breaking Waveforms with Audio Inputs

video upload by Ferry Island Modular and Recue

"Recue showcases an awesome hybrid workflow with Ableton, in which Four Seas is used both as a VCO and an audio processor. Make sure to watch until he hits to spot. 🤩

'On this patch Four Seas is hooked into Ableton Push, which is spitting out both CV and audio into it. I got excited about the idea of audio input modulating the oscillators, so Push is playing a simple bass line with the module and sending a beat into the audio inputs distorting and breaking the waveform apart in all the right places. All other modulation in the patch is done by hand, sweeping for the sweet spots. Audio is fed back to Ableton where there's bunch of effects after for live manipulation.'"

Hear the Fourth Dimension with Four Seas

"The Four Seas wavetable module is a powerful sound-sculpting tool designed for anyone looking for cutting-edge timbral control. This video dives deep into its evolving wavetables, spread modes, and performance-ready interface, showcasing with musical examples how the Four Seas can give you tons of expression.

Divergent Waves Sycamore playing Four Seas and Friends

video upload by Molten Music Technology

"A quick demo of my newly built Sycamore melody generator. It's running into the Four Seas wavetable thingy, which is being filtered via the Riot VCF, into the Trifecta effects. Meanwhile an Ona VCO is pumping the second channel through a Gemini Vintage filter. There's some modulation too!"
Divergent Waves - Sycamore Demo

"Sycamore is a looping, quantized, randomised sequencer with 45 scales to choose from, as well as a few tricks up its sleeve...

Sycamore is based on the (Cancelled) Mutable Instruments Seeds module, which itself was likely an exploration of Turing Machine like sequencing with a little more control."

"Sycamore is a random looping sequencer with quantization and a wide range of scales. The quantized loop can be shifted, mutated, tweaked and otherwise fiddled with in a number of interesting ways.

With CV over almost all the internal parameters, Sycamore allows for tight control over the loop, while maintaining performability with comfortably spaced knobs.

Some advanced features are accessible through a one-layer menu to allow for more deep tweaking of harmonies, delay, and scale quantization - however, Sycamore is perfectly usable without touching these at all!

Sycamore makes use of CircuitPython for its program code, allowing for easy modification and tweaking should you wish to do so. The module also features an i2c expansion port reserved for future use, or for you own hacking.

FOUR SEAS // A Multi-Voice Mega Wavetable Oscillator Powerhouse from Ferry Island Modular

video upload by DivKid

"Here we have Ferry Island Modular's first release 'Four Seas', which is designed, engineered and manufactured in Finland. It's a real power house of a sound source, suiting to quickly grabbing some waves to patch with or for deep sound design tweaking. Everything is knob/button per function with no menus, making complex behaviours, modulations and sounds simple to access. There's LOTS of examples in this video, see the timing index below for all that's covered ... yet I'm sure there's lots left to uncover with all the options this presents."

Superbooth25 wrapped up

video upload by Ferry Island Modular

"May 18, 2025
Last week was our first time at Superbooth as exhibitors introducing our first module Four Seas. In this video we wrap up our experience at Superbooth and feature sounds from Four Seas, created and generated by our booth visitors. Thank you to everyone who came by to check out Four Seas, it has been a genuine pleasure to see what you created with it."

Four Seas - sound teaser #1

"Here's a demo jam showing off a few things Four Seas can do. All sounds from Four Seas aside from the bass drum from Basimilus Iteritas Alia and the reverb/delay from Mimeophon. Hope you enjoy!

Patch notes:
0:00 - oppressive bass
0:20 - through-zero phase mod, courtesy of Dixie II+
0:45 - hi-hats/percussion using Wogglebug's audio out as a phase mod source
0:58 - swirling synths; two Four Seas outputs mixed into 3 Sisters, wave spread modulated via joystick
1:36 - awesome glitchy "open hats" triggered via Wogglebug's Burst output"

"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 control.

From gentle detuning to complex microtonal relationships, the 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 wavetable space through intelligent spread algorithms, creating rich, evolving textures like light dispersing through a sonic prism.

The powerful modulation section features thru-zero phase modulation, phase distortion waveshaping, and bitwise XOR 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 compatibility enables integration with Teletype, Crow, ER-301, and other modules. No menus, no presets — just immediate, musical control over a vast sonic landscape."
