Dual analog VCOs and modular flexibility

Seashell’s sound engine is anchored by two fully analog, sawtooth-core voltage-controlled oscillators. These VCOs deliver a range of classic and experimental tones, offering internal waveform routing to the filter and wavefolder inputs. The analog wavefolder adds rich harmonic complexity, allowing musicians to sculpt anything from subtle overtones to aggressive, textured timbres. A resonant voltage-controlled low-pass filter rounds out the core synthesis capabilities, providing smooth cutoff sweeps and resonance for everything from warm bass to cutting leads. Parallel modular level outputs allow users to integrate Seashell into larger modular systems, expanding its capabilities even further.

Creative modulation and internal cross modulation

One of Seashell’s standout features is its internal cross-FM modulation bus, which provides deep and dynamic modulation possibilities between its oscillators. In addition, CV inputs allow users to bring in external modulation sources or self-patch for even more creative control. Whether building simple tones or complex, evolving textures, Seashell offers a rich environment for exploration without overwhelming patch complexity. Built-in macro controls mapped through the modulation matrix offer hands-on performance-ready tweaks that make sound-shaping immediate and intuitive.

Software control for deep customisation

Seashell’s dedicated software interface dramatically expands its functionality. Via VST3 integration, users can access high-resolution (14-bit) control over analog parameters, set up intricate modulation routing with a 4x4 matrix mixer, and recall complete sound designs instantly. A customizable scale transposition engine offers new harmonic possibilities, while internal LFOs and a versatile envelope generator provide deep modulation tools that are easily assigned through MIDI learn functionality. With USB-C audio and MIDI connectivity, seamless DAW integration becomes effortless, making Seashell a valuable tool for hybrid studio setups and live performances.

Built-in stereo DSP effects for added dimension

In addition to its analog signal path, Seashell includes onboard DSP effects designed to complement its sound engine. A stereo diffusion effect adds width and depth, perfect for crafting atmospheric pads or enhancing percussive elements. The effects are easily accessible and can be shaped in real-time, offering another layer of creative potential directly from the hardware interface.

Performance-ready design and connectivity

Seashell comes ready for both stage and studio. A stereo line and headphone output driver provides professional-level output without the need for additional gear. MIDI input via TRS connection and a user-definable external CV input and output allow for broad compatibility with a range of devices, from modular systems to controllers and sequencers. Every hardware control is designed for immediate interaction, providing tactile feedback and an intuitive layout that encourages performance and experimentation.
