Skein is an FM synthesizer designed for experimental sound design and electronic music production. It features a unique four-operator system with skew controls and integrated noise, allowing users to create complex tones beyond traditional FM synthesis. The instrument includes a flexible modulation matrix with per-cell modulation and user-definable algorithm presets, providing deep control over sound shaping. Its interface offers access to multiple modulation sources such as four LFOs with various wave shapes, modulation sequencers with up to 32 steps, and multi-mode envelopes, enabling intricate and evolving soundscapes.

This synthesizer takes an innovative approach by focusing on creative experimentation rather than emulating classic digital FM synths. It comes equipped with a versatile effects chain featuring distortion, bit crusher, chorus, phaser, delay, reverb, and buffer effects, all of which can be rearranged to tailor the sound processing flow. The dual multi-mode filters provide additional tone sculpting options with lowpass, highpass, bandpass, and notch modes. Skein’s modulation panel system includes dedicated selectors that open detailed controls for each modulation source, making it easy to build complex modulation routings and dynamic textures.

Skein’s operator modules include white noise generators and dual oscillator modes with a waveform skew control that adds harmonic richness reminiscent of sawtooth waves. Envelopes offer multiple modes including decay, release, loop, and a percussive mode optimized for sharp transient sounds. The sequencers offer precise step control and utility functions for rapid programming, while the effects chain’s local randomizers encourage creative exploration. With polyphonic and monophonic modes, along with glide features, Skein suits a wide range of musical styles and production needs, making it a powerful tool for crafting unique and expressive sounds.
