Skein is an FM synthesizer from Glitchmachines built around a per-cell FM matrix and a modulation panel system rather than classic digital FM architecture.

What Skein does
Skein is laid out around four operator modules, each with skew and noise controls, that feed an FM matrix where every cell sets its own modulation amount. Eight factory FM algorithms are supplied and can be overwritten. The developer describes the design as a deliberate departure from replicating classic digital FM synths, aiming instead at a new instrument for experimental sound design and electronic music production.
Modulation is handled through dedicated Mod Selectors. Clicking a selector opens a Mod Panel that lists the available sources, including four LFOs with 15 wave shapes and integrated oscilloscopes, and four sequencers of up to 32 steps each on a vertical grid. Poly Mode provides 12-voice polyphony and Monophonic Mode adds glide, and 160 presets sit across four banks.
Key features
- Operator modules and FM matrix. Four operator modules with white noise generators, a dual oscillator mode and a Skew control feed an FM matrix where each cell carries its own modulation.
- Modulation panel system. Mod Selectors open a popup Mod Panel that gives access to all modulation sources, so any key parameter can be targeted by several of them.
- Envelopes and filters. Four amplitude envelopes include Decay Mode, Release Mode Loop and Perc, and two multi-mode filters handle tonal shaping.
- Quad effects chain. Four multi-effects processors with local randomizers cover effects including distortion and bit reduction, seven effects in total.
- Voice modes. Poly Mode offers 12-voice polyphony and Monophonic Mode adds glide for lead lines.
- Presets and algorithms. Eight overwritable factory FM algorithms and 160 presets across four banks give a starting point for patches.
