Product Info

All knobs and no menus, an FM synth engine with hands-on control!

ALGO’s four through-zero oscillators can be configured in series, or parallel combinations, to create Complex FM or additive sound textures.

A unique Algorithm Display indicates the signal flow from one oscillator to another – easy-to-understand FM with pretty twinkly lights! Each oscillator has controls for Level and Frequency, allowing easy adjustment of FM timbres, no menu diving snorkels needed.

Modulation inputs for Frequency or Level for each oscillator – patch in a couple of Envelopes, and you have an instant FM synth voice.

Bored of Sine waves? A generous Wave Warp control bends things through Triangle to Pulse wave and back again. Wave Warp can be applied to Carrier, Modulator or both types of oscillators. For the more discerning mangler, Wave Folding is also available in three delicious flavours; Symmetric, Asymmetric and Soft Clip! A Global Detune spread control with CV input is great for creating Netflix apocalypse drones that descend into the abyss.

Lastly, an onboard Stereo Chorus can add a vivacious 1980’s shimmer to all your FM creations.

Oh, nearly forgot. It’s in Stereo!
