Octasynth

The Octasynth isn’t a synth emulator—it’s a true analog synthesizer in pedal form. Built around classic synthesis ICs, it transforms your guitar signal into three square-wave octaves, then shapes them through a resonant low-pass filter—the same fundamental formula behind most iconic analog synth tones: raw waveforms plus resonant filtering. Designed to be powerful without being overly complex, the Octasynth keeps controls intuitive so you can easily dial in and recall your favorite sounds. Its dynamic tracking responds not only to the notes you play, but how you play them. Pick attack directly influences the filter, delivering punchy hits, vocal-like sweeps, or deep resonant textures via the Depth and Resonance controls. The filter automatically closes when you stop playing, eliminating sputter and unwanted noise. The result is expressive, playable, and unmistakably analog synth tone—straight from your guitar.
