Sidraw

ExperimentalAnalogParaphonic

Imagine coaxing glitchy, screaming tones from seven triangle wave oscillators chained in FM feedback, all sparked by your fingertips on touch-sensitive sandrods—a direct evolution of Ciat-Lonbarde's chaotic Sidrazzi circuit.

Sidraw packs seven paraphonic voices into a compact analog frame, with each oscillator FM-modulated by the previous one and depths unified under a single master knob. Touch points serve as glitch inputs for direct body manipulation, sparking unpredictable pops and bursts, while dedicated glitch inputs and a direct VCA port let you inject external signals into the frenzy. A master pitch knob anchors the madness, and the single square wave output delivers raw, unfiltered audio alongside CV/Gate ports for modular integration. Its black-and-gold handmade build feels intimate, like a secret instrument built for tactile explorers.

Owners cherish its wild, organic chaos—perfect for texture-hunters who love the Sidrazzi's spirit but crave Meng Qi's refined touch interface. A few note the steep learning curve for taming its glitches into melodies, but that's part of the addictive draw. If you're chasing experimental sounds beyond knobs and keys, this discontinued gem still haunts secondhand scenes.
