Avalith Semi-Modular Drone Synthesizer

Imagine coaxing a colossal wall of sound from 100 raw transistor oscillators, each humming in the unstable negistor state—like electricity itself coming alive in unpredictable waves.

This semi-modular beast packs those oscillators into 10 banks of 10, with individual control wheels for frequency, starve knobs to voltage-hunger the transistors for glitchy ramps and dense textures, and per-bank CV inputs plus dedicated I/O. A 4-pole resonant state variable lowpass filter shapes the chaos with frequency, resonance, and feedback controls, all CV-addressable via attenuverters, while a hi-Z preamp lets you blend in external audio. Patch anywhere across 200 Dupont points for wild routing, trigger assignable performance buttons, or route through a global envelope—standalone in its aluminum case (34.8 x 13.7 x 5.5 cm, USB-C PD powered) or as a 68HP Eurorack module drawing 800mA on +12V.

Players dig its immersive drone immersion and patching freedom, though some note the raw instability demands hands-on tweaking to tame.
