A real-time, glitch-free virtual analog synthesizer, written from scratch in Rust
Rusted Moog is a real-time, glitch-free virtual analog synthesizer — written from scratch in Rust. It’s a Minimoog-inspired 3-oscillator polysynth with a Moog ladder filter, “born from a Python synth that couldn’t stop clicking”. It started as VOOG, a synth written in Python + NumPy. It sounded great — until you played a chord. Then it clicked, popped, […]Anne Barela
