LFSR lofi oscillator

AT Legio is a stereo oscillator based on the algorithms of Ataraxic Translatron, the first module Noise Engineering ever made. Inspired by the Atari VCS chip, AT uses a linear-feedback shift register to create chiptune-esque tones ranging from simple and square to harmonically complex and noisy. The Legio version takes things further with the addition of a second modulating oscillator, a stereo chorus, and a stereo audio input for ring modulation, dynamics mapping, or external mixing.
