Arguments is a vintage-style test equipment plugin for tone generation and dual audio processing. It takes two signals and smashes them together using math derived from analog nuclear research processors. The results are dynamic, often unpredictable but always unique. Since each part of Arguments can run independently, it also works as a sonically rich test tone generator, as a complex distortion unit, or as a multimode filter. Arguments open nature rewards exploration, the presets are a mere suggestion for you to jump off from.
