The effect blends a Robot modulation engine with an adaptive Butter reverb and Chipset digital texture stage into one fast, playable interface. You get instant movement from subtle pulse to experimental wash while the built-in manual and factory presets speed up the creative process.
Robot Butter runs as both AUv3 effect and standalone app on iPhone and iPad (macOS hosts the plug-in only). It works as an AUv3 plugin inside AUM and other compatible hosts, adding vocal movement, guitar widening, or drum bus animation to any position in your chain.
