grumblebum is a stereo vst effect that uses the incoming audio to drive its internal synth. the results range from a subtle analog accompaniment, to wet analog sounds, to screeching distortion. try it on drums, vocals, leads, whatever. version 2.5 adds the randomizer, fixes the random droning bug, and updates the user interface!
