these are used to slow down the response of the circuit and it gives the
circuit a bit more of a natural vibe so instead of the sound dieing quicky

tail end. this essentially gives it a slight decay envelope that can be
described as rubbery or woody. about 3 minutes into this video, you get a
great example of the sound.
