In the piece the character is walking through what is meant to be a military funeral, so to compliment the bagpipes there is a snare drum line. The drum is actually a tom drum, but I have manipulated it in a way to sound like a snare drum. As you can see the EQ is kind of sporadic, with bands 1 and 3 dipping to frequencies, particularly at 500Hz. Then there is a vinyl distortion model in the signal chain. This is a unit which adds the crackle you hear when listening to vinyl records. And lastly the erosion device. This is what makes the tom sound like a snare more than anything. In this instance it adds in a lot of noise at 4.42kHz in a narrow band. Some of the snare lines have been added in sporadically and also reversed.
