Nearing the end of soundtrack 2 a ride cymbal is introduced. It was to introduce a layer of mania near the end of the piece. As the madness builds up towards the end, you feel like nothing more can be added to the soundtrack to make it harder to listen to. That is when the ride cymbal is introduced. It is a long reverberant ride with a mad long tail on it, and you can tell by the sound of it that it is a large, dark, heavy cymbal. Here it is below.
You can see below that I have rolled off the EQ on the ride cymbal, just to keep that dark washy uncomfortable feel of the cymbals. There is also a chorus added, which combined with the natural sound of the cymbal makes a zapping sound. The dry/wet is at 50% so we hear the original and affected cymbal together at the same rate.
