I came across this "Riser"/"Uplifter" which is frequently used in trap music. But I don't really know how to create it.. All I can guess is that the sound has a volume envelope to it which has a fairly fast cycle of going up and down which itself speeds up over time, and then there's a rise in pitch, could be white noise with a bit resonance added to a wavetable in a synth but I'm not sure.. And I don't really have a clue what effects may be used, can you help me out with this sound?
Example 1: (1:00-1:05)
Example 2: (0:17-0:22)
Thank you :)
