what is this riser called / how do you make it

[setzin]

whats up everyone this is my first post here. i used to lurk djforums a bit but its been a while since ive seen that site up.

question; from 1:30 - 1:40 in http://www.youtube.com/watch?v=RSPefIBg79k how do make that type of build up with the pitch rising? and what is it called? i havent been able to figure it out yet. i use ableton as my DAW.

another example just to be clear would be http://www.youtube.com/watch?v=LEr5NJLpXXQ @2:22 where the riser comes in until about 2:28

thanks

Sounds to me like a synth sound and then automated with a pitch bend.

its as simple as this, or just a synth with a pitch evelope with long attack.
