Rihanna - Love in a Hopeless Place HELP!

In Rihanna’s song “Love in a Hopeless Place”, there’s a sound in the build up that I’m trying to replicate. It sounds like a saw wave that’s modulating in pitch, but I’m not sure. Can someone help me?

Sounds like trance leads to me for the main element to the break…br

The other sounds on the build that is pitching up sounds like a basic dubstep preset you can find anywhere. br

If you know where to get all kinds of presets you should have no problem. Just go through a lot of Dubstep presets and listen for the tone. Also, try bringing the keyboard up in octaves to match the octave that the sound you’re looking for so it’s easier to hear.br

Goodluck.br
