Try using a phrase sample with an LFO with a high Rate (like 05.00-10.00 depending on length of the sample) on the Pitch parameter. Emulates a power off effect like on a turntable.
Yah, you just need to "play" a bit with it... Put some filters on your sample and run a LFO on it... Remember that (i.e.) rate: 00.24 means 0,24 bar and (i.e.) rate 01.00 is 1 bar - which means that the LFO effect will happen within respectively 0,24 bar and 1 bar. Don't know if this makes sense, it's kinda hard to describe how it works.
