any know any add ons or what can be used to remove annoying hiss noises when sampling?

there's a few ways to do this:
roll of the problem freq's or use a noise gate or reductor.
also if your talking about vinyl hiss it's sometimes quite nice to keep it in.
But if its hiss from recording you have to find which instrument is making it and moving it aroun the room until it stops.

EQ8 - try to find the hiss frequencies with narrow positive (high Q) peaks and then reduce that peak as much as you can in EQ8. Also, you can add GATE and gently set the treshold to cutoff the silent portion of the sound.
