rslider for waveform~

Hello all,

Just a quickie question.
I am messing around with a sample mangling patch, involving waveform~ and also rslider.
But there is one thing i am having a bit of trouble on.

I want to integrate rslider with waveform~. i know you can mess with waveform~ a lot easier with samples than rslider, but i like rslider.
But the problem i am having is, how do i get rslider to expand to the same loops length as waveform~. i have looked on the tutorials and even archives, but can not seem to get anything what i want. I did try the Max tutorial involving movie sequencing. But am still stuck.

That was about it...
