EXS 24 Logic Sampler Users Group

I was recording an EXS track in Logic and using the mouse to turn the 
Filter knob of the EXS24.  Logic recorded the sweep exactly the way I 
turned it, but that's the problem!  It wasn't a smooth turn 
(remember, I'm using a mouse!  Cut me some slack!) - so I opened 
Hyperdraw in the arrange window and I can see the un-even jagged 
sweep.  How can I smooth it out?  

Thanks,
Mark
