Analogue-sequencer

So the p3 has a 303 type slide feature? You need a cv converter, though. 
A pro-solo already has a slide feature. So how does this work? Also, Can 
I get 4 cv sequences going from a single track on the p3 w/ cc messages? 
What would be a CV good box for handling this?  Basically, how would I 
mimic a Milton sequencer w/ slide?
Thanks
