Reply to Lexicon PSP 42

I have downloaded the demo version of the Lexicon PSP 42 delay , I have it running in Abelton but not sure how to work it , turned all the Knobs and buttons trying to get a simliar sounds that Richie Hawtin uses but get nothing like it .
Does anyone have it and know how it works , I have read the manual but didn't get anything from it . Also is it possible to midi map all the knobs and buttons to a controller .
