Could someone please go into a little bit of detail about how to set up 
the programmable knobs. Heres a list of things I want to do with the. 

-Adjust the ADSR parameters of the prestets
-control the effect parameters i.e feedback, var ect
-note ranges, this would be really cool! If any one hasnt thought of 
this yet imagine the possibilities i.e &(*&king with basslines.

I know it has something to do with assigning each knob to the midi 
addresses of the parameter you want to control, but the manual dosent 
go into much detail about this. Thanks to you, who ever you will be.
