for now, i did not use pressure or tilt.
the 1st thing to do is to use the pressure to have a 0 or 1 that can replace the grab parametter. (as for now there is a quick hack in order to make 
this instrument work).

then , i think the tilt could be use in diferent way : by exemple
-changing the feedback of the karplus-strong loop
-having a more complex sound input (maybe remove the pmcloud object)
-changing some physical mapping parametter
-...
