i see... i have never done something in this direction using PD so I am 
discovering how to deal with namespaces, etc... And yes the idea is to 
make its use as transparent as possible. thanks for the tip

i know, i took this direction because i had a deadline  for this, 
students needed it for next week, and xgroove~ is what i use mostly to 
play around with samples. I would like to develop a better solution for 
the sound part, I saw a previous post about this issue
http://lists.puredata.info/pipermail/pd-list/2007-04/048967.html
maybe this would be a better direction to go?

indeed they help. many thanks!
