[chuck-users] ADSR and gradually shift pan from left to right and back

Hello ,

Thanks a lot for your help.  I still have some general questions and some about the program that follows:


  1.  Where can i find a chuck editor  with the possibility to find words and replace them (all) and that also gives the colors for reserved words etc.
  2.  Is there a way to debug line per line to discover logical errors?
  3.   i discovered by accident that sometimes i can use "p.puf" but on other occasions i have to write "p.buf()" why is this?
  4.  in the program hereby, is there a way to have the pan do it's job independantely from the note-envelope-flow? to go faster or slower?
  5.  When i run this program it does what i want but i can't figure out why it says 2 times "p.pan = 1.000000" and 2 times "p.pan= -1.000000" (see below)

Thanks !!

Herman
