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 !!
