Hello again, If you remember I had a problem with the filters for a mezzo-soprano piece. I have solved the problem. Once again, I have a question (I hope it is not disturbing anybody): How to put the signal "in" (mic) onto a f table? GEN accepts sound waves but is there a way to replace a GEN by in? I am asking this because time stretching only works with f tables (sndwarp) or pvanal files isn't it? Thank you for all your help.
