Ahhh!!

I re-read the original post and it could have been understood to mean a change of a modulation parameter every time a new note is played. So I misunderstood your misunderstanding.
For that case, what you suggested would be fine of course.

Thank you all for all the comments and suggestion. Spogg described the problem I need to solve correctly. Adam assembly code is spot on for my use. Very elegant and simple and as he said using stage 0 there is almost no cpu uasage. So another special thanks to adamszabo.
