I would like to get some help concerning the following issue.

I am having a changing flonum. The number moves like a wave (EEG). I would like to receive a bang when the wave reaches it's peak point or even better if I could receive bangs while it is "riding the top of the wave". Please have a look on the attached picture, as it describes my wish more than my crappy English.

I had a look at objects like peak, peek~, peakamp~ but I could not use them for this purpose.

I guess I just need an object which sends out a bang whenever a changing number starts to decrease.

what's wrong with what you have? seems pretty straight forward, and it works...

ok, you are right, I will not worry much about it than...
