+1 for William's approaches - works for me.

Actually, I have not yet understood what a sigmund~ "track" is, the help patch does not say much. What is the difference between a track and a partial? Thanks again!

[PD] Mute certain partials (sigmund~)?
I am trying to mute every even partial of an integer series of partials from a harmonic oboe sound tracked with [sigmund~]. I find that this is non-trivial as it is hard to determine -the order of increasing frequencies (sigmund orders them by strength) -which partial is the lowest for a harmonic sound. Does anyone have a good idea how this can be done either in realtime or offline (via tables perhaps)? Thanks!
