I will be investigating ways to isolate individual harmonics from a mic’d trumpet player, who will be sustaining a note. The idea is to be able to capture this audio in max and somehow separate the individual harmonics present in the sound, and then hopefully map them individually to a midi controller pad, so we can demonstrate how the trumpet sound/note being played is actually composed of individual sounds.

Has anybody tried anything similar, or can see any obvious flaws with my idea?

Thanks in advance,
Benjamin

You can access it on the ZiMT website as part of the Klangpilot 3 environment (http://www.mdw.ac.at/zimt/downloads.html). Unfortunately it is not documented yet, but as the attributes can be seen in the object inspector, with some experimenting it should be quite straightforward.

You wish to decompose the sound into its harmonics?
I was thinking something like using a pitch detector to recognize the fundamental pitch, then use this note (frequency) to calculate the harmonic series for this pitch, and use this to configure automatically a series of filters (for example reson~ inside polys).
Tell me what you think.

best wishes
