The midi monitor shows nothing abnormal:
Here I made some test: I gently blow without tongue attack, like several short crescendo:
With this preset it’s not so audible, but on some others, when I’m really searching the purity of the sound, it’s annoying to finish a decrescendo with all this noise.
The same sound but with a 20db boost at 70Hz. Can you hear it?
The same as precedent but with the Breath CC message rate set to 125Hz in place of 500hz.
