I frequently use a live guitar in my PD patches, I route it through the mic input [adc~]. But now I am facing a problem, that you might help me with.
I am interested in detecting in PD the moment of hitting the guitar strings with the hand, e.g. like using a hand to drum on the strings.
It is a very percussing sound, similar to a snare hit.
I would like to detect this hit on the guitar strings in PD (coming through [adc~]) and use it as a simple bang trigger.
It would be easy to use the [fiddle~] attack output, but I don't want the trigger on any other guitar playing event (e.g., chords, notes ...) except on this percussive hit on the strings.
Do you have any guidance on where to start to tackle this problem?
I don't have the slightest idea where to search for information regarding this topic.
