Hi Rogerio:

It is a quite common problem to have difficulty reading the 8th partial
of F3. The reason is that the hammer often strikes the string at its
eight partial node. The node is the part of a string which normally has
less or no movement. The loop is the part of a partial which makes the
sound and is the space on the string between the nodes. Well, when the
hammers strikes the string at a nodal point, it tends to kill that partial.
The simple solution to this problem is to pluck the string half way between
the hammer strike point and the upper termination of the string. You will
get a very clear indication of the LEDs with that simple technique.

I cannot at this time relate to what you are seeing at the note D6. 
Obviously you are not talking about FAC in regard to this note. Perhaps you
could write a little more specifically about that note in a future post.
