Hi delicado,
thanks for bringing up this issue. I respond to your English post because more people may read it.
Sorry for our late feedback. We did a deep dive into the chord detection mechanism and confirm your observation that with the chord detection redesign which was done with version 2.6 in 2010, the chord detection actually became worse in some situations compared to previous versions. In Composer 3 (current release 3.0.1) this software is the same.
All I can say as of now, that we are going to address this subject especially and will fix it. I unfortunately cannot confirm that with the next software distribution the corrections will be available but I promise that we will do our best (being a guitar player I am not satisfied with the current chord transcribtion results either
).
We are going to inform you here in the forum as soon as the fixes will be available.
