The Filter function from the effects menu is probably not going to be added back, since its functionality is duplicated by the multiband equalizers. The 3D-spectrum analyzing tool will probably not be added back either, since it didn’t seem to be used by sufficiently many users. I believe that all other functions that were present in Amadeus II have been replaced by equivalent (or more powerful) functions in Amadeus Pro. If you disagree, please let me know.
