There is no reason what so ever why Beat Calculator should have been removed. Many users have been clamoring for reinstatement.
If Steinberg wants it hidden from the general menu, whatever, but make it possible so that it can be made visible through preferences.
This was fundamental in my production and absolutely ridiculous its been removed.
Beat calculator is a scientific and exact tool that analyzed events, be that audio or midi, and gave an exact bpm of selected events in relation to stated numbers of bars and also gives the option to set project tempo to such bpm. Whereas tap tempo is inaccurate and not what anyone who has been using beat calculator for decades wants or can use.
