TLDR:
The trusty old Beat Calculator was very reliable and accurate. The new replacement is unreliable and inaccurate as it is relying on the users ability to perfectly time the 2 last taps down to the microsecond.
Dear Steinberg,
A decision was made to remove the Beat Calculator in Cubase 13 without something to replace all of its uses. This was met with strongly worded complaints on the forums and while you initially directed users toward the new and less capable tempo-tap feature, or the old Tempo Detection panel (which gives a good reading as if by the whims of a playful coin toss) you eventually made an update addressing the complaints: the 13.0.20 maintenance update. Forum threads on the topic were then swiftly closed and/or marked as solved.
While the reasons for removing the Beat Calculator in the first place remain a mystery it is clear that the update still didn’t bring us back to parity with the functionality of the beloved (and perfectly working) original.
The good old Beat Calculator had the capacity of being highly accurate. It was built in such a way that the longer one tapped along to a beat the more accurate the reading would become. The trusty Beat Calculator was designed very cleverly indeed: by dividing the number of beats tapped and the time elapsed since the first tap, one could be certain that no matter how unusual of a tempo one tapped along to, if one simply tapped long enough the reading would steadily approach the true tempo with accuracy down to a decimal. No need for more than one attempt.
Anyone that has used the new tempo tapping feature knows that the same cannot be said of it. No matter how long one taps along to a beat, the reading will jump around and not at all get more accurate over time as it’s overshooting or undershooting its mark by large margins. One will have as bad of a reading after 20 full seconds of tapping along as after just the first two taps.
See, the new tempo-tap feature is designed in a much less precise way. Instead of taking all taps in to account it is naively relying on the users ability to perfectly time the 2 last taps down to the microsecond. Since this will inevitably fail to give the correct tempo for most users, it will then instead try to compensate by rounding the reading to something that looks like a more “reasonable” tempo, like a whole number, or a whole number and a half etc.
The fundamental problem with this is that you will get multiple readings as you tap, and they will all look reasonable, but you have no idea which one to trust, so you basically have to guess; take one of them and see if it’s the one and if it isn’t: increment or decrement until you’ve found it - kind of doing it by hand in a sense. A much more involved process and much less efficient. The Beat Calculator would give you one accurate answer you could trust, the new replacement will get you in the ball-park with multiple answers you can’t really trust. That’s a surprisingly big difference in ergonomics.
It’s a bummer having to open a web browser or a third party app to do something so very simple and fundamental that was previously easily done within Cubase itself. Please bring back the Beat Calculator and/or better yet: add a mode to its replacement that behaves in the same accurate way. Simply displaying a reading that stabilizes over time, approaching the true tempo as one taps along. Over the coming years this will no doubt add up to a lot of saved time and frustration.
Thank you!
