Tap Tempo on Mac registering too slow

[danryker]

When I tap the tempo in the stand-alone Mac app using trackpad, it sets the tempo too slow. If I tap in a different app, it's accurate, so I don't think I'm just a lame tapper. :-)

Tap to tempo is simply:

• averaging (how much data/taps you log and how you average them)
• and smoothing (how extreme do you filter).

So not all apps are the same of course.

How I test it usually.

• Play a song (YouTube, Spotify, etc)
• Start tapping with the beat. about 4-6bars.
• Usually I get ±1bpm offset (Eg if bpm was 118 I'll get something like 117.7 or 119).

Since this is all open-source you can review the code.

Personally with some DAWs I had more fluctuation in the "methodology". and my use-case was when I'm in a rehearsal and someone plays, I try to "catch" his tempo for us to play at his pace.

I think I found a clue as to what is going on . It is accurate the first time I use ’tap’ after opening the app. But on all subsequent taps, it is too slow. For instance, on a song that should be 122 BPM, I get about 105 on subsequent uses. But it is accurate on the first use. If I restart the app, it is accurate again on only the 1st use. This is true in stand-alone and an an AU plugin in MainStage. I also just figured out that if I tap way too fast (like 220), and then try it again, it will be pretty accurate. Thanks for considering this.
