Tempo Detection oddity

[ianaeillo]

The majority of my work must be converted into AAF and then into a .song file and with that comes some interesting quirks. Among them is a rather frustrating one. Often when attempting to use the Tempo Detection option, the file will just display a random tempo and not MAP, which is the expected behavior.

In my current case, I am opening an AAF file exported from Pro Tools. I am opening the AAF file in Studio One and everything loads as expected. Regardless of what the tempo is set to (in this case it is set to 120,) the tempo of every single file is read as 95. The tempo in the Pro Tools session is listed as 190, so I am assuming this is some sort of metadata issue. Has anyone run into this particular issue? It doesn't happen every single time I open an AAF, but that it does happen is annoying. Any way to strip the incoming wav of any tempo data?

Thanks

Ian

Looks like a double-time/half-time thing. 2 x 95 = 190

Right. That's why I mentioned it's some sort of metadata thing. It's reading that info from somewhere...but where, I'm wondering.

My guess is that it is actually detecting 95bpm as the tempo of the song, interpreting every quarter note in your arrangement as an eighth and so forth. Melodyne tempo detection allows you to double or halve the detected tempo before committing to it, so that may be your alternative route.

So the issue is that the tempo isn’t mapping. It’s reporting a number that it is getting from *somewhere* and I’m not sure how to get it to map and not report the tempo. The drums are not 95 bpm as they were performed with a swing. If it can create a map, I can create a grid to align to. My desire is to create a map to the drums. When I receive files from Studio One, I can accomplish this. But when I’m receiving files from a different DAW it doesn’t work. Just seeing if I can get it to map.

Note that 'Map' only appears for varying tempos. When mapping a song with a steady tempo it will not say 'Map' but simply state the single tempo it detects. So I still believe that Studio One is detecting that 95bpm, and swing can be on eights as it can be on quarter notes. It is exactly for these 'both correct' situations that Melodyne allows you to double or halve the detected tempo.
