It probably seems like I’m never going to get to the part where we do the actual warping. Well, this tip is no exception. One more piece of background info. It’s all worthwhile. Promise.
Take a look at the drum hits below 1, 1.2, 1.3 and 2. The hits at 1.2 and 1.3 look almost perfectly aligned with the grid, but by the time you get to 2 (the first beat of the second bar), it’s clearly not aligned properly – and it only gets worse as you move further into bars 2 and three. This is how it goes when something is almost warped properly – at first it’s pretty close, but the further into the track you go, the worse it gets.
Now take a look at the Seg. BPM box. This value specifies the original tempo of the audio.
This value isn’t quite right. If it was right, the waveform above would line up to the grid properly.
Where did this value come from? Take a look at Live’s master tempo:
When I tapped in the tempo for this song, this is the value I ended up with. With Auto-Warp Long Samples turned off, Live just uses the current master tempo as the original tempo of the audio.
