When beatmapping a whole song sometimes it works to perfection but sometimes it starts to go offbeat in the middle of the song all the way to the end. Is there anyway of fixing this so all the beats are on time? I know there's probably shortcuts around this like chopping the song up but I was just wondering if there was any other ways of correcting this that I just don't know about. Thanks to all!

It sounds like your tempo may be a little rushed or slowed as you get into the loop. You can manually move the points in Beatmapper to reign it back in.

My problem is that sometimes the points won't move or allow you to enable or disable them. I find that if I repeatedly try to enable and disable them, eventually they come around, but it is a frustratingly common occurance.

What I've done in the past is manually piece the track together. Play it until it becomes noticeably offbeat and cut it and adjust. The beatmapper isn't a failsafe feature.

What I do most commonly is to rebeatmap the file to make sure it's perfect. Start by choosing your first downbeat very carefully. Then, in the next screen, choose a good first measure, but it doesn't have to be absolutely 100% right on. Next, scroll way out through the song, checking to see that the beats are still on every 10-20 measures or so, correcting anomalies when you find them. These adjustments further out in the extrapolated measures make tiny adjustments to the first measures you defined, and will help you to make sure that everything is right on throughout the end of your track.

HTH,

Nate

This is what I do also but sometimes the adjustments at the end take the beginning off beat. I was just wondering if there was a simpler way around it. I mean keeping the whole song on beat. I guess I can try chopping the song at the point it starts to go astray and rebeatmapping the second part. Thanks for responses!

If your first downbeat is set correctly, and lining up the beats at the end cuts off beats at the beginning, then it is your track that is drifting in tempo. There are a few things you could try, chopping the track where it starts to stray may work fine for you. If it's still unacceptable, you might try the following longer method to map it:

1) Open the track you wish to beatmap in Sound Forge
2) Drop a marker at the first beat of every measure, from start to finish.
3) Looking at the ave distance between nearby beats, extrapolate/guesstimate the distances you need to use to drop markers
    out to the beginning and end of the track. This will include intros/outros or whatever may be left over. Be sure to put a
    marker at the very beginning and end so you don't lose anything in step 4.
4) Go to Special>Regions List>Markers to Regions - this will convert your markers to regions
5) Use Tools>Extract Regions to extract all your regions to a folder
6) Open ACID, paint your regions, in order, from top-left to bottom-right
7) Render this to a WAVE file at a tempo as close to the original as you can guess

You now have a beatmapped WAV file that maintains perfect tempo. The measures that didn't need stretching didn't change, and the ones that were off were corrected.

Hope this helps,
Nate

Thanks for the help! It seems rather tedious but I will give it a go. I'm curious to why some songs seem to go off beat so badly. I know sometimes glitches in the track can cause this.

Phenam,

There is a way to do basically the same thing in ACID only detailed here:
