I've been making music in Logic for a while and just recently began recording vox. I tried using the tracks in the arrange window of logic 9 while making songs and I dont use an external hdd, which some people see as a bad idea, but I have done it. Now for some unknown reason I cant get any vox to lay right. I've had seasoned vocalist come to record and they say that their vox are too fast on play back and trying to nudge the track a little won't fix no matter how zoomed in and cut up I can get them. If anyone has any suggestions please let me know. Thanx

If you want a fix for this, you will have to be a little more precise than just saying "it's too fast". Try to get hold of an external sine-wave signal generator, set it to 1KHz and record a track with that as though it were a vocal track. On replay, adjust the generator frequency so it matches the frequency of the replayed sound, then tell us what the adjusted frequency is. Also listen to see if the replayed sine wave is continuous, or has clicks and blips that might correspond to missing samples in the original. Is it exactly the same each replay? How does it look as a waveform on the screen?

Only by eliminating the uncertainties of normal vocal and/or instrumental sounds can you get a handle on this type of problem.

I don't use logic so I have know idea how it resolves things with that DAW but could you have changed the resolution in between the making of this song? Is this happening to all sessions from this point on or just the one in question? I don't think its a buffering issue when the tracks are out of pitch sync with each other. It really sounds like some bits are tracking in at one rate and the bed tracks are locked in at another. This is usually really noticeable but... maybe a plugin or something on the vocal tracks that has a bit rate ?

Possible tempo automation or pitch control/correction you tweaked and forgot about it ?

I hope no one is using a HD 24 at 44.1 kHz? You know the clock is not accurate on that. And who knows, there may be similar problems with other pieces? Are you using the same bit depths? The less mathematical conversions the better. Most multitrack software & hardware of the digital kind, have the ability to slip and slide the tracks. Does a simple slip help? It's either rushing or lagging I would imagine?

I had a smashing time recording some tracks recently. Basically our church band was all off on holiday at the same time, and it was going to be pre-recorded. When I set up to record some guitar parts, the guitarist couldn't lock to the key of the piano part (recorded earlier; adding guitar was an afterthought).
What happened? The bleeding sample rate had set itself to 48K and the track was playing faster than it should've, having been recorded at 44K. Good thing I keep a hex editor and a reference of what to fix. Some files had gone totally wonky and it was all a mess.

And the funny thing is it's still subtle - I didn't realise it was too fast, but it was definitely off-pitch enough from the guitar. It's only a case of a 6% stretch or so. Not a massive amount if you're not listening for it, I find.

No, 8% stretch.
