[SOLVED] Inexact timestretch in Cubase SX 3 (example included)
Hi guys!
Is it just me, or is the timestretch-function in cubase SX3 very inexact when a sample is processed? I have used SX2 for several years without any kind of problems and I switched to SX3 some time ago. But almost every loop I stretch is very innacurate. Even if it is like 4 bpm's difference, the tempo isn't constant after stretching. Let's say I have a 128bpm 4bar loop and stretch it to 133bpm. In many cases even a 4bar loop lag in tempo at many places in the loop. I find this problem very strange.
Have anybody else noticed this?
I've uploaded an example of what I mean.
First part is a 128bpm loop together with kick sample.
Second part is the same loop but stretched to 135bpm together with the same kick underneath.
Hm, no? Where is that option? Over the years I've timestretched in cubase, the only thing you have to do when timestretching is use the timestretch tool and drag the end of the sample to the bar you want to stretch it to!

Double click on the WAV and an edit window will come up. There's a little music note icon above the wave form. Click on that and it'll ask you for the WAV's original BPM.

You are better of using the "audio-->timestretch" function, and try different settings there, which is also were u can input the Original BPM of the sample.

Yeh, I tend to do that, too. It gives better results, is more stable, and is easier on the CPU. Only problem is that it's a permanent fix. So if you want to change the BPM of the whole track, WAVs that were already time stretched will start to develop artifacts.
try changing the time stretch algorithm setup in file/preferences.

Alanzo and Subtle, thank you very much! That worked like a charm!!
Good it worked, but still. Pretty strange that I have to do that,
since it have always worked fine that usual way in the previous SX versions. Anyways, glad it works now! Thanks! I didn't know about that function wich you set the original-bpm to the sample! That's great! Since it's not very fun when I've stretched stuff before and I feel that I want to change project-tempo and I have to stretch the samples again from there! awesome!
Dannib: thanks for the tip, but it works now!

It should be noted though, that when timestretching in Cubase the result will never be 100% accurate, if you zoom in the very end of the sample you just timestretched, you will see a slight gap, which will be noticable once you start duplicating many blocks of the sample in a row, so use the glue too to fill the gap if needed.
