Hi. How can I resample in same tempo as sample (that i have before resampling)? I tryed to adjust it with "start/end level" but there is a delay.

The BPM of a sample set in TIME/BPM button is purely a 'how long is this sample?' reading. Unless you're a robot and can resample at the exact start/end points of what you're resampling, it's not going to know this. The SP404 sees it as a brand new sample and then sets BPM according to how long it is and where it might detect patterns in the audio to confirm it's guess as to the BPM.

Long story short, you must re-mark the sample as what you resampled from and then set the BPM value again. If you don't re-mark the sample, the BPM feature won't act the same way it did on the pad you resampled because the length of the sample (including the silence and 2+ frame delay from at beginning of your sample on the resampled version) is different.

Hope this helps. Theoretically, you should be able to get it back to the correct BPM setting without it stretching, but I've had difficult time with this, so if it was stretched at all on the original pad, I don't bother with the BPM after that. It's the BPM it should be! All I do is just trim it up with the markers so it loops right.
