Enable Tempo Sync to preview at your project tempo. Downloading with Tempo Sync enabled converts the file to that BPM, ready to drop into your session with no manual adjustments.
Set a Key to re‑pitch previews to that key. If you want all samples to preview in the key of A minor, first set your project key to A, then filter for samples in the Minor scale. Now all samples you preview will automatically, and instantly, snap to the key of A minor.
