Fail the pair check before you spend a free try

MashupMaker runs a pair check before stem separation. A tempo gap over 12%, a key gap over 5 semitones, or an unreadable tempo rules the pair out and nothing is charged.

1. Use the free Key and BPM Finder on both tracks first.
2. If tempo differs by more than 12% or key by more than 5 semitones, pick another pair.
3. Only then upload MP3, WAV, M4A, OGG or WebM and tick the rights box.

An uncertain key read still gives the mix, with a note to nudge the vocal a semitone. Open the Key and BPM Finder or MashupMaker.
