I'm trying to use Applio to create covers and I'm having a problem with the pitch. I don't understand why, if I keep it at 0, it doesn't play a cover with the same key as the original. Why is that? At zero, shouldn't it be the same key, and if I go up one, does that mean I raise the key by a semitone? I had to raise the key by two semitones, but to get the desired key, I had to raise it by four semitones. I don't understand this problem.
