Change the Key to Match Your Voice
Songs are written in whatever key the artist chose — your voice lives in its own. Karapella lets you raise or lower any stem you pick (karaoke, acapella, instrumental, or an individual instrument) by up to 6 semitones, with a fine-tune quarter-tone mode for precise control. The key you choose carries through to the downloaded track and to any karaoke video you generate — no need to adjust it twice.
