Stem Player & Slow Downer
Simple multitrack player
$11.99
Hearing each part on its own changes how you practice. Stem Player & Slow Downer plays songs split into stems (separate parts), with per-part volume, mute, and solo.
FEATURES
- Per-stem volume, mute, and solo (drop the drums and play along, or listen to the bass alone)
- Slow playback (x0.9 to x0.5) without changing pitch
- Key change (±6 semitones), independent of speed
- A-B loop for the bars you want to repeat
- Markers to jump straight back to practice spots
- Waveform display so you can follow where you are
GETTING SONGS IN
Transfer wirelessly from a computer on the same Wi-Fi, or import a folder from the Files app. Stems can be made with the free Stem Separator (Windows / macOS — obbliworks.com/stem-separator) from your own recordings or purchased tracks, and any multitrack bounces you already have work too.
SLOW PLAYBACK QUALITY
If pre-rendered slow files exist, they are used (high quality); speeds without pre-rendered audio play through real-time conversion (standard quality). The app always shows which one you are hearing.
For band rehearsal, transcribing by ear, and instrument practice. One-time purchase, no ads.
