## What is PlayStems?

PlayStems is an on-device multi-track stem player and AI audio splitter for musicians, vocalists, and bands to practice, rehearse, and perform with complete mix control.

Import multi-track stems or split any stereo song directly on your device into independent vocal, drum, bass, and instrument tracks. Rehearse complex sections, isolate parts to learn by ear, or create backing tracks for live performance—all with zero audio uploaded to the cloud.

MULTI-TRACK MIXER & REHEARSAL TOOLS
• Synchronized multi-track playback with rock-solid transport stability
• Per-stem mixer: adjust volume, solo individual parts, mute tracks, and tweak stereo pan
• Variable tempo & pitch: slow down fast passages without changing pitch, or transpose keys
• Precise waveform scrubbing and loopable marker ranges for repetitive practice
• Master level control and clean library organization by title and artist

ON-DEVICE AI STEM SPLITTING
• Separate stereo tracks into vocals, bass, drums, and other instruments
• 100% private: audio processing runs locally using your device's Neural Engine
• No cloud servers, no account required, and no internet connection needed to split

### 1/5 — Media Player is broken

*2026-09-01*

So I was able to upload my song stems into the player and that was an easy straight forward process. I spent the extra $4.99 to unlock the full version. When I pressed the play button it played like it should, however, when I hit pause it does nothing, when I bring up the mixer after trying to pause it, I have no control over the mixer. After hitting the pause button I lose control over all buttons and the only way to get it to stop playing is to completely close the app. I like the app, I would like to use the app, but if I cannot pause it and then can’t do anything with it, then it’s not worth it even if it’s free.

**Developer response:** I just released a new app version 1.2 and hope your issues are resolved with this. Otherwise please use the feedback button in help to send me some more details. Thanks!
