What is B21 Stage Time?
B21 Stage Time is a performance-focused player. Build a set from Apple Music playlists or import audio from Files (MP3, M4A/AAC, WAV, AIFF, ALAC). Keep the screen awake on stage, scrub precisely, and control playback with clean icon-only controls.
Troubleshooting
No sound or playback doesn’t start
- Check your device volume and mute switch.
- If the track was imported from Files, try re-importing (Files ▸ select audio ▸ Share ▸ Save to B21 Stage Time).
- If you selected an Apple Music playlist, DRM-protected items can’t be played by third-party apps.
- Try Clear all data (⋯ menu) and re-add your set.
Imported files play but disappear after clearing
Clearing all data removes your current set and any imported audio from the app’s sandbox. Re-import from Files when needed.
Apple Music playlists don’t appear
- Settings ▸ Privacy & Security ▸ Media & Apple Music → allow access for B21 Stage Time.
- On Simulator, Apple Music library isn’t available—use Files import instead.
Screen sleeps during a set
Enable Keep Screen Awake from the ⋯ menu to prevent auto-lock while the app is foregrounded.
Silence calls/notifications
Use Airplane Mode or Focus ▸ Do Not Disturb before a set. The app can show an airplane-mode reminder banner on the home screen.
