Microphone Use
The microphone is used only when you press the sampling control to record a sound into the sampler. K.O. II does not require an account or cloud service.
Export
Recorded output is exported locally as an audio file through the iOS share sheet, so you can save it to Files, AirDrop it, or send it to another app.
Troubleshooting
- If you cannot sample audio, confirm microphone access is enabled in iOS Settings.
- If playback is silent, check device volume and connected Bluetooth or AirPlay outputs.
- If export does not open, try closing and reopening the app, then record again.
