Microphone doesn’t work / no sound detected?
- Check that the app has microphone permission (iOS: Settings → Privacy → Microphone; Android: Settings → Apps → HarpMaster → Permissions)
- Quit and relaunch the app (iOS may kill the mic session in background)
- Play closer to the mic in a quiet environment
My harmonica isn’t in C key — can I still use it?
Yes. 21 keys are supported (Low C through High G). Open Settings and pick your harmonica’s key.
The detected notes don’t map to the right holes on my harmonica?
Check:
- Is the key correct? A G-harmonica set as C will show everything shifted
- Is the position correct? 1st position is default; 2nd position is typical for blues
- Is the tuning correct? Standard Richter vs. Country / Paddy Richter / minor tunings
iOS loses sound after returning from background?
iOS restricts audio sessions in background. The app has recovery logic: on returning to foreground, mic auto-restarts after 300ms. If it still fails, manually toggle the mic button.
What’s the difference between Piano Roll / Jianpu / Staff views?
- Piano Roll: Most intuitive — Y-axis is pitch, bars represent note durations
- Jianpu: Chinese numbered notation — 1–7 degrees with octave dots and accidentals
- Staff: Standard Western notation with key signatures and accidentals
What do the three practice scores mean?
- Pitch (40%): How close your pitch matches the target note
- Timing (40%): How close your attacks are to the beat grid
- Hit rate (20%): Whether you successfully triggered the note at all
