Record your voice or any sound and play the piano with that sound. Press the top-right button to start recording and release it to stop recording.

In Free Mode you can record and play as many sounds as you like, and use the modifier buttons for a 10 seconds period in order to test it.

- Chord -> plays 3 sounds per key at once.
- Double size -> enlarge the size of the keyboard
- Smooth -> override the keyboard pitches and use a real-time pitch selector
- Keep length -> use the rate property instead of direct pitch modifier

The ReTune Pro mode in-app purchase allows you to use the modifier buttons with no time limit. Also, the display will show the note name instead of the timer.
