You can set the scale and octaves that the plant has available to play directly in the device. Go to the scale screen of the PlantsPlay app, select the scale and octaves and tap on the central logo icon. You will see the notes and octaves stored in the device through dots on the scale and with numbers near the octave fold. In the settings menu of the PlantsPlay app, you can choose whether the app should play with the notes and octaves stored on the device or with those in the app. Every time the device is turned off, it resets with a chromatic scale and all octaves.
