Simple Drones

Simple Drones is an app that functions as a simple tool to play a continuous note. You choose the root note, and the sound plays steadily in the background. The app also lets you control overtones, higher tones that sit above the main note and change how the sound feels. Use sliders to adjust the volume of each overtone. Turning them up makes the sound richer and brighter. Turning them down makes it softer and more pure. The app is useful for music practice, relaxation, and creating steady background sound.
