More information

The App Store may display an app that should have been purchased as if it has not been purchased.

The App Store may not show that the app has been purchased on a different device than the device on which the app was purchased. (For example, when you purchase an app on an iPad and then install it on a Mac.)

However, as long as you are using the same Apple ID, you should be able to install it for free for the second and subsequent installations, even if it is on another device.

If you continue with the purchase process, the App Store should eventually confirm that you have made the purchase and you should be able to download the app for free, even if it appears as if it has not been purchased.

If you have further questions or concerns, I encourage you to contact Apple Support.

Synthesizer Engine

Mersenne is a polyphonic synthesizer incorporating frequency modulation, noise, resonator and effects.
