If you're seeing a missing files prompt, make sure you have the entire Logic Pro sound library installed and are using Logic Pro 10.8 or above.

If your instruments aren't appearing in the browser, refresh the browser and search again. If they still don't appear, make sure you followed the installation protocol properly and placed the files in the correct locations.

You can use our instruments to create any musical work individually or collaboratively; however, you cannot use our instruments to create commercial virtual instruments, sample packs, or other products of a similar nature. 

We allow project sharing in a collaborative context, but this does not grant your collaborator a unique license to the instruments used in your project. If they wish to use the instruments in separate projects independently, they will have to purchase their own license. 

If you exclusively use your own sample content within our instrument designs, you can create and distribute sample packs in the form of .wav files, but you cannot sell patches or presets utilizing Doppler's proprietary instrument framework without our written consent.

Yes, we offer a risk free 14-day return policy; however, due to the digital nature of our products, if we suspect suspicious purchase activity, we maintain the right to deny any return at our discretion.
