Modulix End User License Agreement

Terms of Use

Last Updated: October 2026

This End User License Agreement (“Agreement”) is a legal agreement between you (“User”) and UE Sound / Umut Erhan (“Developer”, “we”, “us”) for the use of the Modulix desktop application (“Software”).

By downloading, installing, or using Modulix, you agree to be bound by the terms of this Agreement. If you do not agree to these terms, do not install or use the Software.

1. License Grant

Upon purchasing a valid license key, UE Sound grants you a personal, revocable, non-exclusive, non-transferable, and limited license to install and use Modulix.

  • You may install and activate the Software on computers that you personally own and use.
  • You may not share, sell, distribute, or publish your license key.
  • The Software is licensed, not sold, to you. UE Sound retains all intellectual property rights, copyrights, and ownership of the Software.

2. Early Access / Beta Software Disclaimer

You acknowledge that Modulix is currently being provided as “Early Access” or “Beta” software. This means the Software may contain bugs, errors, or missing features. We strongly advise that you thoroughly test your setups, plugins, and MIDI configurations during rehearsals before relying on the Software in a live performance environment. UE Sound does not guarantee that the Software will be error-free or uninterrupted.

3. Free Trial & Refunds

Modulix includes a fully functional 14-day free trial. We strongly encourage you to use this trial period to thoroughly test the Software with your specific Mac, audio interface, MIDI controllers, and third-party plugins before purchasing a license.

Because you have ample time to ensure the Software works perfectly for your setup, all license sales are considered final and non-refundable.

If you experience an extraordinary billing issue (such as an accidental duplicate purchase), please contact support@uesound.com within 7 days of your purchase and we will review your request on a case-by-case basis. Payments, taxes, and invoices are processed by our authorized reseller, Gumroad. See also our Refund Policy.

4. Restrictions on Use

You agree not to:

  • Decompile, reverse engineer, disassemble, or attempt to derive the source code of the Software.
  • Modify, translate, or create derivative works based on the Software.
  • Remove, alter, or obscure any proprietary notices, copyright labels, or licensing mechanisms within the Software.
  • Use the Software for any illegal or unauthorized purpose.

5. Limitation of Liability

Please read this section carefully as it limits our liability.

The Software is provided “AS IS”, without warranty of any kind, express or implied. Modulix is a live performance tool, and while we strive for maximum stability, computer hardware and third-party plugins can be unpredictable.

IN NO EVENT SHALL UE SOUND OR UMUT ERHAN BE HELD LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE SOFTWARE. THIS INCLUDES, BUT IS NOT LIMITED TO, CANCELED PERFORMANCES, LOST GIG REVENUE, DAMAGED AUDIO EQUIPMENT, OR DATA LOSS.

Your use of the Software in a live, studio, or broadcast environment is entirely at your own risk. In jurisdictions that do not allow the complete exclusion of liability, UE Sound's total liability shall never exceed the actual price paid by you for the Software.

6. Privacy and Data Collection

Modulix communicates with external servers to validate license keys via Gumroad and securely report anonymous crash diagnostics via Sentry. We respect your privacy and do not collect personal usage data, keystrokes, or audio. For complete details, please refer to our Privacy Policy at https://www.uesound.com/privacy-policy.

7. Governing Law

This Agreement shall be governed by and construed in accordance with the laws of France and the European Union, without regard to its conflict of law principles.
