# Verb de Lion — End User License Agreement

**Last updated:** August 30, 2026

This End User License Agreement ("Agreement") is between you ("Licensee") and Frank Acklin / Störsender Studio ("Licensor") for the use of Verb de Lion ("Product").

By installing or using the Product, you agree to the terms of this Agreement.

---

## 1. Definitions

- **"Software"** refers to the Verb de Lion plugin application, including all scripts, interface code, and configuration files.
- **"Impulse Responses"** refers to all measured room responses, the derived working copies embedded in the Product, and the photographs and floor plans of the measured locations.
- **"License Key"** refers to the unique activation code provided upon purchase, or a Drums de Lion key that covers this Product (see 3.3).

## 2. Dual License Structure

This Product consists of two separately licensed components:

### 2.1 Software — Open Source (GPLv3)

The Software (HISE project files, HiseScript code, XML configurations) is licensed under the **GNU General Public License v3.0** (GPLv3). You may freely use, modify, and distribute the Software under the terms of the GPLv3.

Full license text: https://www.gnu.org/licenses/gpl-3.0.html

**Where to get the source.** The corresponding source for the Software, including the build instructions and the exact HISE commit each release was built from, is published at **https://stoersender-software.com/en/source** — free of charge, no license key required.

### 2.2 Impulse Responses — Commercial License

The Impulse Responses are **proprietary** and licensed under the terms below. They are NOT covered by the GPLv3.

## 3. Grant of License (Impulse Responses)

Upon valid purchase and activation, Licensor grants Licensee a **non-exclusive, non-transferable, perpetual license** to use the Impulse Responses under the following terms:

### 3.1 Permitted Uses

- Use the Impulse Responses in **unlimited commercial and non-commercial music productions** (songs, albums, film scores, game audio, podcasts, etc.)
- The resulting works may be distributed, sold, streamed, and broadcast without additional fees or royalties
- Install and activate the Product on up to **three (3) computers** owned or controlled by the Licensee

### 3.2 Prohibited Uses

- **Redistribution:** You may not share, resell, sublicense, or redistribute the Impulse Responses in any form — whether original, modified, resampled, repackaged, or as part of another reverb, impulse response library, or virtual instrument
- **Isolation:** You may not extract, export, or make available individual impulse responses from the Product for use outside of the Product
- **Transfer:** You may not transfer your license to another person or entity without written consent from Licensor
- **Circumvention:** You may not share your License Key, use a key issued to someone else, or otherwise obtain, access or distribute the Impulse Responses without a valid license of your own

> **Note on the Software.** The Software is licensed under the GPLv3 (see 2.1) and you may study, modify and redistribute it — including any part that handles activation. The restrictions in this section 3.2 apply to the **Impulse Responses**, which are not covered by the GPLv3, and to the license keys that grant access to them.

### 3.3 Included with Drums de Lion

A valid Drums de Lion license also covers Verb de Lion. Both plugins may be activated with the same key, and doing so on one computer consumes one (1) of the three activations, not two. No separate purchase is required.

## 4. Ownership

The Impulse Responses were measured at **Gare de Lion, Wil, Switzerland** in August 2026, before the venue's renovation. All measurements, photographs and floor plans remain the intellectual property of Frank Acklin / Störsender Studio. Purchasing a license grants usage rights only — no ownership is transferred.

## 5. Activation

- Each License Key permits activation on up to **three (3) computers**
- Activation requires an internet connection
- License validation may occur periodically to verify activation status
- A failed or unreachable validation does not disable the Product; only an explicit rejection by the license server does

## 6. No Warranty

THE PRODUCT IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. LICENSOR DOES NOT WARRANT THAT THE PRODUCT WILL BE ERROR-FREE OR UNINTERRUPTED.

## 7. Limitation of Liability

IN NO EVENT SHALL LICENSOR BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM THE USE OR INABILITY TO USE THE PRODUCT.

## 8. Termination

This Agreement is effective until terminated. Licensor may terminate this Agreement if Licensee breaches any of its terms. Upon termination, Licensee must destroy all copies of the Impulse Responses.

## 9. Governing Law

This Agreement is governed by the laws of **Switzerland**. Any disputes shall be resolved in the courts of the Canton of Thurgau, Switzerland.

## 10. Trademarks

Gare de Lion is the name of the venue where the measurements were made. It is used here solely to factually describe the origin of the recordings. Verb de Lion is an independent product and is not affiliated with, sponsored by, authorized by, or endorsed by the venue or its operators. No partnership or endorsement is stated or implied.
