Please read the full text below for complete legal terms.
- 1. LICENSE GRANT
This End User License Agreement is between you and Expetri (the "Licensor").
Polar is the merchant of record and authorized reseller for purchases of the Software. The Licensor supplies and licenses the Software and provides product support. Purchases, payments, taxes, and refunds are governed by the applicable Polar buyer terms.
Subject to your compliance with this Agreement and any applicable purchase terms, the Licensor grants you a limited, personal, non-exclusive, non-transferable, and non-sublicensable license to install and use the Software solely for lawful music production, sound design, performance, and other audio-production purposes.
The Software is licensed, not sold. No ownership interest in the Software or any intellectual property of the Licensor is transferred to you. All rights not expressly granted in this Agreement are reserved by the Licensor.
- 2. AUTHORIZED USER AND THREE-DEVICE LIMIT
One license authorizes use by one natural person (the "Authorized User") on no more than three computers or other compatible devices owned or controlled by that Authorized User at any one time.
An installation in a virtual machine or similar virtualized environment counts as a separate device. A business, school, studio, or other organization must obtain a separate license for each natural person who uses the Software.
You may replace an authorized device, provided that you first deactivate that device through the Polar Customer Portal and then uninstall or permanently disable the Software on the device being replaced. Uninstalling the Software alone does not release an activation slot. You may make one additional archival copy solely for backup or disaster recovery. The archival copy may not be used unless it replaces an authorized installation.
Initial activation requires an internet connection. The Software periodically validates the license with Polar. After a successful validation, the Software may operate offline for up to ninety days if Polar cannot be reached. An expired, revoked, invalid, or mismatched license may disable features reserved for the full version.
You must not share the Software, a license key, installer, account credential, or other access mechanism with another person.
- 3. OWNERSHIP AND INTELLECTUAL PROPERTY
As between you and the Licensor, the Licensor exclusively owns and retains all right, title, and interest in and to the Software, including its original source code and object code, implementation, architecture, selection and arrangement, digital signal processing implementation, user interface, graphics, animations, sounds, factory presets, documentation, trade dress, and all modifications, updates, and derivative works created by or for the Licensor.
The Software is protected by the copyright laws of Japan, international copyright treaties, and other applicable intellectual-property laws. The Expetri name, logos, and distinctive product appearance are trademarks and/or trade dress of the Licensor, whether registered or unregistered. This Agreement grants no right to use them except as necessary to identify and use a lawfully licensed copy of the Software.
Copyright (c) 2026 Expetri. All rights reserved.
- 4. RESTRICTIONS
Except to the limited extent expressly permitted by this Agreement or by applicable law that cannot validly be restricted by contract, you must not, and must not enable or assist another person to:
(a) copy the Software other than the installations and archival copy allowed under Section 2;
(b) sell, resell, rent, lease, lend, sublicense, assign, distribute, publish, upload, transmit, share, or otherwise make the Software available to any other person;
(c) use the Software on behalf of another person, as a service bureau, as a hosted or shared service, or in any system that permits use by anyone other than the Authorized User;
(d) modify, adapt, translate, port, merge, or create derivative works of the Software;
(e) reverse engineer, decompile, disassemble, decode, decrypt, extract, inspect, or otherwise attempt to discover or reconstruct the source code, underlying implementation, data structures, non-public interfaces, or internal operation of the Software;
(f) bypass, disable, defeat, tamper with, or circumvent any license control, signature, technical protection measure, usage limit, or security feature;
(g) remove, obscure, alter, or falsify any copyright, trademark, attribution, license, serial number, ownership, or other proprietary notice;
(h) separate, extract, reuse, redistribute, or commercially exploit any graphic, animation, sound, preset, documentation, or other asset supplied as part of the Software except through ordinary use of the Software;
(i) use the Software, or any extracted code, asset, preset, documentation, or non-public information from it, as training data or input for developing, training, fine-tuning, evaluating, or improving a machine-learning or artificial-intelligence system; or
(j) use the Software or information obtained from prohibited analysis of the Software to create, assist, or distribute an infringing or unauthorized copy, adaptation, substitute, or derivative product.
Nothing in this Section prohibits an act that applicable mandatory law expressly permits notwithstanding a contractual restriction. Any information obtained through such a permitted act may be used only for the purpose for which the law permits that act and may not be disclosed or used to infringe the rights of the Licensor or any third party.
- 5. MUSICAL WORKS, AUDIO OUTPUT, AND USER PRESETS
This Agreement does not claim ownership of your original musical works, performances, recordings, or other original content merely because you create or process them using the Software. Subject to any third-party rights in your materials, you may use audio output lawfully generated through normal use of the Software for personal or commercial purposes.
You retain your rights in original parameter settings and presets that you create. This does not grant you any right in the Software, factory content, user-interface assets, or other Licensor material incorporated in or used to produce those settings or presets. You must not distribute a preset or other file if it contains extracted Software code or protected assets.
- 6. THIRD-PARTY SOFTWARE
The Software contains third-party components, including open-source software. For details regarding the licenses applicable to each component, please refer to "Third-Party Licenses.txt" included with the installer archive.
Those third-party materials are governed by their respective license terms. If a third-party license expressly grants rights that conflict with a restriction in this Agreement, that third-party license controls solely with respect to the applicable third-party material. No third-party license expands your rights in the Licensor's original Software.

- 7. UPDATES, COMPATIBILITY, AND SUPPORT
The Licensor may, but is not obligated to, provide updates, upgrades, fixes, new features, compatibility changes, documentation, or support. Unless the Licensor supplies different terms with an update, this Agreement governs that update. An update may replace or modify a previous version and may require you to stop using the previous version.
The Licensor does not guarantee continued compatibility with any operating system, hardware, plug-in host, digital audio workstation, third-party software, file format, or service, or that any particular feature will remain available indefinitely.
- 8. LICENSE COMPLIANCE
You are responsible for maintaining the three-device limit and preventing unauthorized access to your copies of the Software. If the Licensor reasonably requests information necessary to investigate a specific suspected material breach of this Agreement, you must provide reasonable cooperation to the extent permitted by applicable law. This Section does not authorize the Licensor to access your device or collect personal data without a separate lawful basis.
- 9. TERM AND TERMINATION
This Agreement begins when you first accept, install, copy, or use the Software and continues until terminated.
Your license terminates automatically if you materially breach this Agreement and fail to cure a curable breach within fourteen days after receiving notice from the Licensor. No cure period is required for intentional unauthorized distribution, deliberate circumvention of technical protection measures, or willful infringement or misappropriation of the Licensor's intellectual property.
Upon termination, you must immediately stop using the Software and permanently delete or destroy every copy in your possession or control, including all installations and archival copies. Termination does not affect accrued rights or remedies. Sections 3 through 6 and 9 through 17 survive termination to the extent necessary to give them effect.
- 10. INJUNCTIVE AND OTHER RELIEF
You acknowledge that unauthorized copying, disclosure, distribution, circumvention, or use of the Software may cause harm for which monetary damages alone may be inadequate. To the extent permitted by law, the Licensor may seek an injunction, preservation order, or other equitable or provisional relief to prevent or stop an actual or threatened breach, in addition to any other rights and remedies available under law. Nothing in this Section limits any procedural protection or requirement imposed by applicable law.
- 11. DISCLAIMER OF WARRANTIES
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS. THE LICENSOR DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AND RESULTS. THE LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE, SECURE, UNINTERRUPTED, COMPATIBLE WITH EVERY SYSTEM, OR SUITABLE FOR SAFETY-CRITICAL OR MISSION-CRITICAL USE.
Some warranties or statutory rights cannot be excluded. In that case, this Section applies only to the maximum extent permitted by law and does not exclude those mandatory rights.
- 12. LIMITATION OF LIABILITY
Nothing in this Agreement excludes or limits liability that cannot lawfully be excluded or limited, including liability arising from the Licensor's willful misconduct or gross negligence where such liability may not be limited under applicable law.
Subject to the preceding paragraph, the Licensor is liable only for direct and ordinary damages actually and reasonably incurred as a result of the Licensor's breach. To the maximum extent permitted by law, the Licensor is not liable for indirect, incidental, special, exemplary, punitive, or consequential damages; loss of profits, revenue, business, opportunity, goodwill, or data; business interruption; or the cost of substitute products or services, even if advised that such damages were possible.
For loss caused by the Licensor's ordinary negligence, the Licensor's total aggregate liability arising out of or relating to the Software or this Agreement will not exceed the amount you actually paid to the Licensor for the license giving rise to the claim. If applicable law does not permit that cap, the cap will be the lowest amount permitted by that law.
Where the Consumer Contract Act of Japan or another mandatory consumer law applies, no disclaimer, exclusion, or limitation in this Agreement will apply to the extent that it would be invalid under that law.
- 13. LICENSEE RESPONSIBILITY AND THIRD-PARTY CLAIMS
You are responsible for your use of the Software and for ensuring that the audio, data, and other materials you process or distribute do not violate law or third-party rights. To the extent permitted by applicable law, you will indemnify the Licensor against a third-party claim, damage, or reasonable cost to the extent directly caused by your intentional unlawful distribution of the Software, willful infringement of the Licensor's rights, or fraudulent use of the Software. This obligation does not apply to the extent the claim was caused by the Licensor.
- 14. EXPORT AND LAWFUL USE
You must comply with applicable export-control, sanctions, and trade laws and must not use or distribute the Software in violation of applicable law.
- 15. GOVERNING LAW AND JURISDICTION
This Agreement is governed by the laws of Japan, without regard to conflict-of-law principles. To the extent permitted by applicable law, the Tokyo District Court will have exclusive jurisdiction as the court of first instance over any dispute arising out of or relating to this Agreement or the Software.
Nothing in this Section deprives a consumer of the protection of mandatory law or a mandatory forum that cannot validly be waived by agreement.
- 16. CHANGES TO THIS AGREEMENT
The Licensor may apply a new agreement to a future paid upgrade or other new release by presenting it for your acceptance before installation or use. A new agreement does not retroactively govern a version you already licensed unless you separately agree or the change is validly made under the rules governing standard terms in the Civil Code of Japan.
Where the Licensor changes this Agreement without obtaining individual consent, the change will be made only when it benefits users generally or is reasonable in light of the purpose of the Agreement and the circumstances specified by applicable law. The Licensor will announce the content and effective date of such a change in advance by a reasonable method.
- 17. GENERAL TERMS
This Agreement, the applicable purchase terms, and the third-party licenses constitute the entire agreement concerning your license to the Software and supersede prior or contemporaneous statements on that subject. A purchase order or other Licensee document does not modify this Agreement unless the Licensor expressly agrees in writing.
If any provision is held invalid or unenforceable, it will be enforced to the maximum extent permitted and the remaining provisions will remain in effect. Failure to enforce a provision is not a waiver. A waiver must be express and in writing.
You may not assign or transfer this Agreement or your license without the Licensor's prior written consent, except where applicable mandatory law gives you a non-waivable right to do so. The Licensor may assign this Agreement in connection with a transfer of the Software, the related intellectual property, or the Licensor's business, provided that the assignment does not materially reduce your rights.
Headings are for convenience only. "Including" means "including without limitation." The English-language version of this Agreement controls over any translation to the extent permitted by applicable law.
