Terms and Conditions and Licence Terms

§ 1 Provider and scope

The provider of the software “4seasons” is Louis Yung, Mittelseestraße 2, 63065 Offenbach am Main, Germany, info@wavtherapy.com (“we”). These terms govern the supply and use of the software.

The contract of sale is concluded through our distribution partner Lemon Squeezy, who act as the seller (merchant of record). Their terms govern payment, invoicing and VAT. The licence terms below govern the software itself.

§ 2 What is supplied

4seasons is an instrument plugin, supplied for macOS in VST3 and Audio Unit format and as a standalone application, and for Windows in VST3 format, including the sound library supplied with it and the factory presets. The system requirements are stated on the product page.

Updates within major version 1 are provided free of charge — this corresponds to the statement “Free updates within version 1” on the product page. Beyond that there is no claim to future features or to subsequent versions.

§ 3 Activation

The software is supplied with a licence key and has to be activated online once. After that it can be used permanently without an internet connection. The key may be active on up to two devices at the same time; activations can be released again from within the software.

§ 4 Licence — what you may do with the sounds

Permitted

• Using the software and all sounds supplied with it in your own music productions, including commercial releases — with no further licence fees, no revenue share and no credit required.
• Using them in commissioned work, in film, advertising, games and library music.
• Using them yourself on up to two of your own devices (see § 3).
• Creating your own presets and passing them on, provided they contain no audio files from the library.

Not permitted

• Passing on, reselling or publishing the software, the sound library or individual audio files — including in altered form.
• Using the sounds as part of another sample pack, preset pack or instrument, that is, anywhere the sound itself is the product being sold rather than part of a music production.
• Passing on the licence key.
• Circumventing activation, and reverse engineering the software, except where the law mandatorily permits it.

The rule of thumb: Make as much music with it as you like. Do not resell the sounds themselves.

§ 5 Rights in the sounds

All sounds were created by us. The rights in the software and the library remain with us; you receive a non-exclusive, perpetual and non-transferable right of use to the extent set out in § 4.

We acquire no rights whatsoever in the musical works you create with the software.

§ 6 Warranty

The statutory warranty rights apply. We do not warrant that the software runs without fault in every combination of hardware, operating system and host application. Please check the system requirements before buying.

§ 7 Liability

We are liable without limitation for intent and gross negligence, and for injury to life, body or health. In the case of ordinary negligence we are liable only for breach of a material contractual obligation, and limited to the foreseeable damage typical for this kind of contract. Otherwise liability is excluded. Liability under the German Product Liability Act (Produkthaftungsgesetz) remains unaffected.

§ 8 Right of withdrawal

Consumers have a right of withdrawal. The details are set out in the right of withdrawal notice. The full 14-day period applies: the checkout does not ask for the express consent that would be required for the right to expire early for digital content.

§ 9 Final provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. As against consumers, this choice of law applies only to the extent that it does not deprive them of the protection of mandatory provisions of the state of their habitual residence. Should any provision be invalid, the validity of the remainder is unaffected.
