Viper licence agreement
Last updated October 2026
This is an agreement between you and eXetacy Audio about Viper. By installing or using Viper, you agree to it.
Your licence
Whatever you pay for Viper, including nothing, you get a personal, non-exclusive, non-transferable licence to install and use it on computers you own or control.
Your music is yours
Use Viper on any music for any purpose, including commercial releases, beats, sync, streams and live shows. You owe no royalties and no credit, though a shout-out is always appreciated.
What you can't do
Don't share, resell, rent or upload Viper, its installers or its factory presets. Don't remove copyright notices, and don't reverse-engineer, decompile or modify Viper, except where the law allows it.
Ownership
Viper's code, design, sounds and presets, and the eXetacy name and logos, belong to eXetacy Audio. This licence lets you use Viper; it doesn't transfer ownership.
Updates
Updates to Viper are covered by this agreement unless they come with new terms.
No warranty
Viper is provided "as is". We work hard to make it stable, but we can't promise it will work with every computer, DAW or setup. Save and back up your projects.
Liability
As far as the law allows, eXetacy Audio isn't liable for indirect or consequential losses, including lost projects or data, and our total liability is limited to what you paid for Viper.
Ending the licence
If you break these terms, your licence ends and you must delete Viper.
