Software licence agreement

Last updated: September 2026

This Software Licence Agreement ("Agreement") is between Photon Consulting Limited, trading as SquareWave Studio ("Licensor") and you, the end user ("Licensee"). By installing or using SquareWave Studio software, you agree to be bound by this Agreement.

Important: no warranty, and keep backups

Nothing in these terms affects your statutory rights as a consumer.

SquareWave Studio software, free and paid, is provided "as is", without warranty of any kind, express or implied. To the fullest extent permitted by law, we are not liable for any loss of or damage to data, including samples, patterns, projects, presets or the contents of your device, or for any indirect or consequential loss.

Before you use the software with your device or your files, back them up. Keeping those backups is your responsibility.

  • Create and manage content for Teenage Engineering devices, including the OP and EP series and Pocket Operators
  • Use the software for personal and professional purposes, including paid work

This licence is personal to Licensee and cannot be shared, rented, or sold.

Free apps. PO-PatchStudio, and the free features of our other apps, are licensed under this Agreement at no charge, with no licence key and no device limit. The parts about licence keys, activation, the number of devices and payment (sections 2, 3 and 7, the device documentation and excessive-use provisions of section 12, and the payment terms in our Terms of Service) apply only to paid licences.

  • Lost or forgotten licence keys can be recovered by contacting support with proof of purchase

3. Licenced number of devices

Each licence of SquareWave Studio software permits installation and use on up to5 devices owned or controlled by the Licensee.
