End User Licence Agreement
Lexter 91 · last updated 4 November 2026
This agreement is between you and ZAZY s.r.o. (“we”). By installing or using Lexter 91, you agree to its terms.
1. Who we are
ZAZY s.r.o., V Chaloupkách 82, 252 31 Všenory, Czech Republic · Company ID (IČO) 093 80 663 · VAT ID CZ09380663 · Registered with the Municipal Court in Prague, file C 334594. Contact: [email protected].
2. The software
“Lexter 91” means the Lexter 91 application for macOS, the Lexter 91 plug-ins (AU, VST3, AAX), the data built into them, including the device map and the impulse responses used by Preview, and the documentation.
3. Licence
When you buy a licence, we grant you a personal, non-exclusive, non-transferable and perpetual licence to use Lexter 91 for one user on up to two Macs that you own or control. You activate it with your licence key and the e-mail address you used for your order. To move the licence to another Mac, deactivate it in Lexter 91 › License… on the old Mac first.
The licence covers Lexter 91 and its updates. It does not include other products.
4. Trial
Without a licence, Lexter 91 runs as a trial. For 90 days from the first launch of the app or a plug-in on a Mac, it is the full version. After that it keeps running but saves nothing: no files, no Store to the unit and no plug-in state in DAW projects, until you activate a licence. Files you saved earlier can still be opened.
5. Updates
Updates to Lexter 91 are free for licence holders. We decide what an update contains and when it is published.
6. Built-in data
The device map and the impulse responses inside Lexter 91 were measured and created by us. They are licensed for use inside Lexter 91 only. You may not extract, copy, convert, sell or redistribute them, or use them in other software, sample libraries or impulse response collections.
7. Restrictions
You may not rent, lend, resell or share Lexter 91 or your licence key, and you may not reverse engineer, decompile or disassemble it, except where the law allows this regardless of this agreement.
8. Hardware and compatibility
Lexter 91 is an editor for the Lexicon PCM 91 hardware unit and needs the unit, a two-way MIDI connection and a Mac with macOS 14 or later. We test it on our own equipment but cannot test every combination of Mac, macOS version, MIDI interface and unit. Please use the trial to check that it works on your setup before you buy.
9. Trademarks and independence
Lexicon and PCM 91 are trademarks of their respective owner. Lexter 91 is an independent product, not affiliated with or endorsed by Lexicon or Harman.
The names Lexicon and PCM 91 are used only to identify the hardware that Lexter 91 works with. Lexter 91 contains no software, firmware or code of Lexicon or Harman.
10. Purchase and refunds
Lexter 91 is sold by Lemon Squeezy as our reseller and Merchant of Record. Lemon Squeezy processes the payment, charges VAT and sends the receipt under its own buyer terms. You can ask for a refund within 30 days of purchase (see the refund policy). When a purchase is refunded, its licence key is disabled.
11. No warranty
Lexter 91 is provided “as is”. To the extent permitted by law, we give no warranty that it is free of errors or fit for a particular purpose. Your statutory rights as a consumer are not affected.
12. Limitation of liability
To the extent permitted by law, we are not liable for indirect or consequential damage, loss of data or loss of profit arising from the use of Lexter 91. Our total liability is limited to the price you paid for the licence. This does not limit liability that cannot be limited by law.
13. End of the licence
The licence ends if you break this agreement or if your purchase is refunded. You must then stop using the licensed version.
14. Governing law
This agreement is governed by the laws of the Czech Republic. Mandatory consumer protection rules of the country where you live remain unaffected.
