Once you have downloaded and installed the evaluation copy of the FabFilter Twin, you may use it freely for 30 days. Every time you start the plugin, you will see the following dialog:
While there are still days left, you can click Evaluate to start working with the synthesizer. If you want to keep using FabFilter Twin after the evaluation period, you must buy a copy in the online FabFilter Shop by clicking the Buy Now button in the evaluation dialog.
We accept major credit cards, check payments, wire payments, and even PayPal. Your credit card number is safe because the FabFilter Shop uses secure connections and strong encryption.
Immediately after you have purchased your copy, you will receive an e-mail containing your personal license key. You use this license key to turn the evaluation copy into a fully registered version without the evaluation dialog and the 30-day trial restriction.
