Demo mode and your license

Demo mode

Until you enter a license key, PianoFlex runs in demo mode. Demo mode is the full program, with three differences:

• Each session lasts 20 minutes. A session starts when you start PianoFlex, or when your music program loads the plugin. After 20 minutes the sound fades out, and the yellow line tells you the session is over. In your music program, the plugin is then silent, also when you export. Start PianoFlex again, or load the plugin again, for another 20 minutes. Demo mode never expires, so you can try PianoFlex for as long as you like.
• Render to audio and Record are grayed out. They're part of the full version.
• "(Demo)" appears after PianoFlex's name at the top of the window, with the minutes you have left and two buttons: Buy…, which opens our website, and Enter license key…, which opens the license box.

Everything else works in demo mode: every preset and slider, layers, Compare, and saving your own presets. So any presets you make while trying PianoFlex are still there after you buy.

Entering your license key

After you buy PianoFlex, you'll get an email with your license key.

1. Click Enter license key… at the top of the window. (It's also in the About box.)
2. Type the email address you used when you bought PianoFlex.
3. Copy the license key from your purchase email, then click Paste.
4. Click Unlock.

The license box closes, and the yellow line tells you who PianoFlex is licensed to. The About box shows this too.

• You only need to enter the key once. It's kept for your Windows user account, and it unlocks both the PianoFlex program and the plugin.
• If you bought a key for both programs, the same key also unlocks ComposerFlex.
• There's no account to create and no online activation. PianoFlex never connects to the internet. You may use your license on all of your own computers.
• On a new PC, enter the key again. Or copy the file license.txt from your old PC to the same place on the new one. To find it, type %APPDATA% in File Explorer's address bar and press Enter, then open the Flex Music Labs folder.

If your key isn't accepted

The license box tells you why:

• "This key does not match this email address": use the email address and the key exactly as they appear in your purchase email. Pasting the key, rather than typing it, avoids mistakes.
• "Enter the email address you used to buy" or "Paste the license key from your purchase email": one of the two boxes is empty.
• "This key is for ComposerFlex, not PianoFlex": you've entered your ComposerFlex key. Enter it in ComposerFlex instead.
• "This key is not for PianoFlex" or "This key is not for this version of PianoFlex": check that it's the key from your PianoFlex purchase email.
• "The key is right, but it could not be saved": Windows didn't let PianoFlex save the key. The rest of the message says why.

If it still won't unlock, write to [email protected] and include your purchase email. License-key problems always get a reply.
