GammaDelay
How do I download, install, and activate the plug-ins?
- Download the installer only from the official PhotonDSP website or from the purchase e-mail link.
- Close your DAW, install the plug-in, and refresh or rescan its VST3 list.
- When you open the plug-in for the first time, the activation window appears. Enter your serial number first, then click Activate.
If a trial is already running, use the Activate button at the bottom of the plug-in interface to reopen this window.
Are the plug-ins compatible with my operating system and DAW?
The plug-ins run on Windows 10/11 x64 in 64-bit DAWs that support VST® 3. Windows on ARM, 32-bit operating systems, and 32-bit DAWs are not supported. Exact requirements are listed on each product page.
Which formats are supported: VST3, AU, AAX, 32-bit, or 64-bit?
Currently, only 64-bit VST3 for Windows x64 is available. AU, AAX, 32-bit, macOS, and Linux are not currently supported, but support is planned.
What should I do if activation fails or the plug-in remains in Demo/Trial Mode?
- Check the serial number. It must match the selected product and contain no extra characters.
- Check your internet connection, Windows date and time, VPN, proxy, and firewall settings.
- If you requested a trial, confirm the link in the e-mail, return to the plug-in, and click Refresh.
- Restart the DAW. If the problem remains, send support the exact error message and the Request ID, if one is displayed.
How many computers can I use one licence on?
One licence permits three active installations on devices owned by the licence holder. Sharing the key with third parties is not permitted, although multiple users may use the plug-in on the same device.
Can I activate or use the plug-ins without an internet connection?
Licensed plug-ins do not require an internet connection during use. Internet access is required for the initial activation and to complete a product refund.
Trial versions require an internet connection both for activation and continued use.
How do I uninstall or completely reinstall a plug-in?
Close every DAW and remove the corresponding VST3:
C:\Program Files\Common Files\VST3\PhotonDSP\PhotonDSP GammaDelay.vst3C:\Program Files\Common Files\VST3\PhotonDSP\PhotonDSP WideEngine.vst3
For a normal reinstall, do not delete %LOCALAPPDATA%\PhotonDSP\; activation data is stored there. For a complete settings reset, first back up and then delete the relevant product’s preset folder under %APPDATA%\PhotonDSP\.
How do I contact support, and what information should I include?
Use the support form on this website and include:
- the product and version shown in its About window;
- the exact Windows and DAW versions;
- the error message and the steps that cause it;
- a screenshot, log, and Request ID, if available;
- the purchase e-mail and FastSpring order number for licence-related questions.
The form accepts up to eight permitted files with a combined size of up to 15 MB.
How do I register a serial number or code received from a reseller?
FastSpring processes PhotonDSP payments as the Merchant of Record. A FastSpring order number or receipt is not a plug-in serial number. After the required verification, PhotonDSP shows the serial number on its confirmation page and sends the same serial number to the verified purchase e-mail. Enter that PhotonDSP serial number in the plug-in activation window.
The plug-in is installed but does not appear in my DAW. How do I find or rescan it?
- Check that the plug-in exists in
C:\Program Files\Common Files\VST3\PhotonDSP\. - Restart the DAW and perform a full VST3 scan. Follow the instructions for your specific DAW.
- Search for the manufacturer PhotonDSP and check the DAW’s blacklist or blocked plug-ins list.
- Remove older duplicates of the same plug-in from other VST3 folders, then scan again.
Where are the plug-in files installed, and can I change the installation folder?
The standard folder is C:\Program Files\Common Files\VST3\PhotonDSP\. Moving VST3 files manually or choosing a non-standard folder is not recommended: your DAW may not scan it, and duplicate files may cause version-detection problems.
How do I move an activation to a new computer or deactivate the old one?
Install the plug-in on the new computer and activate it if a slot is available. Deleting the VST3 or local files does not release a server activation slot. Contact support to reset a slot for an old device that is no longer accessible.
Reinstalling Windows creates a new local identity and may also require the previous slot to be released.
Why does my purchased product, licence, or serial number not appear in an account?
PhotonDSP does not currently use a separate customer account. FastSpring stores the payment and order record, while PhotonDSP shows the serial number on its confirmation page and sends it to the verified purchase e-mail. Store it securely: the complete serial number cannot be recovered from the server database.
If the e-mail does not arrive, check your Spam folder and contact support immediately with the purchase e-mail and FastSpring order number.
Where can I download updates, previous versions, or legacy installers?
Download current versions only from the official PhotonDSP website or through an official customer download link. Support can provide a previous version only if it remains available in the archive, so keep your own copy of any installer you rely on.
Do not install old and new copies of the same VST3 at the same time.
Does the plug-in work on new versions of Windows, macOS, and Apple Silicon computers?
Only the Windows x64 versions explicitly listed on each product page are supported. Windows on ARM, macOS, and Apple Silicon are not currently supported. Compatibility with a new operating system or DAW is considered confirmed only after official testing.
How do I change my e-mail, restore access, or merge multiple accounts?
PhotonDSP does not currently use separate customer accounts. To change a PhotonDSP customer e-mail or merge customer records, contact PhotonDSP support, provide the old and new addresses, and verify ownership with the FastSpring order number. Changes to FastSpring payment or receipt details may require FastSpring account management or FastSpring support and do not automatically merge PhotonDSP records.
Is there a free trial, and what are its limitations?
Yes. Each product has a 14-day trial that requires e-mail confirmation and an internet connection. If the online permission is not renewed, processing is suspended and the plug-in passes the unprocessed signal through.
Where are presets stored, and what should I do if they disappear?
User presets are stored here:
- GammaDelay:
%APPDATA%\PhotonDSP\GammaDelay\Presets\PresetsTable.txt - WideEngine:
%APPDATA%\PhotonDSP\WideEngine\Presets\WideEnginePresets.txt
Close the DAW and restore the file from a backup. Factory presets can be restored by reinstalling the current version of the plug-in.
Can I transfer, import, or save my own presets?
Yes. Save presets using the plug-in’s own controls. To transfer them, close the DAW and copy the preset file from the corresponding product folder. Before replacing the file on the new computer, save a backup copy of it.
GammaDelay and WideEngine presets are not compatible with each other.
Will old projects open correctly after a plug-in update?
Updates are designed to preserve the plug-in identifier, parameters, and saved project state. Before updating, still save the project, user presets, and current installer, then verify a copy of the project after the update.
Do not keep old and new copies of the same VST3 in different folders at the same time.
How do I request a refund?
Contact PhotonDSP support to request a refund. Support will initiate the return process. Then connect every computer on which the affected plug-in is activated to the internet, launch the plug-in, and wait until its activation is reset.
Once support confirms the required resets and refund eligibility, it can initiate the payment refund through FastSpring, PhotonDSP’s Merchant of Record. FastSpring processes the financial refund; it is not automatic.
