FAQ
Common support questions
When is QuEQ available?
QuEQ is coming August 2nd. Store, account, download, trial, installer, and activation details will be available before sales begin.
How long is the QuEQ trial?
QuEQ trial mode is planned for 28 days. Trial state is separate from audio settings, so licensing reminders do not rewrite saved project parameters or change the current sound.
Where do I find downloads and licenses?
Use the Q profile menu to sign in with your account email and password, then open Downloads or Profile. Installer access is tied to an active purchase or trial.
How does offline activation work?
The plugin creates an activation request on the offline computer. Upload that request from a connected device in Profile, download the signed license file, then place it in the QuosineDSP license location used by the plugin formats.
What should I include in a product issue report?
Include the product, host app, operating system, plugin version, a clear description, what you expected, what actually happened, and screenshots if they help show the problem.
Can I ask general production questions?
Yes. For product-specific help use support. For learning material, use the Learn section for EQ concepts, phase behavior, stereo work, and QuEQ control guidance.
