(Comment on) Problems with external spectrum off

Sun, 29 Mar 2026 18:38:40 GMT

Hi Ralph, You don't need three instances to see an overlay of another track. If you have Pro-Q 3 on Bass and Kick, you can open one instance and select the other track for the external spectrum. Open the analyzer menu at the bottom bar of the plug-in. At the top right of the menu you will see SC with a small arrow. If you click the arrow you will see all other instances of Pro-Q 3, and you can select which one you want to see in the external spectrum.

Have you just updated to macOS Tahoe? There is a small issue when using Logic, but unfortunately that's on Apple/Logics side so we are unable to fix that. In Logic the area just above the plug-in name at the bottom has been made unclickable. This results in any button just above the plug-in name in our button bar becoming harder to access. There still is a small area at the top of the button that you can still click, but a large part of the button is unclickable. We've reported this to...

Hi DongHyeon, It's best to send us an email for that, so we can disclose what computer will be deactivated without posting this on our public forum.

Ive been in Abelton for years using EQ eight and three , I want to use FFQ3. I have the license and was looking thru videos. My work flow is simple as I wanted to use instances of the plug in on certain channels like Kik, Bass and a few mid range frequency instruments. I was looking at a tute and according to that if I want to fix the clash between my kk and bass would have to have THREE instances of Q3, one on the kik another on the bass and another on the master. I did all of this but...

Thank you for your answer. I uninstalled and reinstalled ListenHub and Pro-Q4 both, and after that, I was able to run Pro-Q4 (4.11) in ListenHub. I have no idea what on earth caused the error before, but anyway, it is resolved now.

(Comment on) Pro Q 4 keep asking for license key

I see you purchased an upgrade license from one of our resellers. For an upgrade license to work, you also need a valid license for its base product. So if you have an upgrade license for Pro-Q 3 you would need a license for Pro-Q 2 or Pro-Q 1. Without a license for its base products the upgrade license will not work. Since you have purchased the license through a reseller, unfortunately I cannot help you with that. I suggest getting in touch with your reseller to see if they can swap...

Restarting ListenHub rescans it. In other words, if you restart ListenHub, the Fabfilter folder and the Pro-Q4 plugin reappear in the FX list. However, when I try to load Pro-Q4 into the ListenHub FX-Chain, there is no response and it disappears again. ListenHub is essential for my audio monitoring system because it allows me to run AU plugins on system audio. However, I am very perplexed that my favorite Pro-Q4 can no longer be used in ListenHub after updating to version 4.11. And...
