FabFilter Pro-Q2 vs Pro-Q3 vs Pro-Q4
Hi!
Will older versions of FabFilter Pro-Q remain usable, even after they have reached the end of support? I personally prefer the older interfaces in design and simplicity but am considering using newer versions in parallel.
Pro-Q2: I use it all the time
Pro-Q3: I rarely use it
Pro-Q4: I plan to use the Instance List but am worried that the automatic analysis feature will require more software upgrades (which would invalidate older software that I appreciate more than getting a new equalizer!)
/(T_T')\
Should I just stay on the old stuff and not worry?

Hi Wickerse,
We don't have any plans to discontinue Pro-Q 3 or Pro-Q 2. We know how widely they have been used, and that they are still being used.
For a future perspective though, we think it's better to use the latest version. There's a new interface you need to get used to, but if we may believe our customers this goes really fast. All the features of the old versions are in there, and in case you need them some extra as well.
In regards to the instance list, there's not particularly more or less updates for that than for another version. There might be an extra update when we for instance add more plug-ins to the instance list, but in terms of general updates for OS support they will be the same as any other plug-in.
