Well, I suspected the reason like this, and I agreed. On the other hand, if VVV supposed to be vintage-like reverb, it is logical that it would use similar approach for estimating size like vintage reverbs it inspired by, at least for easier programming the classic patches.
And we all know that algorithmic reverbs all are shit if speaking of faithful modelling of real spaces, in the best cases the result is the approximation only (very often such approximation is more pleasant than real room) but we agreed to this approximation, so it is possible to agreed with the fake size control. Just for easier programming the classic patches.
Changing the Size control to meters, besides continuing to propagate a lie
, would also break all of the existing presets and projects that use ValhallaVintageVerb. So that ain't gonna happen. In general, changing parameter ranges in a plugin is a bad idea once that plugin has been released.
It is worth emphasizing that ValhallaVintageVerb isn't a direct clone of any pre-existing reverb - it is "inspired by" the old reverbs. I changed a lot of things, in order to have a reverb that is easy to use. If I wanted an exact recreation of an older reverb, I would have used a 3D "realistic" GUI, as opposed to a 2D GUI that looks like the paint job on a 1975 Winnebago. I made all sorts of changes to the algorithms and parameters, to simplify the interface and get the sound to where I wanted it to be.
EDIT: The older Lexicons also had a very loose relationship between the parameter values and the behavior of the algorithm. A RTMid time of 2.00 seconds on a 480L, for example, may end up decaying at a rate far different than the scientific definition of RT60, which is how long it takes for the signal to decay to 1/1000th of the initial decay amplitude. The reverb decay rate might also change with the Size setting, such that a 2 second RTMid at a small value of Size might have a far different RT60 than a 2 second RTMid setting at a large value of Size. The filter frequencies didn't necessarily correspond to the display values, either.
I know that Martin Lind worked hard on matching the actual 480L settings in his LX480 plugin. I took the approach of calculating a technically "correct" RT60 (and my guess is that Michael Carnes has taken a similar approach in his plugins).
And all these L-like reverbs challenges - there are some difficulties setting up all reverbs to the similar sounding patches, also with VVV Size control.
ValhallaVintageVerb wasn't designed to compete against other reverbs in a Lexicon sound alike challenge. It was designed to be used by musicians and engineers to make music.
If people want to have plugin shootouts, fine by me, but I'm not changing the VeeThree parameters in order to make things closer to another plugin. I trust that the people creating the tests will use their ears to dial the settings in. The different plugins out there have different approaches to calculating parameters, and dialing things in by ear will be a better way of matching things than relying on the displayed parameter values.
