What do the 4 modulators do in MAutoDynamicEQ?

Do you mean the morphing feature?

>but leaves me wondering why oh why?
 
I suspect simply because it was just dead easy to add.  Vojtech, I must believe, is a master of C++ class design.  I appears that he's accumulated this powerful collection of classes like a multi-purpose modulator.  Classes are like cookie cutters that produce cookie objects.  Once you've got one that works, it's no work at all to produce lots of cookies.  Who needs modulation in an EQ, [auto]dynamic or otherwise?  Probably next to nobody - at least I'm hard pressed to think of a common use of EQ modulation.  If there were, you can assume we'd see such in Pro-Q at very least, given how much FabFilter likes modulation with finesse.
 
But putting a Melda modulator in the EQ doesn't hurt anything efficiency-wise and it probably costs Vojtech next to nothing in extra development time, so why not?  At least that's what I would assume here.

I was unaware there were modulators in that plugin, and I thought I'd dug into every conceivable aspect of it. Can you point me to the text quoted above, either in the help file or in the product page?
 
The only thing I can think of is that it might be referring to the X/Y controller, which allows you to automate morphing from one configuration to another. But that wouldn't explain the reference to an ADSR envelope. It almost sounds as though the text was inadvertently pasted from another product.

I haven't used them, but I think the modulators could be used to modulate the frequency, gain, ect...
 
It says they can modulate any parameter.
 
IOW you could use one modulator to change the freq while another modulator modulates that to a certain pulse.
 
And the modulators can be affected by the SC so bass drum into the SC and have the modulator affect a fequency + or - depending what you want.

You can make a Wah Wah effect with your EQ.

Well that was some of the first things I thought of. I'm sure with a little imagination it could go somewhere.
 
But you have to be willing!! : )

It all stems a bit from synth programming. Where many modulation sources are feeding destinations. It is in the modulation part of a synth patch that amazing amounts of detail and subtlety can be implemented.
 
That EQ is well above normal for offering those sorts of options. Even with 4 modulators it seems a lot can be done. What I find interesting is the fact an ADSR envelope can be triggered via midi and if you think about the possibilities in terms of sending that modulation source to a number of destinations within that EQ, then some pretty interesting and cool effects would be possible. Especially if you did things like make the EQ ADSR envelope match in a way the envelopes that might be within a synth patch that is also triggering that EQ modulation effect.
 
The LFO options could be used to add very smooth and subtle liquid movement to a sound or patch etc..(not WAH sorry!) Think comb filtering for example and having sweeping or moving nulls. Or two filters setup one on each side of a stereo image and you are modulating each side differently too. Perhaps in sync but different. That fact the modulators can be synced to the project tempo is also cool.
 
You don't have to use any of the modulation sources of course but the fact they are there to me makes that EQ quite attractive. Thanks Mike for bringing it up in fact. It is powerful.
