I know this is probably something simple but I just can't seem to understand how to adjust envelope settings.
For example, say I want to add a hi-pass filter. There are db settings on the left, frequencies on the right, and impulse time across the bottom. If I wanted attenuate frequencies below 200 Hz -20 db, would I set the right node at 200 Hz and the left node at -20? Does the far right node always denote the frequency of the hi-pass and the far left node the amount of attenuation? What do added nodes between the two represent? If I added a node say at 0.450 seconds, -40, 1.4 kHz, what is really happening here? Does the time domain across the bottom come into play? Do all nodes represent all 3 parameters?
A lot of questions I know, but there must be something obvious I'm overlooking. On all these filters I just can seem to grasp how a linear, 2 dimensional line is applied across 3 parameters.
If someone could offer a simple explanation I would appreciate it very much.

Hi-Pass and Low-pass filter envelopes allow you to make sweeps. For simple EQing please use Equalizer envelope.

Thanks for your response Aleksey. Yes, the EQ is pretty straight-forward. But with your other filters the use of a 2 dimensional line adjusted against 3 parameters continues to confuse me. I know it's probably a simple perceptual thing I'm not getting. I do wish you had some detailed instructions as to how to use these filters.

Low-pass and high-pass envelopes allow you to create sweeping filters - whose corner frequency changes over duration of the impulse response. There is nothing hard in this concept.

A simple explanation via an example would have been very helpful. Whether you think there is nothing hard in it or not is not the point.
I own 18 of your products Aleksey. I'll certainly recall your intellectual superiority the next time I consider purchasing anything.

A simple example would be time-varying high-frequency damping. So, you open the Low-pass envelope and put its starting point to 20kHz (full spectrum open) and its ending point to 16 Hz (fully damped spectrum). This will produce a reverb with damped higher frequencies with damping varying over time.
(I'm not trying to show I have any intellectual superiority)
