A lot of extra info

Here it is. By default, there is a filter at number 3. Many choose filter 2 (Slow Roll-off)
That's not my description. But it may come in handy.
1.
Sharp Roll-off - is the driest, flat and "prickly" sound. It gives a little more micro-details, but loses a lot in musicality to the rest of the filters. The vocals turn out to be too bland. The instruments are subjectively located at the same distance from the listener. It is the least pleasant to me, so I practically do not use it. But, it may well be suitable for those who like the "evil" sound if it even applies to this player and fast cymbals.
2.
Slow Roll-off (The best according to many) - is my favorite, the complete opposite of the previous one. The scene is heard up and down, a kind of 3D panorama appears. The vertical height of the instruments is quite well felt and, in general, the air between the instruments is most felt. Vocals are as close to the listener as possible, there is more volume and physicality in it. Also, of all the modes in this, the vocals are served as gently as possible, you can even say velvety, as it is not banal. The best worked out are the after-hours. The music sounds very cohesive and musical, while not slipping into the mud. Vocals, strings, and wind instruments in this mode are as juicy and pleasant as possible. The high frequencies are pushed back a little, while losing a little in detail, which in my opinion is not critical, but fans of HF may not be satisfied.
3.
Short delay Sharp Roll-off (Default) - is a cross between the first two, and in terms of frequency of use, I would put it in second place. The stage is flatter than in the previous mode, more in width than in height and depth, the vocals move backwards, the high frequencies are worked out better and go ahead. The biggest difference in vocals is that sharpness is added (in the area of sibilants), while not losing much in physicality. But this sharpness does not exceed reasonable limits, and can be useful when you want a little more drive from the vocals.
4.
Short delay Slow Roll-off - is also more like a combination of slow and short filters. According to the attenuations and the scene, about like a slow roll-off, there is depth in it, but in the high frequencies area somewhere, rather the spinal cord, there is a slight dip. Moreover, this moment is difficult to describe, the high frequencies are not that failed, they are there, but there is a feeling of some kind of unnaturalness, which sometimes causes dissonance, and because of this, something also begins to be missing in the vocal delivery.
5.
Super Slow Roll-off - is a very specific filter. All that has been said about slow roll-off can be safely multiplied by two. But as the Poles say, "what's wrong is not healthy" — therefore, together with the monumental stage and powerful vocals, an even greater loss of details is added here, a much more stringy sound, with an influx of instruments on each other, and this is already too much, as for me. In general, this filter is definitely contraindicated for fast styles, but a variety of ambient, psychill and the like come on it very well.
6.
Low dispertion - !?!?!... Little info. Note the extended frequency response of this one up above? The impulse looks like it’s a compromise between Sharp Roll-off (sometimes called Linear Phase) and Short delay Sharp Roll-off, with less pre-ripple and more post.
