      @Harry I think this "modulation" along the brush path of some distortion parameter is an interesting idea.
      I added this to the backlog. Some details need to be worked out (ideas are welcome), but I think this could be implemented before version 2 (if not version 1.2).

      Glad to read that!

        This will be hard to do with vectors only.

          I know, but results may be surprisingly good!

          Krita have some more options for modifiers/modulators i.e. stylus rotation and tilting.
          They call it sensors. Here is some more info:

          Maybe for future development?

            I don't think Harry meant that VS should strive to imitate natural media brushes
            accurately like Rebelle does — it's just the random, organic part of the natural
            brushes that are to be imitated in vectors.

            As I suggested, picking random brush contours from a "contour table" (similar to
            wavetables in synths) is one way to achieve this. It's basically stringing them
            together (with the first and last connecting nodes free to move vertically) and
            bending them along the brush spine, then maybe overlapping three brushes
            with different opacities would get you respectably close to the organic quality
            of bitmap brushes.

              @Subpath I downloaded Alchemy but it's so old that it doesn't work on my Mac.

                Another way would be to have just one brush contour but don't stretch it — instead repeat it but randomize the nodes.
                Maybe this approach would be faster for "live" drawing.

                  that, sad to hear, because its a nice little Tool
                  as i wrote works here on Win 10 without any Problem
                  despite that it is from 2010

                  i will create a video to show some Tools of it
                  but this will take yet some time

                    you could try "Webchemy" its a online drawing tool
                    in the style of Alchemy, but have much fewer tools.

                          I found temporary workaround also in the Stroke Width panel's menu - there is "Randomize profile" option. Still it's "post production", not "live" and not exactly what I meant:

                            @Harry If there are some good inspirations on how such a brush should look like, please upload here or send them to me by email.

                              Problem is, that I don't know.

                              Let's say I'd like to design some abstract pattern. I would take "Live random effect brush tool", and I would experiment and look for some inspiration from great and interesting shapes this kind of brush could produce.

                                Hi

                                As a source for inspiration, for modulate Strokes, the painting program
                                Black Ink came to mind.

                                "Black Ink" uses a kind of controller nodes to modulate brushes
                                to set and control random strokes and has a node system for layers.

                                Here are some videos

                                Video about the Brush Controllers:

                                Scattering a Brush may also be interesting
                                her a Video about it
