Control Brush-Nozzle sequence

[solved]

I am working on my own custom brushes. 

I am creating brushes with 5 - 8 different nozzles. The random setting in the nozzles texture  panel works quite well for some brushes but I need to control the sequence of the nozzles a little more. 

The problem is that the random setting produces a stroke where the nozzles often get repeated twice or more in a row. In my example you can see that the "square star" appears twice in a row and the "circle" 3 times in a row in a single brush stroke.

 

- Is it possible to iterate in one sequence trough all the nozzles ? In this case: 

Star -> Square Star -> Circle -> Heart -> Polygon -> Star -> Square Star -> Circle -> Heart -> Polygon and so on...

 

- Random would work too but without repeating the same nozzle twice in a row. 

For example:

Circle -> Polygon -> Circle... would be acceptable.

Circle -> Circle -> Polygon... A circle after a circle should be avoided. The random setting unfortunately generates a lot of this patterns where on brush nozzle gets repeated twice or more in a row.

If I got it right, this post is about the same question, but it is quite old and does not really provide more information on this topic.

I have no idea if or how well this would work but have you tried changing "Random" to "Cyclic"?

For some use cases it could work very well. Yes I have tried all the possible settings. 

Cyclic results in a brush stroke like this:

No, for what is this curve setting ?

I am not sure. That's why I am asking if changing it makes any difference. I would text it myself but I do not have any brushes with several different nozzles.

It looks like a standard pressure curve, and one of the controls for the nozzle switching is pressure, so perhaps it applies when the user is using a mouse rather than a pressure-sensitive stylus.

correct. The Affinity Help explains it like this: 

• Nozzle-specific controller (Pressure, Velocity, Rotation, etc.)—For multi-nozzle brushes, pick a controller from the pop-up menu and click the adjacent Ramp profile icon to select a standard profile from lower thumbnails or create your own using the ramp chart.

My hope was the ".etc" part meant that somehow for the cyclic option the controller ramp set how quickly the brush cycles through the nozzles. I guess the only thing that controls that is the size of the nozzle vs. the dimensions of the stroke ... or some such.

Cyclic with 3 nozzles in my case uses the first nozzle about 20 times then the next one for 20 . It would be really nice if it cycled the nozzles in the way one normally understands the word...  a b c a b c    not  aaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbb,......   ?

 

EDIT   actually it does   aaaaaaaaaaaaabbbbbbbbbbbbbbbccccccccccccccbbbbbbbbbbbbaaaaaaaaaaabbbbbbbbbbbbbbb    😮
