what's wrong with "set array size"?

[r.erorr]

what I'm trying to do is "get all index[s] > 0" and create new array out of those values. I'm bit confused with result cause set array size somehow doesn't work. In this example set array size is 4 and output is 3, but also other variations happen. Do you know what's wrong here? why output of new size is 3 instead of 4?

ok, solved the problem with "extract sub array" instead of "set array size" and two "wait 1 block" modules.

With this patch I can draw list of different values, set or delete array elements dynamically. For example it is possible to randomize specific samples only: 1,3,8,15 or 13,14,16,2,4,6,9 or whatever . . . That is draw the list for random
