Hello,

in this patch there are three numerical lists that are merged into a single list, from which are extracted the values in a numeric box, one by one every second.
Everything works fine, except that the extraction of the singles values one by one ​​only works if I go to edit mode and I move slightly the "Three lists merged" list, then the extraction starts correctly. If I reset and merge the lists again, the problem returns.
Why?

list_01.pd

Thanks,

@atux A symbol is not a list. You can use [list] or [list store] instead of [l2s].

symbolnotlist.pd

Also maybe [list-dripslow] can help the extraction.

list_02.pd

Another way is [list store] with counter and [get $1 1(

list_03.pd

Hello

I have analyzed your two patches, disassembling and reassembling them.
The [list store] object is really very useful. Now it's all pretty clear, the advice to send the [print] output of the various steps is essential to understand how this works.
So I rebuilt a new patch with a subpatch inside to create a message where accumulate the extracted values ​​so that the list increases dynamically.

list_04.pd

EDIT:
Here a version of the same patch without [counter] object:
list_04_bis.pd

Thank you,

a.
