[Solved] Help: check notes with follow the player position in Patt. Ed

A similar question/idea? → https://forum.renoise.com/t/help-return-a-function-when-a-note-play-in-pattern-editor/47135

Thanks :D! Yes, but this does not help.Long ago I raised something similar, but the conclusion seemed to indicate that it could not be done. However discussing in other forums later with topics related to creating a pianoroll tool,Joule corrected me stating that it is possible to do so. Here I do not want to build a pianoroll tool, but another small thing to identify notes already written in a GUI.

I suppose it is necessary to do something with notifiers, to reactivate on each line or something like that.At the moment, I did not know I could read the notes already writteneven.I am aware that it can influence performance.But there must be some way, and in theory it should be very simple.

The previous function “check note” notify only once, when loading the tool the first time.I suppose I would need to reactivate the notifier when the cursor changes of line in real time (following playback or changing manually the line on each track with the keyboard or mouse), but I do not really know how to do it.
