randomly played notes not visible in ableton midi editor

hello.

i've got a litte problem regarding a midi note randomizer patch integrated in ableton live. i'm not very experienced yet, so i thought to just integrate it into my bell instrument as a max MIDI effect. as the patch starts off with [midiin] i just have to hit any key of my keyboard to make the sparkling bell sound go off. it doesn't register visually in the MIDI editor, though (which actually makes sense because I'm not hitting any keys anymore). could someone explain to me how to make the randomly output notes appear in the editor, please?

it's probably a very simple job but i'm at the end of my rope here and have absolutely no clue where the solution might be waiting for me… any help would be most appreciated.

thanks!
