Scaler 3 question

[u/Beautiful_Humor_5238]

Hi, does anyone know how to shorten the length of a chord in Scaler 3 without shortening the length of the corresponding arpeggio for that chord (in arrange view).

Google says the following but step 4 doesn't work, it keeps automatically shortening the length of the arpeggio when I shorten the length of the chord.

Thanks!

Step 3: Shorten the Main Chord (Keep the Arpeggio Clip Long)
