@LouHela , it sounds like you want to recall the chords from the patterns interactively. Have you tried out this feature?
Basically each pattern can be bound to one of the keys starting at C1 on your keyboard. The keys from C2 on recall the actual chords in the pattern’s progression.
And if you don’t like the default key range for the binding, you can customize this in the settings menu (click on cogwheel in upper right corner of Scaler’s main screen to get to that menu).
