Hi @Roskobiwan
Welcome to the forum
You can add or delete notes in a chord on the CHORD page (see Introduction to the CHORD page so it is easy to turn extended chords into triads. This will enable you to select which two or three notes you want for your pad line.
There are a couple of ways to transpose chords, and hence performances within Scaler in either Section A
or on the EDIT page (see Transposing Patterns (aka Changing Key)
Hope this helps
