Hi,
At times, I will find a chord progression that I like from the suggested chords in Section B and use such chords in a song (keeping Scaler locked to Section B). When closing and then re-opening a project, the chords triggered by single MIDI notes do not play unless I re-open Scaler in the re-opened project. I think that once a project is re-opened with Scaler, Scaler should already be active once the play button is pressed.
