With Scalar 2 in Sequoia, clicking the play button t the left just runs quickly through the chord sequence without completely paying each chord Voicing, as in the Online Scaler 2 course. I have to click on each chord individually to hear the whole Voicing for each chord.
FIXED I had the Playback Chord Duration set to 2 beats. Changing it to 4 beats (1 bar) allowed the full payback of each chord before moving on to the next.
