Recording with midi note D#4 problem

Using midi note D#4 (which can be setup as a conditional trig) to start recording in the flex buffer. works fine, except there is no volume. Unless I trigger the recording manually…anyone has a clue? I am following Max Marco’s video here. https://www.youtube.com/watch?v=7d3VqUvpg-I&list=PLjeHgrm_ZHd7hbewzSuVlOY7TEkenXgzm&index=5&t=84s
