Thanks DonM and ‘Uncle Dave’for the replies. Your explanation U.D. –--“when the arranger is "on" I am using left hand triggers...almost always. I have developed a style of play that usually voices the chords (right hand) so I can pluck out the melody if needed. I arpeggiate a lot, and sort of "strum" the chords on the piano...more like the rhythmic motion that a guitar does”—cleared it up for me. I just assumed the arranger ‘sensing’ would get ‘confused’-if you played other notes with a chord (on the ‘trigger’ side of the keyboard). I’m sure a lot of this ‘stuff’ will come clear to me when I actually get my hands on a keyboard for awhile.
