Hi Ken, Great to hear from you, I think we contacted previously through this forum. I’m 79, so in your age bracket, thank you Graham, I do at times try the extra note in the right hand , from the notes in the chords. Graham, I see your point and thanks for your info re the occasional note dropping and lack of polyphony. I notice this only on Block Harmony, using the Organ Flutes . Using (4 way harmony close ), gives a full sounding chord, without this problem, when using Block harmony. What I would like to know, in the Harmony section, options list the variations, with a small configuration of the notes near the top of screen, and there appears little or no difference between some. For example, 4 way close 4, has same configuration as 4way close 3, and same as 4way close 2. Lead at top, harmonies under in same order. I notice neither manual or reference book goes into more detail on these. Great talking with you, and would like any more info on these settings. I love the 809, and use it as a Genos, my cat would not be kind to a Genos, so 809 it is, with its LID. Ray.
