Thanks for the replies!

....as Ianmcnll guessed, yes, I am referring to the notes and chord you use when making a custom style.

In the manual they show a page full of various "C' chords. You select the one that closely matches the notes you want to play.

So if I wanted to do a boogie bass line of C,E,G,B-flat I would then use chord C7-13 or maybe C7-7th., or a couple of others.

However I'm not allowed to stray too far from the flock on these. If I put in a scale note that isn't as advertised it comes out "effed'up.

By the above posts I take it that this is no longer an issue on more recent Yammaha boards?

By the way I like the psr8000 from a "sound" point of view. It can still hold it's own with the newer stuff. The piano and elec guitar sounds are a little anaemic...but other than the problem I'm talking about , it's o.k. basically.

At present I'm unable to locate a person in any of the music/equip shops in this area who's technical knowledge of the boards they sell goes any further than " May I help you?" As soon as I mention the words "composer/sequencer", the blood drains out of their face and they flit off to help another person pick out the right color Kazoo.
