I imagine the traditional way of playing organ would be in that category as well, Chas...LH chords that support the RH melody, which is why a great many arranger players are former organists.

I have a buddy who plays jazz organ on a CVP-309, and he is pretty awesome...sometimes he uses midi pedals, but generally he can can make it honk with just a good bebop or fast jazz style....pretty hard to distinguish it from a Hammond (he does a great J.Smith impersonation), but it is in the phrasing and dynamics that he manages to pull off such a great performance, and he is not held back by any preconceived limitations of the instrument.

Using custom styles of the performer's own making, also goes a long way to lifting an arranger performance above the standard fare...or using custom voices or layers that one can't get on a piano or traditional(Hammond or clone wheel) to bring a new level to one's presentation of a piece of music.

And of course, there are the chords themselves, and inventive use of them (like using ON BASS, or cool extensions) on an arranger really makes a big difference in the quality of a piece.

There are those who will manage to shine in their respective fields, whether it be arranger playing, jazz/pop organ or just playing LH bass and chords behind a singer or soloist....it all depends on the player and just how far they want to take it.

Long live the the arranger...one of my favorite tools, and a terrific piece of work, considering it's humble origins as an add-on to home organs.
