Diki,

"....Your style choices just went exponential, as you get a huge variety of possibilities rather than relying on one arranger for the entire arrangement...."

You are hitting the nail right on the head here. EXPONENTIAL being the key word. Although variety is the spice of life I tend to think that our choices have become too large to comprehend. I mean take me. I do know my way about with my Korg PA the way you do with the G70 but even then perhaps we have only explored what.....70% of its potential. Of course I could have mixed the Roland module with the Yamaha midi wise but due to several reasons one of them concerning my health, I thought I would not bother but rather concentrate on the music.
I even did a houseparty performance a few weeks ago, my first in well over ten years ( go figure !!) and only used my semi acoustic guitar and a number of backing tapes, some of which I had even concocted myself over a number of years. Good fun and I did not even miss my keys ! But like Joe here my main effort would be to re-arrange popclassics and make them sound different with the means at my disposal.
And as to you Donny, forget about it mate, unless of course you are blowing the dollarbills my way ( :)). Seriously though I have never even contemplated going down that avenue.
I guess in retrospect I should have spent the money that I did spend on the BK7m on a used G70 (...which I might still do in time...). If you consider all the styles available that do use the Dynamic Arranger ( take the lot made by Mart Weeho for starters) it is outrageous for Roland to have dropped this feature.
Which brings me to Joe's last comments and song. Thanks by the way for the compliments paid Joe. I take it this is the Motif we are listening to ? As to writing your own stuff, full marks here, I never got beyond some juvenile love stuff , I guess that is why I turned to re-arranging covers. The piano is very good, the sax later on in the song is outstanding. I see what you mean cause this definitely calls for a lady-singer to be sung. The basic accompaniment is very lucid be it a bit too repetitive in my ears, I guess also due to the length of it.But I assume it does take a gargantuan amount of work to get this done on a NON arranger keyboard ?

regards,
John

P.S. Diki, have you ever heard or experienced the Roland SRX-11 piano soundcard ?
