Um no one is talkinga about music in this case. I am talking about proffessional digital sound, which is now a requirement for some od-ball reason. Arranger workstations are made for live situations, and for song writing ideas. It is not meant to be the easy way out of making music and proffessional arrangements. Anyone who ONLY uses that for their arrangements, will never have that PRO sound you are all striving for. My point was, if you really want that SOUND, your not going to get it from a keyboard alone, actually NEVER. Why do pre-amps, g4's, Sound cards, etc, exist then? I will never believe that one single arranger keyboard will ever take the place of all that.
As far as making music, you are right, you can make great music with a single workstation, but it will always miss something. Live is a different story. I am still amazed what the PA80 does for a live situation. You'll never ever believe that I am playing ALL of that music live with all of my own programmed rhythms.

So again, I'm talking sound, not music,

Thanks
