Not everyone can afford an arranger, and a workstation, VST's, synths, clones etc.

I believe Spalding's point is that you can achieve remarkable results within the limitations of your budget and your gear.

If all you have is an arranger that performs multiple duties, such as "live" play, recording and composition, the instrument has a lot of capabilities and power that the average (or even above average) person/player rarely explores.

Someone with Rudess' imagination, creativity and skill, could wring a lot of music out of a G-70, Tyros etc...far more than any of the posters here on SZ, in my opinion.
