I just started to look at this thread.
Correct me if I am wrong but I think when Spalding was talking about creativity he was talking about creative as in how you use an instrument not necessarily creative musically.


The creativeness that was being referred to in the example was that he took a workstation and used it as an arranger.
The fact that persons are say that could easily be done on an arranger only proves the point.

The reverse would be true. I am sure there is someone who could take their G70 and compose a song the same way they would do it on a Motif.

Yes what was being done in the example could be done easier on an arranger rather than a workstation. But it took a creative mind to use a workstation like that.
