It occurs to me, the real reason to change from one keyboard to another is for the benefit of the performer.

I doubt audiences can tell the subtle differences?

It seems audiences that I play for can tell the difference between PA systems though...sometimes.

Audiences, for me anyway, seem to react more to how I entertain...or volume etc.

I really don't think the audiences I play for...age 40's on up....would know whether I was playing a Yamaha, Korg, Ketron, Casio or whatever.

But I would know the difference....guess that's what counts.
