Mellotronists

Me, I've always found the oscillators on Korg synths weedy in the extreme. 
The worst example of which, was when I went to see Rick Wakeman in concert a 
few years back. He must have had an exclusive contract with Korg at the time, 
as that's all there were on stage. Maybe he had a useless programmer, but the 
"Moog" lines he played had a sound nearer to a Stylophone than a Mini-Moog. 
And as for Tron impersonations,-there were none!
