Hi Notebender
The AWM technology was first introduced by Yamaha around 1985 (Although it has been updated), the Korg is based around the Triton series so probably around 2000.
WARNING: Do not but something just because it is newer; only buy something that suits what you want to do.
Hope this helps
Bill
Yes, thanks for this Bill. The time had expired on editing my last post, but I was going to say something similar.
Often something is technologically better on paper, but the so called improvement may actually be imperceptible.
