thats definitely a good point there Bill about Korg coming from the Synth background.

In terms of tweaking abilities and editing functions, yamaha seems to have less than the korg obviously but i believe the on board a sound quality is better in the sense that the sounds sound more realistic.

also, anyone who really is a serious music producer wouldn't just buy a keyboard hoping it can do all. They would have a good PC/Mac program such as Cubase / Cakewalk / Fruity pro and use a keyboard to go with. most occasions the keyboard is quite basic...

There are always going to be people who pick out things/features that keyboard A doesn't have over keyboard B, who are generally people who have very little knowledge of real music production what so ever.

Generally for people who like to get on there and have a quick bash and get a good realistic sound, any of the high end synths are more than good enough... they each just have different ways or methods of getting there.

cheers,
