These demos are completely pointless to me. Sure the Ketron does have a more distinct sound in terms of clarity with the drums but you could get very very close with the other boards depending how you EQ'd the tracks and addedsd/removed effects...

Also - as we all know - with each of these boards you can change the drum kits around AND select different snare samples from the pool of snares that are available amongst other drumkits on board... And guess what - the Roland would do this the easiest and quickest using the make up tools. But none of these demos go into any feature detail... its just a like for like comparison of the same song being played. you could probably do this with 20 other keyboards and they would all sound as similar.

Switching around and re racking those heavy keyboards every time would be a nightmare...
