The problem is not the current state, but its herritage..

If Korg would add something akin to Ketrons launchpad feature to their next Kronos.
It would sell like hot cakes with molten chocolate lava inside.

I think its the simplicity of having preplayed intro's and endings, that turns many pro musicians away.
Not the way how the actual chord follwing works, as many are trying to copy exactly this behaviour with their arps or Karma.

The launchpads should work for these critical aclaimed pro's as a fresh start of an entirely new thing, while us arranger players know better.
