Hi RR.. welcome aboard!
A couple of thoughts.
1) midi has nothing to do with the sound. Not a cause for concern.
2) The 'recommended' EQ if flat. Good sounds/samples really don't need change, except to make up for deficiencies in other equipment.
3) IMHO, Kustom never built good sounding stuff. The fact that you sound better through a Crate just exemplifies this. About the best you could do is A)-Upgrade the Kustom's speakers or get a better system, or B)-Add something like a 31 band graphic EQ between the keyboard and the PA. That'll give you a better chance at modifying the tone into something acceptable. They're pretty cheap, so you might try that first. It won't cure mudiness. That's the Kustom's problem.
Good luck, Paul
