XD3 vs X4 ?

XD3 navigation will be the 1st thing you noitce . On the X4 ...all styles are listed .
All sounds are in categorys .
With XD3 you will have to look more into the screen . Access styles/sounds via the function buttons on side of screen .

NAVIGATION different !

XD3/XD9 will allow you to syncipate a arrangement drum track to a midi sequence .

FYI ........my brother + sister arranger friends ! dano
