It appears to me that for the home player, Yamaha has been the traditional winner because of the full sounding styles. If your looking to record your own songs...the drums in the Yamaha (up until Genos and maybe PSR-SX900) lacked punch and definition to sound good enough for recording. I know Gary and others have put countless hours into editing and improving Yammie drums, but to me...they are not strong enough.

I love the ability to just grab a knob on the sd40 and adjust volume quickly. The sd90 has taken that capability to another level. So from an old studio guy...knobs and faders are awesome. I’m to lazy to dig into sub-menus to adjust levels and eq. To me...the more individual control of each instrument the better. That way...you can make styles much more customizable. We’ll have wait and see if the new sx900 offers easier control of this.
