I must admit, comparing two arrangers on SMF playback when one of them is a Roland is hardly fair..

After all, Roland basically INVENTED the idea of standardized SMF playback, and have never relinquished their lead at this feature. And given that MOST SMF's are actually prepared on a Roland (for the greatest compatibility) and that even Quicktime Player uses a Roland licensed set of sounds for web playback, the deck is stacked against everything else.

I am sure, if you took a Yamaha made SMF, made on an XG standard keyboard, and then put that file in a Yamaha and a Roland, the Yamaha would come out the victor. The quality of playback in unedited form goes to the brand it was MADE on.

You want to turn this around, take a PA800 style, convert and tweak it for G70, and then play the two back to back in a blind test. THEN, which one sounds 'better'?

I wouldn't bet against the Korg, under those set of circumstances...
