I have noticed..owners of the MicroArranger, that also own Yamaha arrangers (both PSR s910, and Tyros3 and 4...have appreciated the difference between in their words..live sound of Korg , verses the"fake" overall sound of the Yamaha line..

Everyone that offered up their unsolicited opinion , has stated this to me, maybe not all in the exact words I used, but within the same vein..

The Micro gave them the chance to compare in their own homes with their own sound systems...both brands...

Aftermath..I know several folks have sold their Yamaha gear, not to be replaced by the Micro arranger, but they have moved on to Korg full size keyboards...

I am not sure these folks would air out their findings here on SZ.....(Ian -itis is feared ), but privately, they sincerely offer up opinions that are favorably..Korg..
