Not enough complaints, Diki...the drums seem to be just fine for the vast majority...they are part of Yamaha's characteristic polished sound....they aren't going to sound like your G70's drums...they aren't meant to.

Only some of the "pros" seem complain...and they aren't who Yamaha is interested in...Yamaha has a "pro" division for those people...Motif etc.

Yamaha arrangers are considered home product...you know that, buddy...some people are just enterprising enough to use them to make money.
