Of which, Yamaha has no shortage. Listen to their demos of their electronic drum line, or some of the kits from the MotifXF and you'll see that Yamaha ARE capable of making punchy, dynamic kits. Yamaha actually make GREAT drums too... so they don't even have to buy or rent a kit to sample!

No... the only reason there aren't great kits in the Yamaha arrangers is Yamaha's refusal to put them there.

Roland don't seem to have a similar problem. They make great (arguably, the most popular) electronic drum kits, approved by drummers everywhere. Multi-velocity drum samples, honed over years to provide a realistic dynamic, sampled with the kind of 'air' around them that drummers expect to hear. Then, they let the arranger division use those samples..!

Yamaha, if they took a leaf out of this book, would never hear a bad word about their arranger kits ever again! They already HAVE the samples. Just not the will to use them.
