Good sounding drum sample libraries are two a penny; I have more high quality drum samples than I know what to do with. What matters more is articulation, the ability to adjust the sound in response to the way it is being played. This is particularly challenging for this product as there's no tactile interface, so you've got to infer a lot from positional variation, player velocity, and note speed. I'm not seeing that with their software, which seems only to offer velocity threshold and curve as modulations to volume.
