It sounds cool, but I'm still waiting for JHS to come up with something original.

I was just commenting with brejna today, sounds a bit artificial to me, there's something...not quite right with the sound, it has a knee in the wave that doesn't appeal to me. It could have more mass to the sound I guess, sounds a bit thin to me to be honest. Still, the tap tempo is a very cool idea of course. I would probably never use it, but it's cool.
