The drumbeam is back this year, finished and almost ready to sell.
It’s a bar that can detect where and how hard it is struck, sending USB or regular MIDI. It is made to be played with sticks but is sensitive to light playing. It will detect simultaneous strikes as well. With more than one drumbeam you could create a whole drum kit.
The company that sells it is called AFK Audio.
A little different from a lot of the products shown at SB, but something most here can appreciate.
Best video i found so far is the one phaelam linked, which is from two years ago. More to come for this.
