Here's a video of a drumming game I'm developing in my spare time that some of you might be interested in.

I think the (realtime) transcription feature is something that would be cool in Hydrogen. I might release the code for this at some point (but not just yet).

Yeah, instead you only need to lug around 10 cameras :)

That will all change in the next version though.

Stay tuned!

oohhh, crazy. thats amazing!!!

i am wondering about latency and time resolution. for example with 25 frames per second, you have 50ms between each input event. so there must work some very interesting interpolation algorithm (look ahead). to trigger a note on right position. how did you do solve this?

Thanks!

The version of the system shown in the video uses cameras that update at 120Hz (8ms between events). The high update rate is the key to making it feel good and is the reason attempts at making similar systems with the Wiimote or Kinect have failed. That said, my new approach uses inexpensive commodity hardware and works just as well but I don't want to give details about how it's done until I finish it.
