Hi, I did the talk on 'A position sensing MIDI percussion interface' at LAC at the weekend. A few people asked me afterwards if they could have more information about it, including construction details, so I'm just posting a link to the page on my website about it: http://highfellow.org/synpad There are links here to an instructables.com article about how to build one, the original youtube demo video, and the latest software release which I used for the talk. Hope people find this useful, andy baxter.
