Heather Corcoran and I have pretty much finished work on the Puredance project. The only copy I am maintaining is the MacOSX version which you can find here:

Puredance is a Pd "application" to allow Dance DJs to trigger samples live to a backing track using a dancemat input device connected by USB through the HID object.
It's basically an 8 part polyphonic sampler and file player run by using your feet.
Tomorrow on 29th June at Jongleurs, Bow Wharf, London E3 @ 6pm the system will be tested out in a live performance by a Puredance DJ crew. Ask heather@spacestudios.org.uk if you are interested to see this, there may still be tickets.
Cheers, Andy
