Here is a video of me improvising with just a snare (and some bits) and my Party Van software.

DESCRIPTION AND OVERVIEW
The Party Van is a live sampling and performance instrument built using Max/MSP. It was programmed around the Monome 64 and Arc 2 controllers but includes mapping for an iPad running TouchOSC (custom layout included) as well as the Keith McMillen Softstep foot controller. Additionally, the patch has MIDI learn functionality built in, so every parameter can be mapped to any MIDI controller.
