The True Beer and Skittles of Artsy Fartsy Live 8-Bit Sampler Kits.

This unit gives you two independently controllable sample banks, MIDI and CV controls for them, weird bitwise effects, fully open source code, an audio bootloader, free firmware updates, and tons of other stuff you won't find in any other sampler in the world.  Everything else WTPA2-related expands the basic capabilities of this unit.
