+Samplebrain (made in 2015) chops samples up into a 'brain' of
+interconnected small sections called blocks which are connected into a
+network by similarity. It processes a target sample, chopping it up
+into blocks in the same way, and tries to match each block with one in
+it's brain to play in realtime.
 
 This allows you to interpret a sound with a different one. Over time
 developing it, we gradually added more and more tweakable parameters
