i just wanted to share my surround decoder patch, it uses the left out channel for mono surround, and the right out channel for the center channel
it sound pretty nice to me, oh and compare the outputs with a headphone for example
several params are adjustable too (for those wanting a patched stereo width control, there's a few of those in the project )

i think i am going to use it in a diy receiver, not fully sure though.
edit 1: [28 june 2016]
changed some stuff:
1 axoloti for a pair of rear surround channels
1 axoloti for a pair of side surround channels
(lastly) 1 axoloti for a center and subwoofer
no modifications on the left/right channels
