Reply to Good APC20 effects mapping, midifighter style?

I am going to start a new mapping if a glorified APC20 effect mapping has not been made yet. If someone has a similar mapping or knows of one please let me know so then I can build off of it, anyways the title kind of states it.

Also I'm going to be using this with the s4 and I've looked at the sample mapping thats pretty good but are there any other good mappings that I should check out?

It looks like the apc40 gets alot more love than the apc20 when it comes to traktor mappings
