[PD-dev] help with some new multichannel tools

[Alexandre Torres Porres]

ok, I was able to compile a version that does not blow pd up

obviously I have no idea of what I am doing and I did some things based on
warnings I was getting, but then, I do copy the input first and then
reorder the channels but I do get the exact same result as before, so it
was all for nothing.

here's my new attempt, hopefully not too far from getting things right

cheers
