Hello,
I believe I found a bug with the objects [cartopol~] and [poltocar~]. Basically, if I would connect both outlets of [cartopol~] to the inlets of [poltocar~], I would expect to receive the same values as I would input. The problem is that the output of the second outlet of [poltocar~] is multiplied by -1! I tested this with both Pd 0.46.5 and pd-extended 0.43.4 (and this bug isn't present in Pd-l2Ork).
Here is an image of the problem: http://s1.postimg.org/bs79w4d5b/Screenshot_from_2015_10_16_22_50_23.png
Is this a known bug?
Cheers, Gilberto
