It has worked for years, since Traktor 2, so my questions are:
1) Is there any way to get to it work?
2) Is there any hope that whatever broke it between 3.5.3 and 3.6.1 will be remedied in a later update?
The mapping is based on Tekken’s Kontrol F1 Ultimate Mapping v3.4, where I changed a bunch of the FX paramaters and moved things around to suit my workflow. People are reporting that the same things that broke in my mapping broke in the original with Traktor 3.6.1, so it's not just me.
What broke are the pad FX that you push once to activate and again to turn off (using Modifiers to determine the state of what is active). In Tekken's mapping these are Echo Freeze 1 and Delay T3, but I have three other effects mapped using the same Modifier set and they are all affected. Basically, you should only need to push the pad once to have it set the FX and the starting paramters and make it active at the same time, but now you have to push the pad twice or the FX does not activate. This makes it useless because the whole point of a pad effect is for it to activate immediately.
I've downgraded to 3.5.3 for now and it's working again. There is no way I will be upgrading until I find a way to resolve this.
