So I've just noticed something very peculiar with my traktor Pro 4 as well as my traktor 3.11.1. When I have ramp delay selected as the effect in FX Unit 1 and then I change from single to group FX, traktor consistently crashes. It does not do this with any of the other effects, only with the ramp delay, and only on effects Unit 1. Is anyone able to please test this on their TP4 or TP3.11.1 and let me know if you are experiencing the same crashes?
