I have been using the same mapping for a few years and the other day it suddenly started getting really wonky. I have multiple effect setups on my S2 in “midi-mode” that changed and I have no idea how to get it back to what it was.
I had a buildup effect that grouped peak filter, reverb and iceverb. It now replaced one with a turntable effect and I have no Idea how to get it back.
Also I had a delay freeze setup that changed itself to the gater effect.
As far as your suggestion goes I have done that multiple times as well as removing and re-downloading the .TSI file itself. Everything works as it should but the effects that were originally assigned have switched to other effects.
