Hi, I've raised this with Arturia support - surprised it hasn't been fixed already!
Initially they tried to blame my unit and said i should return it, but after i got a friend to confirm the exact same issue on his unit they have agreed to escalate it to their level 2 support. Fingers crossed it will get fixed as the implementation is really broken at the moment - the e.g. pitch-bend data is screwy on both the sequence channel and the kbd play channel, so it's not even behaving consistently.
I wonder if this issue exists with the new keystep.
