Ah interesting, when i use a midi controller knob slowly, it works fine.
If i slam the knob one way, the track control gets stuck somewhere in the middle.
On the gif above, I'm using a footcontroller that goes from 0 to 100 instantly.
So you are probably correct Justin. Thanks for taking the time to look into it.
I guess maybe it can be solved by enlarging the timeframe in wich the parameter can update itslef to account for the lag.
I finally understand why no one was confirming the problem...
