Yes i can confirm this.
I have allready reported this in other threads. It's not only CS80 that's suffer from this. Also other applications has the same fault. It's a very serious fault.
When you play legato style this issue appears. Or when playing multiple notes, then only one note react on aftertouch.
I have understood that Arturia examine this and report back. But they have not yet reported back, so don't know how status is.
