Hi there,
the MiniFreak V has (different than other Arturia virtual instruments) a bug when launched for the first time within Ableton Live (both 11 and 12)

This is not too big of a problem for me, because closing and opening the window again solves the problem (until the next start of Ableton.

So Arturia might want to look into it.
