When I try to delete MM V2 with opened editor from a FLStudio project I get Access violation error, crash and finaly Bluescreen. When the editor is closed everything works fine.
Meanwhile I testet Mg Modular on another PC in FLStudio 6.0.8 and after removing this plugin I cannot load any other VSTi "for an unknown reason". I reinstalled FLS, worked once and then the same problem appeared. This plugin works perfectly in Chainer installed on both PC, editor opened or not. Support @ImageLine told me to contact Arturia for this problem.
So, does Arturia have a good support, or not? You can try to contact frederic@flstudio.com
