As far as I can see from this forum there are a number of users both on windows and MacOs who are experiencing various degrees of failure with the standalone MMV.
I notified support about this issue some time ago, with no help. I am using MMV on OSX and it fails to initialise the digi001 HW. I have loads of products from other manufacturers (NI for one) which work fine on my system.
Given that I am apparently not alone in this poor experience maybe Arturia need to be a little more proactive about this.
Any comments/help gratefully received.
