I was thinking about purchasing the Arturia product line for my studio, but have decided not to, because of a very disappointing lack of technical support.
I was not able to get the demo version of the the Mg or CS-80V to work with my protools system, and after waiting many weeks for technical support to reply, they replied with "please download the latest upgrade". After I informed them I was still having problems, I got no further reply.
I've read many complaints on this forum, and would advise anyone wishing to purchase this product to think twice. Anyone who is having or has had problems should post a message or email the company to let them know that this is not acceptable.
This is yet another example of a good idea, implemented badly, with lack of testing and support. Obviously an attempt to make maximum profit with minimum expenditure.
