Arturia Support confirmed this problem. They were very kind by the way 👍🏻
To my opinion it seems that Arturia treats their synths as individual products. By buying the V-Collection, which has several (semi-)modular synthesizers, I expect it to work like one system, with the possibility to interconnect a Mini to the inputs of the ARP 2600, the ringmodulator of the Modular V to the Buchla etc.
It’s my hope Arturia will give us a “container-VSTi” where we can drop several synths in and use them as one big modular system.
